I was most pleased with the two lines between the man and the horse. I guess it is the shadow of the light, same with the sleigh. What I did is to put a small wheel in the sleigh runners so it would pull along easy. I used a M5 6 speed motor. If we set the motor at a low speed the horse will walk slow; if we change the motor speed to high the horse will run. The horse is a little bigger than the horse Andreas Konkoly built.

Presidential PerusingsPresidential PerusingsPresidential PerusingsPresidential PerusingsPresidential PerusingsMany subscribers to “Canadian MeccaNotes”make full use of a home computer, as is evident bythe fact that well over 80% of them have e-mailaddresses. No doubt the majority, at the veryleast, have explored e-Bay to look at what Meccanois being sold. In addition, many subscribe toSpanner, the Meccanochat line to monitor it.Certainly, I have boughtMeccano on e-Bay(among other things),and both read and occa-sionally contribute toSpanner.

One of the recent topicswith which I was in-volved was somethingthat went under theheading of ‘e-Bayrogues.’ The referencewas to those vendorswho offer something for an inexpensive price, butthen charge an incredible amount for shipping andhandling. Three vendors in particular were men-tioned, but I will refrain from citing the names forlegal reasons. I will, however, describe theexperience I had with one of them.

Up on offer were three 4" Thrust Bearing FlangedDiscs in black - probably repainted - for which thestarting price was £2.70, or around $6.25 Cana-dian. Being the only bidder, I won the lot. Asalways, the stipulation was that the purchasershould pay the shipping and handling costs,something that I was fully prepared to do. Otheritems of a similar nature and weight have beensent to me for £3.50, so this is what I expected topay. Imagine my reaction, therefore, when theinvoice indicated that the postage was £9.99, andthe handling fees were an additional £12.50,bringing the total to £25.68.

It goes without saying that I protested this amount.Before I had time to blink, or so it seemed, thevendor had filed a non-payment dispute with e-Bay. I contacted another C. M. A. M. A. S.member, who recalled that this vendor had beenreported on Spanner before for excessive postageand handling charges. I decided to follow theadvise of another contributor to Spanner - whoresides in Australia - and pay only for the item, andadvised the vendor not to bother to ship the item.By doing this, the contract of sale had been met.There was, of course, no guarantee that thiswould get me off the hook, so to speak.

The strategy worked. The dispute was closed -and, to my great surprise, the feedback from thevendor was the most effusive I have had fromanyone! (I should explain for non-users of e-Baythat, after an e-Bay sale has been concluded, boththe vendor is asked to provide feedback on thepurchaser, and vice versa).

So what happened? In my view, one of threepossible reasons: (a) the vendor is a ‘lurker’ onSpanner, and saw the uncomplimentary com-ments about his shipping and handling charges, or(b) he Googled my name on e-Bay, and saw myinvolvement with C. M. A. M. A. S., or (c) he gotwind of the fact that e-Bay was planning onreviewing all the vendors against whom com-plaints had been registered for charging excessiveprocessing fees. If any other subscriber to “Cana-dian MeccaNotes” has had a similar experience,I would be pleased to hear from them.

Finally, I would like to pay tribute to two individualswho passed away recently, whose names are wellknown in the Meccano world - even if one of themwas not known for his skills in Meccano model-ling.

The first person is Dave Feinstein from SouthAfrica. Dave was the Chairman of theJohannesburg Meccano Hobbyists, and had beenone of the driving forces in keeping Meccano in thepublic eye in his home city. The second is BillThacker, who passed away in December at theage of 91: Bill earned his living as a cartoonist,and, following his retirement, continued to providecartoons for hobby magazines. Bill became amajor contributor to “Constructor Quarterly,” themagazine that Robin Johnson publishes in En-gland. Bill would frequently attend the majorMeccano show in Skegness (SkegEx), and I recallthat I had the pleasure of meeting him there on atleast one occasion. I gather that Bill’s legacy willlive on for a while in “C. Q.” as he gave Robin asignificant collection of unpublished cartoonsshortly before he passed away. Bill came from anearlier era, when his humour was not subjected tothe pressures of political correctness. His witti-cism, however, was never malicious - just goodclean fun.

March Bulk OrderMarch Bulk OrderMarch Bulk OrderMarch Bulk OrderMarch Bulk OrderHello fellow members, the March Bulk Orderhas been processed. Thanks to everyone whoplaced an order. I expect to ship to all clubmembers in April or early May. I have a goodfeeling about 2007, starting with the fact that Iam so pleased that I did not have to increase the

prices and that our sup-pliers are doing an ex-ceptional job. I have hadrequests for custommade parts, such asangle girders, channelgirders, long bolts, su-per short grub screws,and special borediameters for cou-plings. Our sup-pliers are morethan willing to ac-commodate theserequirements. Soif you need some-thing special,

please feel free to contact me to discuss.

I have some “French allen 4mm grubs instock, 5000 in total. One of our members,Doug Armstrong, informed me that thesegrubs hold bosses significantly betterthan the old type, so I decided to bring ina load. The club will selling them for$4.95 for 25, $19.25 for 100, and $96.00for 500.

I have an announcement for a very spe-cial prize draw that will take place at theNovember Show this year. There will be3 prizes drawn the grand one being a“Reproduction Set 9 in red/medium greenwith an Oak Cabinet. Tickets are ob-tained two ways. The first is 1 ticket for$50.00 or 3 for $100.00. The second wayis earned by purchasing ReproductionParts from the club. For every $500.00spent, the member shall receive a ticket.For example if member X spends$1650.00 throughout the year he or shewill earn 3 tickets. The March bulk orderis included, so many of you have ticketsalready. I will keep track of this andinform members of their status. Thetiming of this draw is perfect, just beforeChristmas and will be shipped to thewinner before Santa arrives. What a giftthis would make!

If you wish to purchase tickets, send the moneyto the usual address.

All the best and happy building.

Hot Reversing MillHot Reversing MillHot Reversing MillHot Reversing MillHot Reversing MillBackgroundBackgroundBackgroundBackgroundBackground

The inspiration for this model came from theslabbing mill at Spencer Works, Llanwern, Wales.It was part of my orientation trip around the plantin 1967, prior to spending three years working atthe site.

This type of hot reversingmill takes pre-heated ingots(from the soaking pit) androlls them into slabs, whichthen go to a hot strip mill.Continuous slab casting isnow the preferred method ofmaking slabs.

The basic model was con-structed in 1989, and shownat the British Isles Show inToronto. The model was asuccess in that people of allages seemed to enjoy watch-ing it roll out the Plasticineingot. The roller table driveswere, however, not as effec-tive as I would have liked.The model then went to mybasement for quite sometime, and was rarely dusted

off. When this year’s Hamilton Show came up, Idecided to take it along, and pulled it out of myMeccano ‘junkyard’.

I looked at the engineering and was appalled bysome of it - perhaps I have learned a lot in the pastseventeen years! I started pulling out the rollertables and drives, knowing that I had four weeksto make something better. Several ideas were tried

out - and then panicset in, as my avail-able time was lim-ited. I completed thejob shortly before theshow. While still notentirely happy withthe results, they didoperate reliablythroughout the show.

What follows aresome notes and il-lustrations of the milland its mechanisms,rather than a full de-scription. I don’t seethe mill as a ‘clean’textbook type modelthat others mightwant to build featurefor feature, but someof the ideas might beof interest to otherconstructors.

Mill FoundationMill FoundationMill FoundationMill FoundationMill FoundationThe mill rests on a base defined by 24½” girders.Within this perimeter, the mill stand rests on afoundation of two similar girders, spaced by 5½”girders and a 5½” x 2½” Flat Plate, as shown. Themill stand is constructed of two 7½”” girders oneach side, spaced so as to allow a ½” gap betweenthem, and attached to the foundation by FlangedBrackets (139). At the top, 5½” girders join thestands, braced by 1½” Corner Brackets (133). A5½” x 2½” Flanged Plate is mounted, offset on topof the stand, and is used to mount the nip drivegear.

Mill Roll BearingsMill Roll BearingsMill Roll BearingsMill Roll BearingsMill Roll BearingsBearings for the lower roll are provided by 8-hole1½” Bush Wheels (24), mounted 2½” from thebase of the stands. The upper roller bearings have,of course, to be vertically adjustable to vary the millnip. For each of these, a ½” x ½” Double Bracketis attached to a 6" Screwed Rod (79a) by a nut andcollar (59) through the centre hole (see Fig. 1). TheScrewed Rod does not penetrate the bore of thecollar, allowing the mill roll shaft to rotate freely.A Large Washer (38d) is secured to one side of theDouble Bracket, and a 1½” Perforated Strip to theother, at right angles to the Screwed Rod. Theseact as guides for the upper bearings within the ½”gap between the mill stand girders.

The mill rolls themselves are, on my machine,custom-made from solid brass, drilled to accept astandard Meccano rod, and with slotted ends totake Collars, like the Meccano Wood Roller (106).Even when rolling modelling clay, as opposed tosteel, the rolls and bearings have to withstandconsiderable forces.

Mill Nip DriveMill Nip DriveMill Nip DriveMill Nip DriveMill Nip DriveControl of the mill nip is obtained by using theScrewed Rods, described above, as rams. Eachram is powered via a rotating threaded cuff, madeup of a Socket Coupling (171) with a ThreadedCoupling (63b) secured in the lower socket (aThreaded Boss may be substituted - part 64) anda ½” Pinion (25) secured in the top socket. The cuffis restrained vertically by the Flanged Plate on topof the mill stand and the nip adjustment housing,not described in detail.

Synchronous rotation of the threaded cuffs isachieved by worm drives to the ½” pinions, froma shaft chain driven by a Meccano M5 motor, butany similar arrangement would work. (Wouldn’tit be nice if someone made a small pinion with athreaded, rather than drilled boss - could be usefulfor simulated hydraulic rams!).

Just in time for the show, I was able to devise asimple dial-type nip gauge, one which usesMeccano Cord to reversibly rotate a dial indicatorshaft, depending on the vertical position of theupper roll bearing on one side of the mill.

At the mill ‘pulpit,’ control of the mill nip is providedby a small DP/DT switch. As a future refinement,I might wire this through limit switches on the nip(mañana!).

The rollers on each table usetwo types - one consists of aplastic tube with SmallFlanged Wheels (20b) at eachend, and the others are madeof aluminum tube withwooden plugs. There is noparticular reason, other thanwhat was available and con-venient, and suitable rollscould be made in a variety ofways. The Meccano WoodRoller is unfortunatelygrooved (for use as a reel-upmandrel in a loom), and isnot really suitable.

Each table has ten rolls, theinner five of which can bedriven as needed, via a chaindrive from the lower roll shaftand a clutch. The driven rollsare geared together by a trainof ½” pinions, the intermedi-ate ones being idlers. Theshaft of the middle drive rolleron each side of the mill is extended and mounts thesprocket and clutch. See Fig. 3, below.

The roller drive clutches are actuated by anarrangement of levers and cams, so that whenpressure is exerted on the Socket Coupling to-wards the Pulley with Motor Tyre, the drive fromthe chain is taken up. Levers on the pulpit, eachside of the main reversing lever, control theindividual tables.

Mill DriveMill DriveMill DriveMill DriveMill DriveA Meccano E15R motor is used for the main drive.The drive is taken through a series of reductiongears, with an overall reduction of 196:1, achievedby a 4:1 reduction on the motor frame (26c and27d), followed by a double train of 7:1 (part 25 andClock Kit 4½”, 175 tooth gear wheels). There aretwo output shafts, rotating at the same speed inopposite direction, for the upper and lower rolls,respectively. Universally-jointed drive shafts leadfrom the gearbox to the mill stand. Because of thevertical adjustment of the mill nip, the upper rolldrive undergoes a considerable displacement.This drive is of fixed length, but no plunge couplingwas found necessary, as the small lateral dis-placement of the upper roll shaft accommodatingvariations. The universal couplings used are of theMärklin type, as these have proved to be sturdierand more reliable than the standard Meccanotype.

The mill is activated by moving a lever, providingforward, reverse and neutral. This is linked to thereversing switch on the E15R motor (which,having field coils rather than permanent magnets,is not externally reversible: this motor can also berun on AC, but I opted to use variable DC).

Mill Brake and Safety Shut-Mill Brake and Safety Shut-Mill Brake and Safety Shut-Mill Brake and Safety Shut-Mill Brake and Safety Shut-OffOffOffOffOff

A spoon brake is provided, which acts on a brakedrum comprised of a Boiler End and an 8-holeBush Wheel mounted directly on the rotor shaft ofthe E15R motor. The brake is controlled from apedal at the pulpit, via a rod and lever linkage. Thisdevice is useful in braking the mill when reversing,as the high gearing and momentum of the geartrain makes the mill run on for several secondswhen the motor switch is moved to the neutralposition.

Because the mill has the ability to roll out fingersjust as easily as the ingots, I provided a safetybrake and shut-off mechanism which, when acti-vated, stops the mill dead. Cords run in front ofeach face of the mill nip, just above the maximumthickness of the ingots used. These are tensionedand connect to an arm which keeps a pivotedcurved-shoe external brake off the brake drum, thetop of the arm forming a sear. If the cords aredeflected, the sear is triggered and the brake shoe(which is spring-loaded) clamps onto the drum. At

March 2007March 2007March 2007March 2007March 2007 Canadian MeccaNotes 9Canadian MeccaNotes 9Canadian MeccaNotes 9Canadian MeccaNotes 9Canadian MeccaNotes 9

the opposite side of the brakeshoe pivot is a 1½” Bolt which,as the shoe pivots, strikes anon/off switch. Once stoppedin this way, the mill can onlybe re-activated by resettingthe sear and turning the switchback on.

A further safety feature is apush-button operated piezo-electric buzzer, mounted onthe mill stand, which can beused to warn those whosefingers might be wanderinginto the danger zone.

1915 Waterloo Boy1915 Waterloo Boy1915 Waterloo Boy1915 Waterloo Boy1915 Waterloo BoyTractor Model RTractor Model RTractor Model RTractor Model RTractor Model R

The Waterloo Gasoline Engine Company begantractor production in 1911 with a variety ofmodels. The first version of the Waterloo BoyModel R was introduced in 1914. Twelvedifferent styles were produced all with only asingle forward and reverse gear. The Model Nwas introduced in 1917with a second forward gear.The Deere and Company(John Deere) purchased theWaterloo Gasoline EngineCo. in March 1918 and con-tinued the Model R produc-tion through to 1919.

The Meccano model wasscaled from an ERTL one-sixteenth scale die-castmetal representation (No.559) of the 1915 Model Rtractor. This particularmodel has a front axle piv-oted at the centre and issteered by chain in a fash-ion similar to old tractionengines. It also has theteeth on the outside of thelarge gear rings fixed to therear wheels. These gear

rings determined the scale of the Meccanomodel since two Exacto 150 tooth Circular GearRings (part 145A) were available. The Meccanomodel is approximately 3.3 times the size of theERTL model, or one fifth the size of the proto-type. The model weighs about 30 pounds andis 2.5 feet long measured from the front wheelsto the back of the driver’s seat.

Notes:

1. Double or triple thicknessesof plates or strips were usedfor most bearings.

2. Washers spelt with a capi-tal “W” are standard MeccanoWashers. Thin washers, de-noted by lower case, are brassM4 washers about half thethickness of Meccano Wash-ers. Washers were used un-der most Bolts and Nuts.

3. Numbers in brackets “(1)”refer to specific componentsmarked on the figures.

4. Right is the side when look-ing forward from the back ofthe model (i.e. the side withthe steering wheel and driver’sseat).

FrameFrameFrameFrameFrameThe main frame on each side, extending front toback, consists of channel girders built up frompairs of Angle Girders joined by their roundholes by Flat Girders (Fig. 1). Referring to Fig. 2,starting at the front, 2½” channelgirders (1) on each side are linked attheir back ends to 9½” channel gird-ers (2) by 1½” Strips in the upper andlower elongated holes. The link isstrengthened by an Obtuse AngleBracket placed on the inside of thebend in the upper round holes of the2½” and 9½” channel girders. The2½” channel girders on each sideare linked at the front, top and bot-tom, by 4" Curved Strips Stepped(part 89B).

The 9½” channel girders (2) splayout and are joined to another pair of9½” channel girders (3) (Fig. 3), thelatter being parallel and linked acrossthe back by 9½” Angle Girders (Fig.4). The upper 9½” Angle Girder (4)has elongated holes horizontal andpointing to the rear. The lower 9½”Angle Girder (5) has round holeshorizontal and pointing to the rear,

and is offset by three Wash-ers below the end holes of thechannel girders. The 9½”channel girders (2 and 3) arelinked together by 1½” Stripsbelow, Obtuse Angle Brack-ets on the inside of the joins,and by Fishplates below theupper flange. (A Narrow Fish-plate is used on the left side.)Another 9½” Angle Girder (6)(Fig. 3) links the rear 9½” chan-nel girders (3) by their lowerflange (fourteenth hole fromthe back). The Angle Girder(6) is fixed by its round holeswhich point front. An 8½”Angle Girder (7) (built up from3" and 5½” Angle Girders) isfixed by its elongated holes(pointing to the rear) on thetop fourth hole from the backend of the middle 9½” chan-nel girders (Fig. 5).

An inverted U-girder (8) extends the entire lengthdown the centre of the frame and consists oftwo overlapped 18½” Angle Girders, one withround holes and the other by elongated holes(Figs. 2, 3, 5). Both arms are extended down by12½” and 5½” Flat Girders (round holes down)along the entire length, the front hole of each18½” Angle Girder is clear. 1" Flat Girders

(which can be seen just to theright of the Face Plate in Fig. 2)are fixed by their elongatedhole to the free holes in the18½” Angle Girders on eachside. The 18½” U-girder isextended to the front by 2½”Angle Girders bolted to theround hole of the 1" Flat Gird-ers. The lower sides of theFlat Girders are linked byStrips. By extending the 1"Flat Girders to the front asmuch as the elongated holesallow, the side holes of the2½” U-girder extension willalign with the side holes of the2½” channel girders (1). Simi-larly the side holes at the rearof the U-girder will align withthe side holes of the rear 9½”channel girders. A 2" SlottedStrip is fixed on the inside ofthe U to strengthen the jointbetween the 2½” and 18½” U-girders.

The U-girder is attached as follows:

-by a 3½” Screwed Rod fixed by lock nuts to theupper, 4th from the front, side hole of the 2½”channel girder (1), and similarly to the U-girder;

-by the centre hole of the 8½” Angle Girder (7);

Front AxleFront AxleFront AxleFront AxleFront AxleThe front axle swivel support (Fig. 2)consists of a Face Plate bolted bossup to the underside of 2½” AngleGirders bolted by their round holes tothe lower side holes of the 2½” chan-nel girder (1). The front hole of the 2½”Angle Girder is one hole back from thefront of the 2½” channel girders. TheFace Plate tucks in above the lower 4"Curved Strip Stepped at the front ofthe frame. The Face Plate is sup-ported to the rear by an 1½” Bolt thatpasses down through the top of the U-girder (8), through a 2½” Strip and intothe rear peripheral hole of the FacePlate. The Bolt is fastened by a nut tothe U-girder and by lock nuts to theFace Plate and 2½” Strip. A Washerspaces the Face Plate from the Strip.Before the Face Plate is mounted, theswivel support should be attached.

The support consists of four Ob-tuse Corner Brackets (part 133C)each fixed by the centre hole oftheir long arm by a Fishplate anda Narrow Angle Bracket to theFace Plate. The end holes of theshorter arms of the 133Cs arelinked by Angle Brackets. TheAngle Brackets are spaced bywashers to allow a 4½” Axle topass up the centre into the bossof the Face Plate. The Set Screwof the Face Plate should be to thefront for access from the frontend of the U-girder. After theFace Plate has been mounted tothe frame, the front of the framecan be filled in by three FormedSlotted Strips (215) which havehad their radius modified to matchthat of the 4" Curved StripsStepped.

A ¾” Washer is added to the 4½”Axle below the Obtuse CornerBrackets, then a Narrow LargeAxle Collar (Exacto 254A) (withan Aeroplane Collar inside it) thenanother ¾” Washer. A stack of

¾” Washers could be used if the Large Collar isnot available.

Two 4½” Angle Girders are attachedby their round holes above the 9½” Angle Girderby Fishplates in the outer end holes and by 1"Corner Brackets (part 133A) located in the innerend holes of the 4½” Angle Girders. The innerends of the 4½” Angle Girders are separatedfrom the 9½” Angle Girder by using the endholes of the 1" Corner Brackets (Fig. 1). Thedome-head Bolts through theFishplates have their headson the inside of the axle. Two3½” Angle Girders are fas-tened by their elongated holesto the end elongated holes ofthe 9½” Angle Girder by a 3/8"Bolt that passes through theAngle Girders, then four Wash-ers, and into a threaded boreof a Socket Coupling (part171). One end of the axle canbe seen in Fig. 6. Two more3½” Angle Girders are fixedon the back side of the axle byFishplates in the third holefrom the outside ends of the3½” Angle Girders, and by 1"Flat Girders on the inside endsof the 3½” Angle Girders (Fig.2). Use is made of the elon-gated holes in the 1" Flat Gird-ers to separate the back side

arms of the Angle Girders, (tomatch the separation on the front).The 3½” Angle Girders are boltedby their elongated holes to theend holes of the 4½” Girders. Thetop arms of these 3½” Angle Gird-ers are extended towards the cen-tre by 2" Strips which overlap the3½” Angle Girders by two holes.The end holes of the Strips andthe 4½” Angle Girders are linkedby Flat Trunnions by bolts in theelongated side slots. The basesof the Flat Trunnions are boltedtogether leaving the centre holefree for the vertical swiveling 4½”Axle. A built up 12½” Axle, sup-ported in the longitudinal bores ofthe Socket Couplings, carries thefront wheels. The boss of an 1"Bush Wheel (part 518) fits into theSocket Coupling and provides

additional support for the 12½” Axle.

A compound 6½” strip (Fig. 2) consisting ofthree 5½” Strips links the lower end of thevertical 4½” Axle to the centre U-girder bymeans of ½” x 1" Obtuse Angle Brackets (part12D) at each end. (The 12Ds will need to bestraightened slightly.) The lower end of the 4½”Axle passes through the short lug of the 12Dand is held in place by a Collar with Washers forspacing as required. The upper 12D is fixed to

the threaded longitudinal bores of two shortThreaded Bosses (part 64A). The ThreadedBosses are fixed by their transverse threadedbores to the lower 15th and 16th holes(counting from the front) of the centre U-girder. A 2" Slotted Strip (part 55A) fixed byCollars to the 4½” Axle inside the tractor axleprovides auxiliary support. An Obtuse AngleBracket (part 12D) is fixed to the slot in 55Aand is fixed by the short lug to the fifth holeof the compound 6½” Strip.

Front WheelsFront WheelsFront WheelsFront WheelsFront Wheels Pictures of front wheels of Waterloo Boytractors indicate ten spokes. This wasachieved in the model by pairs of 5-holeBush Wheels (Exacto 24D), combined witha rim of Flat Girders totaling 40 holes (12½”and 7½” Flat Girders linked by 3" Flat Gird-ers). Fig. 1 shows the spokes are made upof 2" Axles held by Rod and Strip Connectors(part 212) to the Bush Wheels and by RodSockets (part 179) to the rim. The RodSockets are spaced by Washers from the rimto prevent their threaded portion from pro-truding too far on the outside. The wheelswere assembled on a Geared Roller Bearing(GRB) Plate (replica!) to ensure the rims werecircular and concentric with the Axle. Threadedpins located the rim on the GRB plate.

Rear WheelsRear WheelsRear WheelsRear WheelsRear WheelsFor correct scale, the rearwheels should be about 10¾”in diameter, but the constraintof 16 spokes results in a wheelof 10 3/16" with 64 holes in thecircumference. The rim is builtup from paired 24½” and 7½”Flat Girders joined by 2½” FlatGirders (Figs. 1, 7). The pairsare joined by a number of 1"Narrow Strips.

The weight of the model andthe size of the rear wheelsrequired the use of ExactoLarge Axle (5/16") compo-nents. 4½” Narrow Stripswere used for the spokes ofthe wheel. Starting from theoutside of the wheel, the cen-tre hub (Fig. 7) consists of:

b. Four of the outside spokes are fixed in theslotted holes of the Face Plate but offset backfrom the Face Plate by two Washers. The otherfour outside spokes are extended towards thecentre of the hub by Fishplates fixed by short setscrews. The edges of some of the Fishplatescan be seen in Fig. 8. The inner end of theFishplates are fixed to the inner radial roundholes of the Face Plate (offset by two Washers)by ¾” Bolts. Nuts fix the Fishplates to the FacePlate, then two Washers plus a thin washer areadded.

c. A large axle Square Bearing Plate (Exacto252) (the red edge can be seen in Fig. 8) isslipped over the ¾” Bolts with boss inward.Before tightening the nuts on the ¾” Boltsinsert a large axle Narrow Collar (Exacto 254A)with grub screw between the Face Plate and theSquare Bearing Plate. The Narrow Collar will fixthe wheel on the large axle but also will let thewheel turn freely on the large axle.

d. Not having a large axle Face Plate withoutboss, a large axle 2½”, 95T Toothed Disc(Exacto 251B) was used to secure the remain-ing eight spokes which are fixed to the side ofthe Toothed Disc closest to the tractor. Theseeight spokes are attached to the Toothed Disc

in the same manner as the outside eightspokes. The ends of the outside eight spokesare fixed to the rim by ½” x 1" Narrow AngleBrackets (part 812B) with the short lugpointing out and fastened to the second rowof holes from the outside of the wheel rim.The ends of the inside eight spokes are alsofixed to the rim by Narrow Angle Bracketswith the short lug pointing in towards thetractor to the third row of holes from theoutside of the wheel rim.

e. Each rear wheel is driven by a Large Tooth150T Circular Gear Ring (Exacto 145A). Six3½” Narrow Strips are the spokes linkingthe Circular Gear to the large axle six holeBush Wheel (Exacto 253A). The ends of theNarrow Strips are offset to the outside of theCircular Gear by a plastic Mini Spacer, sothe ends of the Narrow Strips do not foul thedriving pinion. The boss of the Bush Wheelpoints out (away from the tractor) and is freeto turn on the large axle. A large axle NarrowCollar holds the Bush Wheel against theToothed Disc (discussed in “d” above).

f. A large axle Collar is added to space thewheel out from the fender.

The drive from the Circular Gear Ring to the rimof the wheel is by three 4" Screwed Rods (Ashok80E) fixed to the end holes of three of the 3½”

Narrow Strips by Narrow Angle Brackets, and tothe rim by Narrow Obtuse Angle Brackets fixedto the third row of holes from the outside of thewheel rim.

Bolts were placed in all the holes in the secondand third rows in the rim to smooth out thetravel. However there was little traction onsmooth surfaces. Two trailer tire inner tubeswere purchased and cut around the circumfer-ence to provide tires for the rear wheels.

Rear AxleRear AxleRear AxleRear AxleRear AxleA 3½” Large Axle (Exacto256C) was used in the leftwheel and a 9 5/8" length of 5/16" rod was used in the rightwheel. The two axles werejoined by Large Axle Coupling(Exacto 255) which is reallyintended to link a 5/16" axlewith a 3/8" boss. However itworks. 5/16" rod is readilyavailable and a single largeaxle could be cut. Howeveraccessing the Narrow Collar,as described in section ‘c’above, to remove the wheel isnot easy; it is easier to loosenthe Large Axle Coupling.

The large axle is journalled oneach side of the frame inSquare Bearing Plates each ofwhich is fixed in the centre

transverse threaded bore of twoCouplings (Fig. 9). The Couplingsare fixed in the third and sixthholes (counting from the back) by3/8" Bolts inserted down throughthe lower flange of the rear 9½”channel girder. The lower flange isstrengthened by a 2½” Strip andthe Couplings are offset from theflange by Washers. The amount ofoffset required is determined bythe diameter of the Circular Gearand the location of the driving pin-ion. For the gears used in thismodel, the centre to centre sepa-ration for the gears was four inchesand two Washers and the 2½”Strip provided the necessary off-set. A 9½” Screwed Rod (part78C) held by lock nuts in the lowermiddle hole of the Square BearingPlates adds rigidity (the end of the

Screwed Rod can be seen in Fig. 9; and some ofits length in Fig. 3).

The Strips aresupported by 1" x 1" Angle Brackets which arebolted to the rear, upper transverse 9½” AngleGirder (4). The Strips are further supported bya pair of 1" Corner Brackets. The lower end ofthe 8" Axle is fixed to a Univer-sal Coupling, the other end ofwhich is fixed to another 8"Axle (Fig. 3). This Axle isjournalled in a pair of 1" CornerBrackets bolted to the verticalflange of the lower transverse9½” Angle Girder (6). Thefront end of the Axle isjournalled in the lugs of an ½”x 1½” Double Angle Stripwhich is bolted to the elon-gated holes of an 1½” FlatGirder which in turn is boltedto the elongated holes of an1½” Angle Girder. The AngleGirder is fixed to the lowerflange of the middle 9½” chan-nel girder (2) by all of the fol-lowing: -an 1½” Strip in thethird elongated hole (count-ing from the back) of the lowerflange of the channel girder;the other end of the Strip is

bolted to the rear round holeof the 1½” Angle Girder; -an 1"Triangular Plate bolted to thesixth and seventh holes of thelower flange of the channelgirder, and bolted to the frontround hole of the 1½” AngleGirder; -a ½” x ½” AngleBracket bolted by its roundhole to the lower flange of thechannel girder, and to themiddle elongated hole of the1½” Angle Girder. This latterBolt also fixes the end hole ofa Crank (part 62). The Crank isalso bolted to the centre elon-gated hole of the 1½” FlatGirder. The head of this Bolt isbetween the ½” x 1½” DoubleAngle Strip and the 1½” FlatGirder. The 8" Axle supports aWorm Gear between the lugsof the Double Angle Stripwhich meshes with a 25T Pin-

ion fixed on another 8" Axle journalled in theCranks. The mount for the latter 8" Axle on theleft side of the frame is similar except the 1½”Flat Girder is replaced by a Flat Trunnion.

The chain drive for the steering consists of twoSleeve Pieces placed end to end on the Axle andsupported on their outer ends by ¾” FlangedWheels and on the inner ends by Chimney

EngineEngineEngineEngineEngineThe Meccano modelincludes a represen-tation of the twin side-by-side cylinder en-gine in the Model R.The base of the crank-case (can be seen inFigs. 3, 10) consistsof two 1½” x 3" FlatPlates separated by a3" Strip all linked by1½” Strips on their leftand right ends. Thebase is linked to 3"Strips on the front andback of the crankcaseby Angle Brackets.The end holes of ad-ditional 3" Strips (thetop edge of the frontStrip can be seen nearthe bottom of Fig. 10) are linked by four CornerBrackets (part 133A) to the end holes of the firsttwo Strips, with the free hole in the CornerBracket arms pointing to the left and right. Thefree holes are bolted to the lower holes of theflanges of 2½” x 3½” Flanged Plates which arethe left and right sides of the crankcase andform the bearings for the ‘crankshaft’ (i.e. theaxle for the flywheel). A 3½” Strip (the first threeholes can be seen in the lower left of Fig. 10) isfixed horizontally by Angle Brackets along thebase of the right Flanged plate to be used toattach the crankcase to the frame channel girder.

The Flanged Plates are extended upwards bythree 3" Strips on both sides of the crankcase(Fig. 1, upper left of Fig. 4). These are joined atthe back by the elongated holes of an 1½” AngleGirder (Fig. 10, zinc finish) on each side. Thetwo lower Strips are joined and extended to thefront by an 1" Flat Girder (elongated holes down).The front end holes of each of the top Strips arelinked by a built-up Double Angle Strip (1½” and2½” Double Angle Strips) (Fig. 10). The frontend holes of the upper two 3" Strips on each sideare linked by Narrow Fishplates located insidethe lugs of the built up Double Angle Strip. A

Curved Strip Stepped(part 90A) is fixed inthe upper, front mosthole of the 1" FlatGirder by a Bolt and aThreaded Boss. Thecurved front sectionof the crankcase(made up of fourCurved Plates (part200), two FormedSlotted Strips oneach side, two 2"Strips over a 3" Stripacross the top, and a3" Strip across thebottom) is hinged atthe bottom and canbe opened by unfas-tening Bolts in thetransverse threadedbore of the Threaded

Bosses on each side. A second Curved Strip isbolted by one end hole to the lower second fromthe front hole of the Flanged plate on each side.A Semi-Circular Plate is bolted on each side tothe lower, front hole of the 1" Flat Girder on eachside and to the second from the bottom, secondfrom the front hole of the Flanged Plate.

The back of the crankcase is constructed withtwo openings for the engine pistons and con-necting rods; although the pistons have yet tobe realized. There are also openings for thevalve push rods. A third 3" Strip is added abovethe two Strips (previously discussed) at thelower back of the crankcase, and is linked to theflanges of the 2½” x 3½” Flanged Plates by thelong arms of 1" x 1½” Corner Brackets (part133B), short arms pointing up. An 1" TriangularPlate is bolted to the two middle holes of the 3"Strip with free hole up. The Strip and TriangularPlate can be partly seen just above and behindthe cam shaft in Fig. 10. The short arms ofanother pair of 1" x 1½” Corner Brackets arebolted, by their end holes, to the top holes of theflange of the Flanged Plates. 2" Strips extendthe long arm of the Corner Brackets inwards,and are behind (i.e. inside the crankcase) the

Corner Brackets. The corner holes of the CornerBrackets are also bolted to the lower roundholes of the 1½” Angle Girders discussed pre-viously. The inner end holes of the 2" Strips holdan 1" Triangular Plate with free hole pointingdown; and then an 1½” Flat Girder (Fig. 10, topcentre) by its lower two holes. Couplings arebolted by their transverse threaded bores insidethe crankcase to the two centre holes of the 2"Strips. A Bolt passes through the end hole of an1½” Strip, then through the free hole of the 1"Triangular Plate and into the longitudinal bore ofa Threaded Boss. The 1½” Strip rests on thelower 1" Triangular Plate but cannot be bolted toit as the holes are not aligned. Four more 1" x1½” Corner Brackets bolted to the two remain-ing round holes in the 1½” Angle Girders and tothe 1½” Flat Girder form the opening for thevalve push rods (Fig. 11).

Each engine cylinder is represented by an 1½”x 5½” Flexible Plate (Figs. 3, 11, 12) curved intoa ten-hole cylinder. The water jacket is repre-sented by a 2½” wide by 20 hole oblong unitbuilt up from a 2½” x 2½” Flexible Plate on top,a 2½” x 2½” Flexible Plate on each side curvedto an one inch radius, continued by a 2½” x 4½”Flexible Plate across the bottom. The FlexiblePlates are reinforced by 5½” and 4½” Stripsfront and back, curved as well. The cylindersare joined to the water jacket by Bolts passingthrough the front, top holes of the water jacket(the Bolts are separated by three clear holes)and similar placed Bolts underneath the waterjacket. The cylinders and water jacket arespaced by a nut and several washers. Thewater jacket is fixed to the back of the crankcaseby an 1 1/8" Bolt passing through the transversebore of a Short Threaded Coupling (part 64A)which is fixed by its longitudinal threaded boreto the centre front hole of the water jacket. The1 1/8" bolt is screwed to the Threaded Boss on

the back of the crankcase previously discussed.Two Couplings are fixed by their end transversethreaded bores to the upper 3" Strip at the backof the crankcase. A Bolt passes through thebottom, back hole of each cylinder and into thecentre, transverse threaded bore of the cou-plings. An Angle Bracket is fixed in the centrehole on the left side of the water jacket, which

is fixed to an ½” x 1" Angle Bracket (Fig.12, lower left) which in turn is fixed by itsshort lug to the centre U-girder but spacedfrom it by a Collar. Two Short Couplingsare fixed as shown in Fig. 12 to the backcentre holes of the water jacket. An 1½”Narrow Strip is spaced from the top of theShort Couplings by Mini-Spacers (part38B). A 3/8" Bolt protrudes up from thecentre hole of the Narrow Strip which willaccept a Rubber Hose (part 58J). A lengthof heavy gauge copper wire is insertedinto the Rubber Hose to maintain theshape of the water pipe. The Short Cou-plings also support the 3" Strip in whichthe push rods slide. The Short Couplingsneed to be spaced by washers from thetop of the water jacket so thatthe push rods can slide freelyin the Couplings that are heldby Pivot Bolts to the Cou-plings previously fastened tothe inside of the crankcase.The push rods are 5½” Axles.The engine valves are repre-sented by the module shownin Figs. 11 and 13. A 3½” Axleis journalled at each end in 1"Corner Brackets, and in theround hole of a Narrow Fish-plate in the centre and held inplace by Aeroplane Collars.The tappets are representedby double 1½” Narrow Stripsfixed by their centre holes toCollars. These are held inposition on the Axle by wash-ers and two Collars. The Cor-ner Brackets are fixed in twoholes of the flanges of CornerFlanged Plates (part 51D). The51Ds are extended to the front(i.e. into the water jacket) by1½” Strips, the end holes of which have 1½”Double Angle Strips fixed. Note that bolts withas small a head as possible should be used toavoid fouling the valve stems and their springs.The four valve stems are represented by 2½”axles. Springs softer than the Meccano varietywere used as the Meccano springs put too largea load on the motor. Additional 1½” Stripsextend down on either side of the centre arm ofthe module spaced from it by three Washers oneach side. ½” x 1" Angle Brackets are fixed bylong lugs to the outside of the Strips. The shortlugs fasten to back, lower holes of the water

jacket. Two Narrow Reversed Angle Brackets(part 825A) are bolted by their round holes to theupper holes in the Corner Flanged Plates. Theelongated holes of the 825As are sandwichedbetween the 3" Strip and the Short ThreadedCouplings discussed previously. Remember togrease the valve stems before inserting in thewater jacket; otherwise they will squeak andthey are difficult to access once installed.

A Norm Lacroix Canon electric motor was in-stalled inside the crankcase at the base bymeans of an 1½” x 1½” Flanged Plate. Areasonable amount of space is available toaccommodate a variety of electric motors. AnAxle Rod that represents the crankshaft isjournalled in the second hole down from the topand third hole from the front flange of the 2½” x3½” Flanged Plates. This Axle has a pair of 2"Pulleys (Fig. 10), bolted together, and a 14TSprocket Wheel (part 96A) fixed to it. A pair ofDriving Bands connect the 2" Pulleys to minia-ture pulleys on the shaft of the electric motor.Chain connects the 14T Sprocket Wheel to a28T Sprocket Wheel (part 95A) on the cam shaftrepresented by a 3½” Axle which is journalled ateach end in the top holes of 1" Triangular Plates.The base of the Triangular Plates are fixed to thefirst 3" Strip above the 2½” x 3½” FlangedPlates, and in the third and fourth holes of theStrip counting from the back, and offset inwardfrom the Strip by a Nut and a few Washers oneach Bolt.

The cams were cut from dam-aged 1" Pulleys. The rim wasfirst hammered flat, then thepulley was cut with snips tothe shape shown in Fig. 14. Itwas often found that the plateon the side of the pulley awayfrom the boss was loose. Thiswas corrected by inserting aBolt through the threaded boreof the boss, and clampingtightly in a vice an ½” ballbearing against the pummelside of the pulley. The Boltprevents the threaded boresfrom collapsing. The edges ofthe cams, which should befiled smooth and greased,push against the push rods(5½” Axles) inside the crank-case.

The cover on the crankcasecarries the magneto and theoil pump for the engine. These

do not do anything in the model but are includedfor show. The housing on the right of the coverwould hold the driving gear, and consists of twoFormed Slotted Strips curved to a radius of 11/16" and two 2" Strips curved as shown in Figs.1 and 15. The five-hole Bush Wheels areattached by Narrow Angle Brackets to centreholes of the Formed Slotted Strips. The insideBush Wheel is also bolted to the top hole of aSemi-Circular Plate which is fixed by AngleBrackets to a 3" Narrow Strip which in turn isfixed by Fishplates to a 2½” x 2½” Flat Plate anda 2½” Flat Girder. The inner Bush Wheel has a2½” Axle fixed in the boss and the Axle also hastwo ¾ Flanged Wheels and an 1" Bush Wheel atthe opposite end. A 3" Strip is curved over theFlanged Wheels and fixed to an ½” x 1" FlangedPlate (part 51C). The magneto is represented bythe 1" Bush Wheel, two 1½” Strips and an ½” x1" Angle Bracket with an 1½” Flat Girder on theleft side. The cover is held on the crankcase bythe two Threaded Bosses (longitudinal threadedbore vertical) that can be seen in Fig. 10.

The small box structure on the right side of thecrankcase (Fig. 1) is constructed using twoCorner Flanged Plates (part 51D) and two 1" x1½” Corner Brackets (part 133B).

The crankcase is fixed to the right side of theframe by two Threaded Bosses (lower edge ofFig 3) held by their transverse bore in the first

and fifth upper side holes of the back 9½”channel girder of the frame. The crankcase isheld in place by two Bolts through the secondand sixth holes of the 3½” Strip (discussedpreviously) that is held by Angle Brackets to thelower holes in the flanges of the right 2½” x 3½”Flanged Plate. An Angle Bracket (can be seen inFig. 10 on the left side of the crankcase justbelow the nut that holds the built up DoubleAngle Strip) is fixed by its round hole to thelower third hole from the back of the left Flangedplate of the crankcase. The left Flanged platerests on the centre U-girder (see Fig. 4). An 1½“ Bolt passes down through the elongated holeof the Angle Bracket and is fixed in a hole of an1” Flat Girder (Fig. 3) held horizontally by an 1½”Angle Girder bolted to the right flange of thecentre U- girder. The 4½” Strip fixed in the otherhole of the 1" Flat Girder supports an Axle thatrepresents the pipe from the water pump.

GearboxGearboxGearboxGearboxGearboxWith the crankcase in place on the frame, anAxle representing the crankshaft should extendto the left side of the tractor. This will locate theside plates of the gearbox, as the crankshaft hasthree bearings: two in the crankcase, and onein the gearbox (actually two in thegearbox for Option 4, see below).There are three or more optionsfor the gearbox:

1) The crankshaft Axle can con-tinue through the left side of thegearbox to which is attached thepower-take-off pulley. A 14TSprocket on the crankshaft Axle isconnected by chain to an 18TSprocket on a 2" Axle located tothe back. A pinion on the 2" Axlemeshes with a gear wheel on an-other Axle one inch below. Thislatter Axle has a 19T Pinion thatengages the 3½” Gear Wheel ofthe differential. This is the sim-plest configuration and means thepower-take-off pulley turns when-ever the electric motor is running,and forward/back/stop is con-trolled by the electric motor. Thisoption was never actually usedand there is no figure showing the power-take-off pulley on the end of the crankshaft.

2) For several years the model had engage/disengage levers for the power-take-off pulleyand for tractor motion. This allows the power-

take-off pulley to be used while the tractor isstationary. This configuration will be describedas Option 2 below.

3) As in the prototype, the model has one speedforward and one speed back controlled by aselector lever located to the left of the driver’sseat.

4) The prototype has a band clutch in theflywheel. The band is made from a non-Meccanobrass strip and will be briefly described. Thisconstruction is very fiddly. It was necessary totrack down a restored Waterloo Boy tractor tolearn how the mechanism worked.
