Stave C channel side closeout gluing jig

S YangWP4 monthly meeting at Liverpool University

C channel gluing jig assembly

Some design feature

CF c-channel (same as that used to build the stave) is used as a spacer.

• Face sheet thickness: 0.35mm• Glue layer: 0.1mm• CF C= channel outer dimension: H5.1mm x W4.0mm (refer to Peter’s drawing)

Main frame

C channel tolerance

If C-channel final height is 5.1+0.05, then the glue thickness could be only 0.05mm, so question: should C-channel tolerance be ??

Also if C-channel is on max tolerance, then there will be a gap between clamping piece and C channel inner face; that means there is no positive pressing on the C channel to the face sheet. Therefore, sufficient glue thickness is required to fill in the voids.

Holes for C channel jig

The width of the stave can be adjusted to 110, 115 and 120mm, by moving the top and bottom clamping pieces towards or away from the centre line of the stave .

Holes for stave building tooling

For face sheet alignmentDowel holes for locating the rulers for masking and gluing.
