A little update on the hub 'side project'!
Shoes back from the friction application, machined to profile and assembled to the brake plate:
Custom hardware for the rear brake cable machined up ready to have made into a replica cable:
The intake on the CR had a formed/pressed steel 'frame' with a square mesh bonded into it, a super hard shape to form without progressive stamping tooling, as it is curved in two planes and then profiled. The mesh was bonded in with some form of epoxy, and then the whole thing was riveted into the brake plate. A slightly odd arrangement, but it certainly looks very 'works Honda' of the era:
A NOS panel showing the mesh detail:
Machined up press tool:
After much beating/testing the tool was a little battered, but this allowed the thin material to be clamped up whilst it was formed over:
A first off prototype:
A few attempts later, with the closest mesh I could find & some welding wire bonded in to support the bottom edge (like the original):
Brake plate & sprocket vapour blasted up to remove machining marks, and fitted with the mesh guard, riveted into place:
Aside from paint this has finished off the hub project! Time to have some spokes made and rims drilled.
Cheers,
RD17
