Yeah Crown will profile them. ON3P I think I read have preprofiled side walls.
If you just got a sheet of UHMW and profled it using the same crib or router bridge you do your cores with then you could just cut off strips and use them. Only thing I wonder with that method is how having to apply them to the curve of our side cut after profiling would put the allignment of your core taper/sidewall taper out. If you get what I mean?

He's essentially wondering how the length/thickness changes w/ change in radius.

Profiling a plate of UHMWPE, cut into strips, then applied to a shaped core. I think the difference would be minimal. You could even leave it a mil thicker and take it off in a sanding pass if there is an issue.

yeah that's what I meant Damon. Thanks, much better explanation.
Generally the sidecut is pretty large radius so actually the change in shape from straight is probably not that much you're right, and a bit oversize followed by a sand would be the way to go.

It could be welded (in the materials science sense) together with a solvent.

Application of a slovent at the edges of the pieces will open up the molecular chains of the material. When two pieces are put together the chains entangle and once the solvent has evaporated/boiled off you'd be left with a joint.

Doubt it. Got a readily available solvent for UHMWPE?
