I spend a lot of time with band instruments. I need to measure the inside
taper of a curved pipe without (BIG WITHOUT) destroying it. Measuring on
the outside and then subtracting wall thickness really doesn't work because
the pipes are drawn and the wall thickness varies.
I was thinking that there should be some plastic like what fishing bait is
made from or the material that is used to make flexible molds that I should
be able to pour in there and then pull out after it gets floppy.
Any ideas what plastics to look at?
Any ideas how to measure the ID of curved tapered pipes?
