Anybody using fixturing compound/putty for knife making?

[Drew Riley]

I'm working on some slip joints currently, and having a bit of a time trying to hold the pieces for sanding and such. I got to thinking about some fixturing compound or putty I saw a while back that jewelers and clock makers use. Just curious if anybody had any experience with using it for holding knife parts, blades, etc while hand sanding and such. Is it worth messing with? What's your experience like?

Some of us use double sided tape for temporary holding and for holding small and thin things during sanding.

I've done that as well, or even a dot or two of CA glue, but I was thinking more of after the handles were profiled for instance, where there weren't as many flat spots to stick tape to.

There is a product which we used to hold ceramic substrate to a brass base plate during cutting with a diamond saw. It is a hard hot melt glue which can be disolved with acetone. Th stuff we used was produced by Crystalbond. I believe they make several different versions. http://www.emsdiasum.com/microscopy/products/materials/adhesives.aspx
GRS engraving carries a product called Thermo-Lock, I haven't used it, but if you call them they might send you a sample to try.

u can try bondo mix in a sandwich bag, let it harden around what you want to secure and then break it apart afterwards
