So, building a copy of a Martin uke which calls for tortoise celluloid binding.
Picked up some Duco from the hardware store only to find (online, before using) that the Duco formula changed, and is not really the recommended method anymore.
More online searching and reading, reading here and elsewhere...other cement recommendations...and make your own cement with Acetone. Or just use Acetone.
Made "mud" with scraps and Acetone. Results=so-so after 24 hours. Binding peeled off fairly easily.
Searching deeper and found a clue (i think) that MEK is needed. Bought MEK and used it straight up (from a syringe) onto a piece of binding and applied to test piece.
After 24 hours, binding was pulled off, but came off in several pieces, and with wood attached. I don't know why Acetone didn't give the same results, as many people seem to swear by it, but MEK seemed to give me a much better result.
I suspect MEK is the ingredient that once was in Duco, but no longer is.
