Ivory Repair

[bevansmw]

I was just curious if anyone had any pointers on repairing some ivory or bone. I'm in the process of restoring a seven day set and I descaled them all and lightly sanded the insides of the scales with some new 220 wet/dry sandpaper following this website as a guide: Society of American Silversmiths - Working With Ivory
Planning on re-sealing the insides when I finish. The one pictured is going to need to be re-sealed entirely.

I'd like to repair a scale that cracked at the hinge pin as one of the scales broke all of the way through at the pin and is in two pieces. I thought to try some two-ton clear weld epoxy and after setting over night that didn't hold extremely well after cleaning it off a bit. I have them cleaned up for a second attempt now and was curious if anyone had some tips, right now I'm thinking maybe the epoxy to hold them a bit and letting it cure again and then some fiberglass backing or maybe just some fiberglass epoxy backing to secure them. Anyone done anything like this before?
