Re: ATM Tool Thickness for Ring Polisher

["Adam Smith" <ajusmith@vaultmaster.com>]

Given the special case of two pieces (ie not three or more) the join is on
the neutral axis and is not under bending stress. I'd glue it, myself, using
Loctite Depend. Warning: the aerosol side if this adhesive is liquid death:
wear a respirator, and good ventilation required.

Epoxy would probably be ok, but I have had better luck with regard to shock
absorption with Depend. I used to glue on knife handle scales with the
stuff, exotic hardwoods to steel, and seldom had a problem.
