Hi Fred,

I suggest you get some Cyanoacrylate clue. It come is various viscosities.
The one I like is blue labeled Super Thin with a cure rate of 1-3 sec.

Experiment with this on some test items until you feel comfortable with its
running action.

A companion product is Un -Cure, a debonder.

The glue is space age technology, and will work with anything.

Best Source: Your local hobby shop.

I also have some spare parts that might work though they are Japanese, not
C-P.
