I've installed alot of compasses, coins, inserts, and so on in my bow risers. Always use forstner bits, always drill a test hole in a block of scrap wood to test fit, seal the inside of the hole with a couple coats of clear poly and I never use glue to secure the inserted item (tention fit is enough for me and nothing has ever failed or dropped out).
I get my compasses from 3Rivers. They purchase compasses from the same place that Bear always has, but they get the top grade compass were Bear purchased the lower grade ones for their bows and resale. Had a lot of failures with the low grade ones. I am sure they might be some other manufactures out there but I've never used them. dino
