Hello, This is my first post to TB. I never knew it existed until I started researching my latest project, the MIM upgrade. There seems to be a lot of knowledge in the forums here, so I decided to try to get some ideas on how to resolve my problem. Any suggestions would be greatly appreciated. When I removed the original tuning machines from my MIM bass I noticed the bushings had what appeared to be masking tape going all the way around them. I purchased the Schaller replacements, but when I put the new bushings in, they fall right out. I put some masking tape on them and they're still a bit loose. I'm thinking this must be a common problem. What is the best solution? Thanks!
