Just thought I’d drop a note to let people know the results of adding “teflon” tape to the weights. This is the white plumber’s tape that people have mentioned. You can buy it at any hardware store cheaply. I figured that I’d try this before I went the epoxy or loctite route. I played with the woods after this and haven’t had the weights loosen up, so I’m happy so far. This is an easy solution if it works. I’ll keep you informed
