Wow Czechman, (light bulb lights up here)
I was going to get some castle nuts myself and drill a hole in one of the castles for a coter pin so they wouldn't back off, not an easy project I was dreading. The loctite never came to mind. I am glad I read these posting everyonce in a while. Loctite will do just a good a job and be much easier. Plus I think I have some in the bottom drawer of the tool box. Thanks again for the tip!
