I know this has probably already been answered somewhere in this forum but I have no idea where to start looking. I had this same problem about a year ago and ended up having to soak in oil and then scratched up both my Ody and GGTS getting the Ody off with channel locks. Since then I've been very careful to keep the threads lubricated with a little vaseline and haven't had this problem again until today. Ody is bound again and I don't want to scratch it any more. Anybody else have this problem? Any suggestions will be greatly appreciated. And what causes this so I can hopefully avoid it happening again? Thanks!!!
