Hello Joe. Your gear train is unique. If I understand your problem correctly, the free floating gear is un-screwing its self when cutting. I can think of a number of different way to stop that from happening. The turning of the gear and friction cause it to un-scew, or screw its tighter when rotating the other direction, If your gear is free floating, do you have it on a bushing or a bearing? If so a little lubricant couldn't hurt to keep it form binding. As someone already suggested Lock-tight, on the screw thread might also help? but I think the screw its self it the problem, how about using a pin or rivet.(or perhaps a clevis bolt could be use or made?) to have the gear ride on, and then add a locking nut, or perhaps a cotter pin, (something that could not un-screw.) A lot of the OLD equipment that I have to work on, has pins, not screw in them to hold things together. perhaps that would be a good idea for you to do as well? If not the easy way to fix your problem could be just spray dyna glide on the gears every job you do on it, If the friction is the problem, lubricant is one way to get the job done. ;-)
I wish you luck. Please let us know how you end up working things out.
