No matter what I did, I couldn’t make the lock hold the ram. So I made a new one. There’s about 1/2” of aluminum at the end of the tailstock, so I drilled and tapped it. A threaded and bent piece of 3/8” rod bears directly on the ram, and doesn’t take a lot of force to hold it. I think if I keep from horsing on it the aluminum threads should hold up. I put a small piece of brass in the threaded hole so the new lock doesn’t gall the ram. I put a bolt in the old lock lever hole, since tightening the new lock would tend to pull that cut apart and loosen the whole thing. It also helped to take up some slight wobble in the ram.

Now I can get to cleaning it up and rebuilding the wobbly stand, and start learning how to turn!
