12” x 37” Lathe Tailstock Clamp Improvement

[C-Bag]

Very nice and great info. I've got a similar plate on my 9x20 tail stock and have struggled with it slipping too. It never occurred to me it was the cast iron on cast iron that was part of the problem. I'd gone to a lot of trouble to get rid of the locking bolt and adapting cam lock kit that Little Machine Shop sells for the smaller 7x lathes onto my 9x20. With proper adjustment it works good but I can see now the next step is to get rid of that bottom plate. Pardon the noob question but why do you think the clamping bolt is offset?
