I’ve had a PM 2014 for about 5 years now. The tail stock has the round clamp plate on the bottom that takes a lot of force to keep the tail stock from moving in use. Saw the Oneway bowl steady hanging on the wall with the rectangular clamp plate. Ordered one from Highland Woodworking. They come threaded for a 1/2-13 bolt so luckily I have a set of 1/2” shank drills up to 1”. Centered it up in the drill press and drilled it out to 3/4”. Works great now. I don’t know if other Powermatic lathes use the round clamp plate but easy enough to change if they do. Those who might not be able to drill one out, can probably find a local shop for a few bucks. You just have to make sure you order the plate for the correct size between the rails.
