I am talking about the heavy wheels that TM uses. The foam doesn't stay on the rim very well. They use a low adhesive glue like rubber cement. Jaco has the same problem. That's why I switched 3 years ago to BSR. This problem has nothing to with the arbor or the lathe. I was only using TM as an example because they have goofy wheels that don't fit many arbors but the one that RD Logics made only fit their wheel.
I had a friend fix the nut that presses against the arbor and it all works fine. I was amazed on how little RD Logics knew about "pan cars". They didn't know what I was talking about. They asked what kind of car is a pan car and they finally asked me if it was a 10L, I said yeah about 20 years newer though. ??????
