As long as I had the lathe torn apart, I added some more screws to hold down the bed ways. I added 8 flat head cap screws in between the existing bed screws. This stiffened up the ways tremendously. When I put a test piece between centers to check for run-out, I put an indicator on the tail stock ram. There was no movement at all when turning. I used to be able to see the tail stock move when turning out-of-round stock. I actually got the best surface finish in steel that I've ever gotten.
The last thing I did was to turn the outside face of the carriage wheel and stamp numbers on it. It is much easier to read now.
