I made some upgrades to my Gingery Lathe. First thing I had to change was the tail stock. When I bored it out, I did not get a good bore all the way through the tail stock. This ended up with the tail stock ram being tight in one part and loose in the others. When I would clamp it down with the set screw, the ram would get put out of alignment. I started by purchasing a grinding wheel (on sale at Menards for $25.00) and grinding a new cutting bit. I bored the tail stock until it had a nice consistent bore all the way through. It ended up at .783" diameter. I then made a new ram on the Craftsman lathe. I turned it until it was .001" oversize and sanded with emery cloth until it would slide through with a little bit of force. I then remade the rear cap and tail stock screw. It works real well now. No play anywhere.
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.
