    Happy days.
    Just checked the tailstock. It is equal from one end of the lathe to the other.
    So obviously it is the tailstock itself slightly worn not the bed :hug:
    So now if I shim it there should be no variation from one end to the other.

    This was my setup hope I am doing it right?

    Shimming the body up from the base it quite proper. First you should do a suite of checks to see where you're at. A 2-collar test to check how low you are. A sweep along the top of the extended quill to check how much nod down you have. The tailstock ways are least worn up near the chuck so that's where to check it. Put your mag base on the headstock and the DTI on top of the quill then move the tailstock towards the headstock and watch the dial change. Once you have those two figures you can figure out how much shim to use front and rear.

    How much does that height change as you wind the tailstock in and out?

    Haven't checked that yet. Locked the quill in that position so measured the same.
