    Then one or perhaps two of the tools that I suggested would probably work.

    Yes, I had a bone spur. The shots gave me some relief and, in time, it did go away. But, YMMV.

    Now and for the past several decades I have had back problems. Several doctors have recommended...

    I have built a lot of op amp circuits and this is exactly what I was thinking of. Modern op amps can have a very high input impedance and a very low output one. And to maintain the accuracy, op amp...

    I haven't read the entire thread so this may have been suggested already and I do know it is a PITA to change a 12" chuck, but it sounds to me like you need two chucks, perhaps 12" and a 6" for...

    Mice are easy enough to trap. They love chocolate and peanut butter so use those peanut butter cups for bait. Smooth sided pipe (four inch PVC), standing vertical with a way for them to climb up to...

    Dead sharp tool bit.

    Coolant, preferably an OIL based one.

    Higher cutting speed - within limits.

    Use a leaded alloy.

    I wanted one so I simply made it from a broken, 1/16" bit. It only took minutes.

    OK, if I am reading the question properly, he wants a rougher finish, not a smoother one.

    If it is worth the effort, you could use a boring head in a vertical mill to provide a radius adjustment....

    The motor runs on VFD only: line power is not permitted? How does that work? What's different?

    And referring to rons post #30, just what does "rotor bar design" refer to? I am not a motor guy and...

    I see larger batches as being key to cutting the cycle time per part. I also suggest top/bottom clamping on both one end and part of the center while working on just the free end of the pins. This...

    You seem to be saying opposite things here. In the early paragraphs you talk about a 40 TPI thread, diameter not specified, not being capable of making the adjustments. In addition to the diameter of...

    Yes, they make chucks that you can dial in. The magic is in the back plate, not the chuck itself. They go by names like "True Set" or "Run True".

    First, a serpentine belt is the bees knees on a belted lathe. No more click - click and it runs smooth as glass. In addition to that, I will second the idea of removing the spindle on an older lathe....
