In article , DoN. Nichols says...

But Fitch's experiments in tuning were for the purpose of making
the lathe work *better*. The time it took to spin the spindle up, or to
reverse it was shortened by the tuning -- especially if the lathe was
set to a high gear or belt setting.

Of course this is true, and I suspect that mine would plug reverse
much better if I tuned it properly.

And I do this a fair amount, I've recently been using my
metric transpose gears, so I need to leave the halfnuts
engaged when threading.
