My Powermatic 1200 has a reversing switch. It seems to work very
nicely for me.

That drum switch is NOT a proper "Big Red Panic Button" that you can
mash if things go very wrong, and we both know it. Install one, NOW.
Better yet install two, one high and one low. It doesn't have to be
beautiful, it just has to work.

Do you really want 100 of your best buds all yelling "I Told You
So!!" as you learn to type while short a digit or two for the rest of
your life? Or worse, the whole arm?

Oh, and that drum switch better be connected as a signal-level input
to the VFD, and not be line voltage between the VFD and the motor.
Most VFD's do NOT like it when you open the motor leads under load,
the Magic Smoke tends to escape from the transistors.
