Hi Mike:

I called Powermatic. They said it was made in 1996. They also are
sending me a correct manual. Mine came with two round rails. The
fence has two locking handles, and was very difficult to move. Not
sure if I will try to make it work or replace it with another fence.
In my case, I already have the VFD, so I'll probably start with that
just to test the motor out. This depends on whether I can find a more
powerful motor cheaply enough. I plan to replace the arbor bearings as
soon as I can get it apart.

Regards,
John.
