Hi.
I have an old "Abrasive Machinery Company" model 3B at work. It's big old
monster and does OK, but the X feed is pretty fast and it has a plunger on
the gear box below the manual X feed wheel that is stuck. Can anyone
identify it as a speed selector before i go taking apart a machine that I
cant find parts or a reasonably priced manual for?
