Help!

I have a 20+ year old Craftsman Radial Arm Saw (model 113.199450), on
which the motor just burned out. Sears (noth the website and the phone
help people) says they can no longer get that motor because it's not
made anymore. The motor part # was 63608. Neither can I get parts for
it. At this point, the answer I get from Sears is to just pop on over
to my local Sears store & buy a new saw. However, that's about $600
more than I was hoping to spend.

Are there any other sources in the world for replacement motors? I've
googled the model & part numbers ti no avail. I was hoping someone
here knew of another electric motor source.

I've surfed previous messges in this group, and a recurring theme
mentions a centrifugal switch that's supposed to cut out the starting
circuit. But neither the Sears psrts listing nor the motor itself
reveals anything that looks like a switch. Am I somehow missing it?
