I have an old craftsman radial arm saw that belonged to my father. It has
been sitting for about 8-9 years. I put it back together but the motor
turns very slow without much power. I thing that the brushes need to be
changed as starters. When I looked up on the Sears site for the part number
of the brushes it says the motor is a unit and does not offer parts. Anyone
have any suggestions?

jl, have you checked, maybe the motor is set up to run on 240vac and you
have it plugged into 120vac? I don't know...just an idea...

I don't know how old "old" is, but my early '70s 12" saw could be wired for
either 110v or 220v. You might want to check to make sure the motor wiring
is compatible with the voltage at the wall outlet. I wouldn't rely on the
plug style as a reliable indicator of how the motor is actually wired,
especially on a tool older tool that may have been modified somewhere along
the line.

than universal motors. Perhaps a capacitor has gone bad.

Try turning the saw blade by hand. It should spin freely - if not the
bearing may have partially seized up. This happened to me when I bought my
DW RAS while had been in storage for several years.

I would expect the motor unit to be an induction motor which does not have
brushes.

I can vouch for that! I bought a Delta Unisaw, used from a second hand
shop. I set it up and ripped a 2X4. I was surprised how little power
it had, even if it had the smallest motor, a 1.5 hp. The second thing I
did was check the wiring. It was set up for 220V and had a 120V plug on
the cord. I moved the wiring to 120V as I didn't have a 220 circut on
that wall. It really cuts now! I guess the guy must have tried it,
found the saw had no power, then decided to sell it for $350.00.

John,
I think $350.00 would be very high for a saw with no power. I bought mine (15
year old Craftsman) for $350.00. It works extremely well, lots of power, very
smooth and accurate, and came with lots of goodies.

In article <kecg9.259642$Yd.10...@twister.austin.rr.com>,
j...@hotmail.com says...I' have one and have had the same problem twice over the past 20 years.
I took the motor to a motor shop - repair, rewind, etc. While it doesn't
have brushes, it does have what they called "points" that had to be
cleaned and adjusted - cost about $20 and worked well for a long time.
