I bought a PC 330 a few years ago. All I have heard on the newsgroup
has been good. I must have gotten the one lemon they produced.

About 6 months ago the clamps that hold the paper developed fatigue
cracks. I got the parts, but it looked like putting them on took a
gorilla with four thumbs. After long discussion with a PC tech, I
got that problem resolved. - It is no easy task to replace them!

Recently, I have noticed that the motor keeps slowing down to about
1/2 speed and then going up to full speed. It only happens when I
place the sander on a piece of wood - no downward pressure applied by
me except to hold it on the wood. I checked the connections and
brushes; they seem to be OK. Anybody had the same experience; what's
the cure?

Thanks,
Len

My old one did this and had the broken springs that I replaced. It was
about 15 years old and I replaced with the same sander. I can only say that
they don't build them like they used to. I was never really impressed with
the newer same model. A couple of years ago I replaced it with a Festool.
