(For context from the original post this is 12" disc, not hand

They run too fast for anything but the lightest of pressure and
briefest
of contact in one place...MUST keep the workpiece moving.

Some woods (cherry perhaps most notoriously) are far more prone to
burning than others, too, of course.

If its an HF type bench sander with a cheap universal brush motor you
might be able to slow it down (with a significant loss in power) with an
external router speed control. If it a single phase AC induction motor.
Nope. Sorry. Light momentary pressure or maybe only sanding
near the
center where the surface speed is less are your only cheap easy answers.


If it's a HF type bench sander I doubt it's still around 13 years
later. ;-)



I have an 8.5x18 HF metal lathe I use in my shop a few days a week every
week that's over 30 years old. I do also have a bigger more powerful
lathe, but that old HF lathe still does its job. It doesn't have a
brush motor though like a lot HF tools. Its got a proper reversible
induction motor. (Their modern mini lathe has a brush motor.)

I bought an old HF wood lathe when I was a teenager. I gave it to a
friend of mine when I was in my 20s. (He did plenty for me.) His
grandson still uses that lathe today. I'm in my 50s.

Now as to my HF belt grinders... (with sanding wheel on the side) The
little 1x30 gets used all the time. In fact I often prefer it to either
of my regular bench grinders depending on the project. It might not
last 13 years, although I think its approaching 10. The 4" belt grinder
with side wheel will probably last 100 years unless I modify it. I
don't use it much. Its so gutless if a fly lands on the belt I have to
take the work piece away or the sudden jolt as it stops when the fly
slams into the table would ruin the work piece.

Anyway, lots of HF tools have lasted more than 13 years. Some under
daily use.
