In November or December 2008 I bought a used Craftsman Grinder/Sander
model 351.22632 from a local used tool store for $60 or so. *I just got
around to fixing it up.

It is a disk (8" diameter) plus belt (1" wide by 42" long) sander made
of cast iron and steel, with plastic used only for the belt guards, and
it weighs a ton. *The whole thing was made in Taiwan in 1988.

The motor is 1/3 HP, made by Yung Li Hsing Electric Works, looks like a
GE motor, and has a real industrial-motor nameplate. *No "developed HP"
nonsense here.

In the fixup department, all it needed was a new V-belt, and to have
everything properly adjusted and tightened. *Everything was slightly
cockeyed. *

The drive belt it came with appears to have been the original, and had
stretched from the original 38" to 39", and was visibly falling apart. *
Replacing the belt required partial disassembly, which required the
usual set of wrenches, and so probably it never happened. *Many
woodworkers do not have such tools. *(The machine was used mostly for
wood, judging from the sawdust it came with. *There was some metal stuck
in the 8" disk, and there had been a fire in the housing of the 1" belt,
so some metal was ground as well. *Perhaps only once.)

I put a zirconium oxide (purple) belt (made by Sait) in it, and it
really moves metal.

I have not yet found a source for the 8" self-stick zirconium sandpaper
disks. *A prior owner attached some ordinary sandpaper to the disk using
contact cement, so I assume he too was having problems finding the disks.
