A small belt on my Porter Cable Model 333 Series 2 random orbital sander broke.
The part number is 903373. The typical cost is about $2, but every source I have
checked wants $9 or more for shipping.
Does anyone have a favorite source for parts for Porter Cable tools that has a
more realistic shipping charge? The belt can easily ship in a letter-size
envelope for less than a dollar. There is a local Porter Cable repair facility.
Maybe they have one (which I will check tomorrow.)
As far as I can tell, all the belt does is prevent the pad from going into high
speed when it is not in contact with the sanding surface. It's used to add
friction to the pad's rotation. It doesn't look to me like it will hurt the
sander to operate it without it until I can find a new one.
We're trying to strip the dark, damaged finish off of a 100 year old dining room
table. When the belt broke, we were having marginal results using 80 grit paper.
The wood is hard as a rock. I can't find my belt sander.
