Hi, I recently bought a cheapo $180 belt sander/disk sander combo, and was considering some improvements, one is a new backing for the belt as the current one is just well, the painted frame of the belt sander, and its allready showning signs of wear with just a little sanding.

So, what can one use as a good backing for belt sanders belts?

If you can find it. Ceran the material used in "glass" stove tops. Takes the heat and wear.

A couple of abrasive suppliers also sell a self-adhesive, woven. graphite impregnated fabric expressly for backing the platen. I think Royce Sales is one. They sell at all the wood shows. Duffy

I use a fully hardened piece of A2 steel on my PLATEN. I make them with screw holes in their corners,countersunk on both sides. I can turn them over when one side gets a recess in it.

The cast iron platen on my Wilton square wheel belt grinder doesn't take long to get a hollow spot worn just over the tool rest.

Graphite pads will also get a worn spot.

x2 that graphite platen pads suck.
Cast iron sounds good.
Tool steel sounds like the best.

The graphite fabric pads that most sander manufacturers use is from PEC.

Excellent product.

Beware the cheap knockoffs.
