Lately this has started happening can’t figure it out.
It started when I was sanding some 1/8 veneer I figured it was heat.
But the other day same thing happened with some hard maple boards.

The only thing I’ve changed on the machine is going to hook and loop.
Belts are new.
I’m taking light passes.
Dual drum 80/150 grit.

I keep checking the drums and cleaning them but it doesn’t help.
The way things are now, I can’t use the machine for fear it will ruin the wood.

rwe, I’ve had constant problems with this issue. My drum sander is a Jet. There’s nothing wrong with the sander, but if I don’t have the paper wrapped TIGHTLY around the drum, what happens is that the paper moves enough to overlap itself. The burn occurs where there is overlap.

I hope it’s this easy for you. When it happens, I just unroll the paper and put it back as tightly as I can, being sure to leave about 1/16 of an inch space if that’s possible before running out of drum. The spacing keeps the overlapping at a minimum.

I hope this helps.

“light passes” is a relative term.
I find that even an eighth turn is sometimes too much… especially for maple.
It takes longer to sand (and I use hook and loop too) because of the softer roller with hook and loop.
Also…you probably know this… if there is any overlap of sandpaper during the sanding process, it will show up as burn. Try tightening the hook and loop.

I had a grizzly dual drum sander and it burnt everything. Use only1 drum. Just remover the paper from either drum. I went to a jet single and haven’t burnt anything. Also invest in a rubber block to clean the paper regularly. And lastly just because the paper looks still good it may not be. Good luck and let us know how things work out.

IIRC this started after I installed hook and loop on the first drum.
Now I’m wondering if this is causing the roller to retain heat.
