Hi,

I have a 12" Delta disc sander with a 1/2 HP motor. Most every time I
use it , it burns the wood.

Anybody know why?

Yes. The wood is getting hot. It is getting hot because of friction.
The friction is caused by you pushing too hard against a disc that is
(probably) spinning too fast. (I say "probably" because many disc
sanders spin at around 3500 rpm; ones that spin at half that do better.)

The cure is to use a much lighter touch.
