The sparks flying from the armature and brushes melted the brush holders, broke one brush and melted part of the plastic motor housing. Never seen anything like this. Do you know the max resistance allowed for the armature?

Cool thanks for the info. I noticed also its cutting at an angle away from the saw. Could be the bearings are worn out.

I replaced the brushes for a second time because they start smoking and saw stops. Barely any pressure cutting 1 piece of 4" square tube. I guess I'm going to have to take the whole saw apart to figure out why. It spins smooth and doesn't make any grinding noises, I don't know what is causing...
Does anyone recognize this blast cabinet? Picked it up yesterday. No markings I can find, solid welded aluminum. Looks pretty old.
