You're probably right. I knew it wasn't the best, just too tempting for the $$$.
Years ago, I used to have a Skil 10" saw. Real POS, almost completely made of plastic, but it had variable speed control built in. I was hoping that the Delta, which is all aluminum & steel, could work with an add-on control. I'm only talking about <1/4" mild steel, brass or aluminum.
Besides giving up the power, would using a VS controller be compatible with it, or could it actually harm the motor?
