So, I've been playing with my DJ20, a 1990 model, and was messing around with some old wood I had laying around. I think this piece may be Doug Fir, but I don't know for certain. In any case, it was bowed up and down the length of the board. I have the cut set at about 1/32", but I don't entirely know how accurate that is. In any case, occasionally, while pushing the board down through the jointer on it's face, the jointer would stall, reset, get up to speed again, and so forth. Am I going too fast? A piece of redwood didn't stall the motor or make it lose speed.
Oh, I don't have my cyclone hooked up, so it's just dumping sawdust to the ground, I don't know if things getting clogged up can cause speed issues either.

Thanks in advance.
