This maybe a silly question, but do the larger 3HP planers not have positive stops on them? My old lunchbox\portable planer had a great positive stop on it. I would just set it at 3/4" and rock and roll until the head bumped up against the stop. On this new Delta 22-790, I have to keep an eye on the progress of each board. With a positive stop all boards were identical thickness, but this having to dial in each board makes them ever so slightly different.....and really annoying.
