When I got my Powermatic 15HH planer last summer I was overjoyed. The Shelix head provided an incredibly nice surface with no tearout whatsoever. However, after planing a few boards I was disappointed that I was getting a little snipe on both ends of the boards. I read through the manual again for any clues and stumbled upon one sentence that referenced a pair of table locking knobs that were on the left side of the planer (as viewed from the infeed table). All the other controls are on the right side.
