ABSTRACT:
An improved planing head for a wood planar is the subject of the present invention. A cylindrical planing head has a plurality of slots which receive the cutting blades and gib means for holding the blades in place during the planing operation. The slots and gibs are designed so that the blade sits on the bottom of the slot and tightening of the gib forces the blade down against the slot bottom. This assures that the blade will always remain in proper alignment. It is preferable to employ jack screws in the bottom of the slot so as to provide means for adjusting the blade height as needed. In either case, the only requirement for realigning a blade when an old blade is taken out and a new blade is put in is to be sure that the bottom of the blade sits on the bottom of the slot where it will be in the exact same position as the previous blade.
