Convex Sole Palm Plane
Our Convex Sole Palm Plane is a miniature workhorse that will do a great job of hollowing chair seats and shaping other concave work. Plane is 4-7/8" long and 1-1/4" wide.
The sole has a radius of 3" from side to side, and 27" from front to back. Blade is 7/8" wide and 1/8" thick. It has a radius of 7/8", and sits in the body at 20°, bevel up. The radius on the mouth is 1-3/16". The smaller blade radius of .900" means that the corners of the blade will not protrude from the mouth when set for a medium or fine shaving.
The blade comes ready to use. Additional honing will improve performance. For honing: One method is to plane a groove in softwood with the blade set for a coarse cut. Charge the resulting groove with honing compound and hone the blade by pulling backwards through the groove. Another method is to shape a groove in a spare or broken waterstone with a 7/8" dowel wrapped with coarse (60-100 grit) sandpaper. Hone the blade by pulling through the groove. For grinding: Re-grind as necessary, following the original bevel angle and radius as closely as possible. Marking the bevel with a felt marker will help you see what you are doing.
Slightly loosen the pressure of the cap and advance or retract the blade. Tighten the thumbscrew
