Convex Sole Block Plane



Convex Sole Block Plane

This small block plane is perfect for all sorts of hollowing jobs like chair seats, moldings and model making. The sole of the plane is 1-1/4" wide x 3-1/2" long. Overall length, including the squirrel-tail handle, is 4-7/8". The sole has a convex radius of 3" in the width and 27" in the length.

Ductile Iron body, Bronze cap.

  • Blade is 7/8" wide, 1/8" thick, A2 steel.
  • Blade is ground to a 7/8" radius and bedded at 20º.
  • Weight 8.8 oz.

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.

Blade Sharpening

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.

Blade Adjustment:

Slightly loosen the pressure of the cap and advance or retract the blade. Tighten the thumbscrew


Fully stress-relieved Ductile Iron body. Manganese Bronze cap. The blade is A-2 Tool Steel hardened to Rockwell 60-62, cryogenically treated and double tempered. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time. After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly. The 1/8" thickness provides solid, chatter-free cutting.


You should oil and wrap your tool after each use. We recommend Camellia or Jojoba Oil - vegetable oil based products. They are non-toxic, odor-free and easy to use. Also, in our shop, we use a fine abrasive handblock to remove any light surface oxide from tool bodies and blades. The oils and the abrasive handblock are available from us.

Materials and workmanship are guaranteed for the life of your tool. Call for repairs or replacement parts. We are available for advice if you ever have a problem using your tool.

Proposition 65 Notice:

Bronze and brass alloys contain lead, a chemical known to the State of California to cause cancer and birth defects, or other reproductive harm. Wash hands after handling.
