Inexpensive jig turns sharpening on its head
This scrapwood jig helps you sharpen plane irons accurately and quickly. To build it, bevel the ends of two scrap boards (one about 3" thick, 4" wide and 8" long, and the other about 3⁄4 ×3×8" as shown) to match the bevel angle of the plane iron. Leave the smaller board about 1⁄8 " forward of the other to create a fence to square the iron against; then glue the two boards together.
Position the plane iron against the fence with the bevel slightly above the top face of the jig, and secure it with a screw and washer. Now, guide your sharpening stones against the top of the jig to sharpen the iron in no time.
