The Chisel Doctor

Accurate, controlled honing for Woodworking chisels and plane blades Good honing guides come in all shapes and sizes - some cheaper and some very expensive with elaborate jigging. This is a new one of moderate cost that works with one our favorite surfaces - alumina zirconia or waterproof silicon carbide PSA-backed (PSA: Pressure Sensitive Adhesive) sandpaper.

This abrasive material used in various grits on a suitable flat surface (glass, marble, laminated plywood etc.) does an absolutely beautiful job preparing a cutting edge. The 3" wide tough nylon rollers provide great stability (this is very important).

With each jig comes a pack of eight pre-cut sheets sized 2-3/4 x 4-1/2" of PSA-backed sandpaper, 100, 150, 220, 320, 400, 600, 1,000 and 1,500 grit. Replacement packs of the 8 assorted grits as originally supplied are available, although you can substitute your own obtained locally from a hardware or auto parts store. If you cannot get PSA papers, use a spray adhesive instead (instructions are provided).

Two rows of guide pins (one of which can be recessed for blades over 1-1/4" wide) are used to reference locate all blades absolutely square to the roller track. The clamp bar can be repositioned in the forward position to securely hold smaller blades, like spokeshave blades.
