Dowel Plates

A dowel plate is very handy for accurately sizing dowels from any type of wood you choose. It can also be used to create a tenon on the end of a piece such as a chair spindle.

Short pieces are easier to handle, but any length is fine. When making your own dowel, get as close as you can to the correct size with a plane, spokeshave or drawknife. The blank does not have to be very smooth, though — small facets will disappear quickly. A bit of experimenting will tell you how close to make your blank, depending on the type of wood, length of dowel and how smooth a finish you desire.

Chamfer the leading end of the blank with a knife to make it easy to start the cut. Hammer the blank through the hole. You can also use it to size purchased dowels.

Mount the Dowel Plate with wood screws over a series of relief holes in a bench, or clamp it over a dog hole for temporary use.


The Dowel Plate is 5/16" A2 Tool Steel hardened to Rockwell 60-62, cryogenically treated and double tempered.


If the Dowel Plate ever needs it, hone the top cutting surface with water stones to sharpen. Keep oiled to prevent rusting.
