Types of Spokeshaves and How to Use Them

Spokeshaves are for cutting and smoothing curves. They give a fine finish which needs no further cleaning up.

Metal spokeshaves are of two patterns: with flat under-surfaces for convex, gentle concave and flat cutting; or with convex surfaces for cutting tight concave curves.

More expensive models have fine blade-adjustment screws at the top of the blade. On less expensive ones you hold the blade in place accurately, then screw the cap iron down tight on it.

Wooden spokeshaves come in patterns for both convex and concave work.

There is a wide variety of spokeshaves for special jobs (including a curved one for bowler hat makers). The most useful of these special-purpose models, as far as the amateur is concerned, is the chamfering spokeshave, with adjustable guides.

 

Points to watch when using spokeshaves: always work with the grain and keep edges square.

Sharpening and adjusting

Metal spokeshave blades are sharpened as plane irons. The blades of wooden spokeshaves need to be honed with a slipstone.

To remove a blade from a wooden spokeshave, tap the points of the tangs with a hammer until the blade slips out — it is only held by friction. Hone the ground edge with the slipstone, then remove the burr from the back with it. Repeat the procedure until all trace of burr disappears. Refit the blade and adjust for depth of cut by tapping the tangs gently with a hammer.

If the tangs will not fit tightly as a result of prolonged use, glue slips of veneer into the tang holes.
