Thread: Concave spokeshave

Mate,

I got some flat spokeshaves the other day and I am fresh from looking at them. I do not think that you could grind them to a concave shape without destroying them. The concave spokeshaves http://www.hansbrunnertools.gil.com....ton5500017.jpg

have a curved blade and a curved mouth. If you shaped a flat one you would remove the mouth completely, and 1/2 the cap iron, IMO.
You could use a flat mouth one and create a rounded edge that is made up of small bevels, or maybe get an old wood moulding plane, if the concave ones are too pricey for the job.

Since a spokeshave has such a small/short footprint, it is likely that you can also use a flat version successfully. Both cut a concave shape but the concave ones just cut this tighter.

You're after something along the lines of (c), I suppose?



Yes, you'd have to grind the blade as well as the tool. Grinding a straight spokeshave to concavity sounds like a major bother to me, and I'm not sure it would be possible to preserve the mouth.

Some other options for rounding tools are here:

I've got the "cornering tool set": they work well for straight-grained wood.
