Spokeshave Modification

I bought myself a couple of spokeshaves  from China for very little money. They're not very good quality, but they do work OK with a little bit of fettling. The irons take a decent edge, though how long that edge will last is anyone's guess.

The reason I bought them was because I wanted to see if I could reshape one successfully into a bellied spokeshave for cutting an inside radius, and if it's feasible (and workable) then I'll risk doing it on a better quality tool. The spokeshave on the right has had its leading edge filed down and rounded off for that purpose.

It does work somewhat, but it needs a bit more shaping I think. The front curve needs to be taken right up to the edge of the mouth, and the back edge should be curved away as well, as far as it can be without interfering with the blade adjustment screws. The much reduced sole area in contact with the wood makes the tool a bit more difficult to control, but that's only to be expected.
