Re: Kunz Concave Spokeshave

>Bob,
Because the others have only nice things to say, I guess I'll have to give the other side.
I have the great misfortune to own both a concave and convex Kunz shave. They both reside somewhere, unprotected, around my bench, dissolving into rust--I hope. I don't ever want to see them again.
I fettled, fine-tuned, fiddled, fussed and other things that begin with 'f' (get your mind out of the gutter!) and I never got the &%#$ing things to work worth a tinker's drat. I suppose it's possible to get them to work, but only with a complete overhaul of the sort spelled out in that Fine Woodworking article a while back. I would think leveling the bed and constructing a new cap iron out of 1/4" brass would be the minimum.
On mine, the bed is a long way from being flat. When I tried to flatten it by filing I began to run out of casting long before it got anywhere near flat. Also, filing would open even more a mouth that's already too wide.
The cap iron (hah!) looks like it was stamped, and not like a casting. It has the same trouble as the bed: it's not flat, and it's not beefy enough to stand much file work. And, of course, such a wimpy cap iron in and of itself isn't a good thing.
Because there is no adjustment mechanism, and a single screw holds the iron and cap iron, getting the &%#$ing iron properly extended, AND the cap iron set properly, is a real trial of dexterity, patience and your supply of oaths. I've gotten it close, but never properly adjusted. If you ever do get one right, leave it alone! Don't ever touch it again! Not even to sharpen the iron.
As soon as they came out I bought the three Lee Valley shaves. They are excellent tools and a pleasure to use. A friend has Clifton convex and concave shaves and she finds them to be excellent tools as well. I would say to to steer clear of a Kunz; at best, it will always be a cheap tool.
