I recently bought a Kunz half round spokeshave. I need to hone the blade and I was curious as to what the propper or best bevel angle should be on it. Also any good suggestions for books on sharpening? I tried to search the archives but did not come up with anything anyhelp would be appreciated.
Thanks Charlie

Try 25 degrees. If this folds, then try 30 degrees.

Charlie,
I suspect the biggest difficuty will be getting anything other than the supplied bevel angle onto that curved blade, should you choose to alter it.
The blurb that comes with the curved Veritas spokeshave recommends, for sharpening or even honing, use of a drillpress-mounted drum sander having a diameter a bit less than that of the S/S blade You use microgrit paper (as used in scarey sharp) on the drum and keep the blade tilted so that most of the edge is in contact with the drum.
I'm not sure if this will work to take substantial amounts of metal, as in putting on a new bevel. But you might consider making only a microbevel, if the angle you want is steeper than that of the exiting bevel.......?
Derek will tell me if I'm talking nonsense here. :-)

Addendum: I just found Lee Valleys instructions that go with their spokeshave. They put a 35 degree bevel on it and recommend no regrinding, as it is difficult to keep the sole and blade in registration if you do. Nevertheles there are some useful instructions that may help:

I had a near-death experience honing the blade of my Stanley #55 on a drill press mounted drum sander! Be warned - it is very dangerous!!! The ends of the blade are pointy and, if one of these catches the cloth of the sander, it will be ripped out of your hand and flyyyyyyyyyyyyyyyyyyyyyyyyyyyyy! My wife says that she preferred my having two eyebrows to three (just kidding).
LV also recommend using a round honing rod. You can make these up by either wrapping or glueing sandpaper to a dowel. Preferred method!

Thanks for the info. I used my 1 inch belt sander and got a pretty good edge then I followed it up with a gouge stone and honed the edge. It was probably far from perfect but it cut relatively well. Charlie
