I have two of the wooden bodied radi-plane that need sharpening. I'm not
sure how to do this -- I would have to grind a LOT off the flat surface to
get an effective edge, and I don't have a stone with the right radius to
hone the curved edge. Any suggestions are appreciated.
Get a stone with the right radius.
If you don't have one, make a wooden block the right diameter (guess
what, you have just the plane to do it), then wrap silicon carbide
abrasive paper (the black grit) around it. A sawcut down the back
and a popsicle stick as a wedge make it easier to hold.
It happens I just came in from my shop where I sharpened my radi-plane
for the first time. I Scary-Sharpened the blades with 240, 400, 600,
1000, 1500 and 2000 grit silicon wet/dry paper. These are short
blades, a dozen one inch strokes on each grit per side are all you
need. I used the relatively dull blades to round the appropriate curve
on a piece of scrap, and then just held the paper wrapped over the
edge. I polished the flat side on my usual piece of 1/4" glass.
Remember, both surfaces need to be polished for a sharp cutting edge.
In the future, I'll probably sharpen only the curved surface, as
reducing the flat surface may affect the fit of the blade in the body.
