What's the best way to sharpen a scrub plane iron w/ a fair bit of
camber to it? I've seen a picture of some sort of jig that mounted the
iron on a pivot and the arc traveled by the edge of the plane iron
created the camber when using a bench grinder.
So far I've not had a lot of luck doing much w/ the grinder besides
really messing things up, so I have some reservations about the above.
Normally I've been using Scary Sharp for my sharpening so far, w/ decent
results as long as I use a jig. This scrub plane iron doesn't look like
it'd lend itself to a regular jig very well.
How sharp does a scrub plane iron have to be to be effective? I guess
sharper would be better, but w/o a jig, I'm not all that good at
sharpening free hand. I can probably make it sharp enough to be
dangerous, but thats about it. Is the whole deal w/ secondary or
tertiary bevels out the window for this application?
Sorry if some of these questions seem silly, but I figured I was better
off asking than guessing...
I know more than enough *nix to do some very destructive things,
and not nearly enough to do very many useful things.
