I recently noticed that one of my benchplanes has a concave sole. It's not huge but it's noticable when I measure against a straight edge. It's a stanley palne so nothing expensive but i still would like to keep it.

Any remedies are appreciated.

Wind the blade all the way up, so it's not sticking out of the mouth, then sand it flat on a piece of 1/4" glass or a dead flat surface, like a Cast and ground Table saw top. You could also use a belt sander, but don't let it get too hot. Do it until it is dead flat, and square. Check often.

Make it flat. [:Y:]

The best way to do that is with a surface grinder. If you take it to a machine shop, they can grind it flat in just a few minutes.
Another way is to use a flat surface with wet/dry sand paper. A granite block, a cast iron table saw, a glass plate, or a cast and ground aluminum plate should work. Check to make sure it is flat before you start.
Use the sand paper on the flat plate. Start with about 400 grit and water with a little oil or soap as a lubricant. Keep sanding until it is flat. Drop down to 600 and lower grit as desired. It might take you an hour or two. Change sand paper often, after just a few minutes.

Does anybody know the flatness tolerance on float or/vs plate glass?


I can't comment on plate, but the flatness figures for float glass are quoted in units of wavelengths of light per inch - 10 waves/inch for good quality window glass. That's about 5 microns/inch or 0.0002 inches/inch.
