I have bought 4 planes in the last month, if spokeshaves count. I am getting very familiar with flattening the backs of plane irons.
Yesterday I put in about two hours on a new Stanley spokeshave iron. I was not too happy about it. I used a DMT extra-coarse stone part of the time, but I eventually put 100 grit paper over the stone and used that. Still pretty slow. I am not really content with the results. I believe there is a small area I should continue to work on.
Is there something faster out there, that either stays flat like a diamond stone or is easily trued up?
