A while back I think there was a post that mentioned use of a belt sander to sand out the corrosion on the back of a chisel blade or plane iron.
Am I remembering correctly? If so, what is the technique and how do you prevent getting the steel too hot? Finally, what grit belts, etc., do you use?
Is belt sanding the corrosion on the back of the chisel or plane iron a bad idea? It takes me a long time by hand.
Is there a better way?
Thanks and regards,
