As a very amateur wood turner, I find good tools very pricey. Tried making a scraper out of an old file. Came out OK.
Made a paint can forge, using a MAP gas torch. Heated the file till non magnetic, quenched in chainsaw bar oil. [all i had on hand]. Then to the oven for 2 hours at 400. Its sharp, and cuts great, but a metal file scratches the surface, which I believe is a FAIL. Probably wont stay sharp for long. What can I do better to get it hard with basic tools and knowledge?
I also have a piece of M2 precision ground flat bar that I would like to grind into a scraper. Is it possible to "blue" this steel, like cheap carbon steel cutters, or can I just grind away?
