Shop slowed down this afternoon and decided to do some clean up. Well that lasted until I found a scrap piece of 3/8" plate steel. Hum I have a place for you and started cutting out the blade for a spud. It's 8" long overall and 2" wide; the four teeth are 1/2" wide each. I ground and filed the teeth to approx 30°. I then tempered this mild steel by heating the blade until bright red and then dousing it into motor oil, until it cooled to handle. Then I sandblasted it to remove the slag from the oil. Tonight when I get home, I'll heat treat it in the oven; to take away its brittleness. Next will be to weld the 7/8" diameter steel pipe to it, give it a final sharpening and a coat of paint. The question I have, what length should I make the handle/pipe; for ease of use? Also is a tee handle with a tether strap OK? Dan.
