natenaaron Posted March 31, 2016 Share Posted March 31, 2016 I have a few milled crank shafts I thought someone was going to buy but their client decided it was too expensive to have someone rebuild a 20 year old outboard motor. So before I scrap them is there something blacksmith wise I can do with the,. I know 4130 is used to make crank shafts but no idea if these were made from that. Definitely some hard steel. While I am on the subject of crank shafts what about cast crank shafts, are they good for something. I have two that are cast but not worth anything, as far as I can tell. The numbers come back to old farm equipment Quote Link to comment Share on other sites More sharing options...
