paradox1559 Posted September 3, 2016 Share Posted September 3, 2016 Has anyone ever used a steering king pin out of a semi to make a knife/sword? I recently came about one and am curious to see if it makes a decent blade. It would definitely make a big one. Pretty sure it's 4320H try researching in the knife section, you will find that 20 points of carbon will no harden. Link to comment Share on other sites More sharing options...
George Geist Posted September 3, 2016 Share Posted September 3, 2016 Don't know about knives but when Jay Sharp was still alive and making tools he used them a lot to make turning hammers and such. Is great steel for toolmaking. George Link to comment Share on other sites More sharing options...
paradox1559 Posted September 3, 2016 Author Share Posted September 3, 2016 Interesting, I've never used a hammer to make a hammer. Do you know of any pictures of his work? Link to comment Share on other sites More sharing options...
George Geist Posted September 3, 2016 Share Posted September 3, 2016 Well.... Maybe start out here: https://search.yahoo.com/search?p=jay+sharp+tools&ei=UTF-8&fr=chrf-yff17 When I first came around the man was already a legend. His tools were always highly sought after and always brought premium prices. You might find stuff of his on ebay but it will always be expensive especially since he's gone now. I read an article in an old American Farriers Journal back in the early '80s written about him where he said he was making his turning hammers out of Kenworth truck kingpins. The guy was definitely a helluva hand. George Link to comment Share on other sites More sharing options...
paradox1559 Posted September 3, 2016 Author Share Posted September 3, 2016 based on what little I could find, the man was an artist. The world is probably poorer for his loss. Link to comment Share on other sites More sharing options...
SmoothBore Posted September 3, 2016 Share Posted September 3, 2016 About 25 years ago, I replaced the Kingpins in my old Ford Backhoe, and used the old ones to make punches and Hardy tools. They're still going strong ..... I didn't know, ... or care, ... what they were made of, ... and still don't. Link to comment Share on other sites More sharing options...
Deathcat Posted January 11, 2017 Share Posted January 11, 2017 Just wondering if anyone has had any luck with these just got a few as well and wondering if anyone has any experience with them. Also how to heat treat as I've heard they tend to chip bad. Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted January 11, 2017 Share Posted January 11, 2017 If you have a few experiment with one of them. Cut one into identical pieces, and try some different heats and quenching, then compare the results. Try contacting a manufacturer (Kenworth, Peterbilt, Freightliner, aftermarkets) of them, and ask what they use? Many times I have had them contact me back which reduces the guessing.
