<p>[QUOTE="Tom Maringer, post: 363471, member: 7033"]Yes, have a pile of 30" long 3/4" W-1 tool steel bars here... probably more than I'll ever use. (I thought it was W-2, but on looking again, it is marked W-1) By "rough finish" I mean they have been sitting around and are rusty... but they WERE finish ground bars once upon a time... so they'll clean up to be very close to 0.750" exactly. I have a chop saw and could knock off a couple 6" or 6 1/2" pieces and turn the ends down square on the lathe. That would give you two ends to work on for each. (If you screwed one up you would have a second chance on the other end). I'd do those for you for $10 apiece, plus $5 to ship them Priority. </p><p><br /></p><p>I've seen people do a lot of hand-hammered coins with this steel without heat-treating the dies at all. The hammer end will mushroom and the die face will begin to sink or "dish"... but you could probably get a hundred or so strikes before it got so bad you'd want to quit. </p><p><br /></p><p>If they're heat-treated they'd last for thousands of strikes. Heat treating means heating them up evenly to about 1550 degrees F, a bright red heat, then quenching them in oil, followed by tempering in an over for a couple hours at 350-400 degrees F. The problem of course is that this is something of a pain to do. I use an electric furnace, which spins my meter at the rate of about 14000 watts while running and it takes about an hour to reach temperature. So I charge $50 to do a run. But these are small and could piggyback in the furnace next time I run dies... which will probably be within a month or two... and then I wouldn't charge you for it... but... I couldn't promise when I'd get them done.[/QUOTE]</p><p><br /></p>
