|    Struck Coin Blanks ???    |
|    27 Nov 24 13:57:58    |
      From: none@none.com99              Every since watching a woman dressed in pirate garb at a renaissance       fair (or faire if you prefer) place a blank in a set of dies and drop a       heavy weight on it to strike a souvenir coin I have had in the back of       my mind the idea to strike my own coins. I can certainly make the dies.        4140 is relatively easy to machine if you know how, and it will harden       "hard enough" for a low production number of from a few hundred to a       couple thousand coins. I also keep a bit of O1 and W1 on hand for those       cutting tools I can't hand grind from HSS or carbide. I even have a       propane forge in the back along with a toaster oven for tempering       (although it gets used more for powder coating).              I started writing with two questions in mind.              Where to buy/make coin blanks at the best price? Not the 10-20 on Ebay       or Amazon, but a couple hundred to a couple thousand at a more       reasonable bulk price.              I forgot the other question, so my second question is what question (or       questions) did I forget to ask? Maybe what alloy would best? I suspect       an annealed copper alloy of some kind. Many an amusement facility used       to have a machine that would take your penny (and a dollar) and roll       your penny into a souvenir key tag back in the days when pennies were       still copper.                                   --       Bob La Londe       CNC Molds N Stuff                     --       This email has been checked for viruses by AVG antivirus software.       www.avg.com              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
