<p>[QUOTE=&quot;Drusus, post: 663564, member: 6370&quot;]Thanks, it may take a few months to get everything ready. I have steel dies but decided to go with a different type (mine are tall and thin, I want the shorter and wider to make it easier to strike) so I need to get they right steel bar at the right thickness and height. I need to get a Kodalith made of the design and then I need to see if the photoresist I bought is exact enough to transfer the detail.</p><p>&nbsp;</p><p>This photoresist is a way to chemically etch metal and some types are so exact one can etch almost microscopic letters. I will expose the resist through a kodalith mask with UV light then develop it. This should leave a coated resist area and a non-coated area, the non-coated will be where the acid will etch. I will use a nitric acid mixture to etch. </p><p>&nbsp;</p><p>If the resist I bought is not exact enough I will have to get a different kind. Its a learning process but I might be on the right track. I am doing this in my spare time with little money so its slow going but I am trying to get a process down. I just need to get all the steps right once and then I can always repeat it.[/QUOTE]</p><p><br /></p>
