    Nice Job on the dies. Some questions:

    Do you do your own stippling?
    What material did you use for the dies?
    Do you heat treat?
    Have you made dies before and how have they held up under use?

    Thanks.

    Do you do your own stippling? Yes, I did it with an airsaw and sharpened the blade, that was before hardening.
    What material did you use for the dies? A2 Tool Steel
    Do you heat treat? I had them hardened to 52 Rockwell ( that was what the original dies were) cost about $100 for the heat treatment
    Have you made dies before and how have they held up under use? I have not made dies before and just finished them last week but am working with aircraft aluminum so haven't really stessed them too much.

    Hi Brian and Steve!

    neat stuff! I need to make a set of shrinkers for my Marchant 6f, so I'm almost all ears....<grin> Brian, you dimpled the face? stipple is a electro-deposit of a harden material. I doubt if the metal knows the difference. Thanks for sharing how you did it, I'm sure I'll have more questions! Now have you guy heard of the new MSA forum, http://metalshapers.org/roundtable/index.php It's a Vbulletin version, this old software has seen better day 10 years ago! Still is link to the yahoogroup. It is 2011 already join MSA on Facebook here http://www.facebook.com/groups/259015644111362/ Take care! tt

    Terry,

    Thanks for the link to the new site. I registered, but waiting for confirm from admin. I saw Barry asking about spray application for stippling. I think most guys use Rocklinizer to deposit stippling. Terry might know more about this than me. I've seen a couple of the machines at auction, but haven't bitten yet. Too many tools and no useable shop + no $$.

    Using saw to gouge face of dies is an interesting way to do it, but probably wouldn't work for restipple unless you anneal and re harden after the operation.

    Interesting stuff. Would be interested in hearing how the saw gouged faces hold up over time shrinking steel.

    Terry, what is the story on the big Dielelt Eisenhardt bracket hammer pictures? I saw the same pictures in Tim Barton's book. Who owns it?

    Take care,

    Steve Kadisak

    Stippling: rocklinizer is the commercial made one, John B made a power supply and used a electrolytic bath rubber gloves and jacob's ladder for ambiance.....

    D&E hammer well I remembered TC Terry Cowan talking about and how excited he was to get it, I had never seen it. I don't even know how the topic came up out of the blue I remembered Stan Carter had it, we are talking a couple of years between thoughts of the hammer. Somewhere in those years I came up with an ad in a newspaper or book, but I have know idea what happened to that after I sent it to TC. There were so many things TC and I were interested in we always sent stuff almost daily back-n-forth. I know he was always asking about an Edward Ewheel in StL. that was for sale cause he had a line or had one bought in Europe.

    Tim has got to get all the books out cause I want a signed set!!! I had #2 with me today, the Roll-a-ball I love it!!!

    When I was in Tech School so many years ago. Machinist program had an EDM machine that could also put the same texture on the die even in the hardened state. I don't know about you but the shrinking dies I have on my Marchand are the ones I got with the machine several years ago and they are still fine. I would have to do a lot of shrinking to wear them out.
