[TheForge] Superquench/hardening power hammer dies

[Kevin Dona hoe]

Say Bob,

Thought just occured to me that the demo with superquench is to make a
chisel out of 1/2" stock and quench it and use that as a cold chisel to cut
the parent stock.  The A36 won't have any ability to retain toughness when
heated over and over with hot work... they'd just soften back to regular old
mild steel.

Oh, but if it's just the dovetail/retainer, de'nada

  -Dave and all,
  -
  -First thanks for all the comments.
  -
  -The original question was in reference to hammer dies for the new
  -dovetail die holders I just got from Sid at Little Giant. They are just
  -the dovetail section of the die with two tapped holes for mounting your
  -home made dies. The hole spacing is the same on top and bottom
  -dovetails. About  3-1/2". The dovetail is 1-1/2" thick for both top and
  -bottom.
  -
  -The original LG 25 dies were 3" top to bottom (according to Sid). If
  -you use a 1/2" thick plate to weld your die to that leaves 1" for the
  -die/hammer/anvil thickness. So it's 1-1/2" for the dovetail which stays
  -keyed into your hammer. 1/2" x 4-3/4" for the mounting plate and 1" for
  -the actual die (i am using 2"x3"x1" A36). So this is not really a
  -massive part to quench in a five gallon bucket.
  -
  -First I'm going to try Otto Bacons formula which is just Cascade dish
  -soap and water. If that gives a little hardness...fine. If not I might
  -mix up some super quench and try that. If iI start wearing dies out I
  -will buy some W1 or O1 or etc. Chances are that I will wear out before
  -the dies tho.
  -
  -Happy New Year to All.
  -
  -Bob
