I am not trying to discourage you, but I don't think there would be enough
widespread interest in anvils to make it cost efficient as a business
endeavor.  However, if you want to do it as a labor of love, then more power
to you!

My vote for a design is a 2 horned anvil, one square and one round in cross
section.  Long, finely tapered horns are better than short, blunt ones.
 Weight would be 150 to 250 lbs. - bigger would likely be too expensive.
 Hardy at 1" and pritchel at 1/2".  As far as material, 4140 or similar would
work.  I believe there are also some new die steels used in the auto industry
which will air harden to 60 Rc with local torch heat, but they are probably
very pricey.  You can flame harden the surface of 4140 with any of several
industrial techniques.  Fisher anvils were cast and then chilled to harden
the face.  Supposedly this was a proprietary process at the time, but you
might be able to duplicate it now that patents have expired.  I had a Fisher
and it was a great anvil, but it didn't ring like a wrought anvil.  This did
not detract from its utility.

Good luck               hollis

If you decide to make anvils, then an attractive cost would be $2.00 per pound.
(Less than $2 would be even better but is unrealistic.) If you decide to do
this, drop me a line. I would be interested.

	It would be the latter, by all means.

	C60?  Is that not a bit too hard for the face?  I'm asking out
	of ignorance.  I thought maybe more like C55-57, but as I said
	I don't know about this.

	Assuming C60, I was thinking perhaps it would be good to draw
	down the temper on the corners to perhaps 55 so they won't
	chip too easily.  They might round off a bit but I think that's
	preferable to hard, sharp edges and stress cracks that could
	propagate with continued pounding.  The rounded edges would work
	harden over time, hopefully with a relatively small radius.

	Thanks.
