[TheForge] Fw: Anvil repair

[Bob Willman]

	I still have the BBQ photos somewhere in my files.
Also the attempted anvil repair that went sour some years back.

Might you have mixed up the order of the ingredients in the sandwich?

If you put the carefully milled face on a carefully milled body and put a
layer of sheet explosive on *top*, covered with some kind of heavy
felt/sandbag/whatever matting, and fire off the sheet, you can get a
full-surface weld.  I assume that to get good, reproducible results would
take some care and experimentation.

I looked into doing something like this once but the regulatory horseshit
made it more trouble than it was worth.  I tried to find out how an artist
in AZ (or TX? I forget) managed to do a bunch of explosive-formed pieces
without getting mired in the regulatory crap. She didn't tell me so herself
but I eventally learned that she had political connections --
daughter-in-law of the governor or some such -- and they just cut her as
much slack as she wanted.

BTW, about that thermite-roasted goose:  I thought real blacksmiths did
their Christmas geese with a barbecue onto which they poured a bucket of
lox.  (Anybody know where there are any pics still on the net of George
Goble's lox barbecue? After Purdue asked him to remove his site, there were
still some at ep.llnl.gov/msds/Chem120/lox-oxidation.html
but ep.llnl.gov no longer resolves.)
