[TheForge] To ring or not to ring[was anvil i d]

[Mike Porter]

Thanks Walt,
Now I can buy a cheap little (jeweler's size) Harbor Freight cast iron anvil
and do some experiments to find out if their full size door stops can be
rehabilitated by urban novices into a reasonable first anvil (an anvil's
thud plus rebound would be music to urban ears, especially if it only takes
some heating and quenching.

Thanks also to Hochewa for the enlightening description of his own cast iron
anvil. Considering the ease with which iron can be cast from home-built
cupola furnaces, the Australians at the very least should be interested in
this subject.

Mikey,

Chilled faces were developed by James Oliver for improving cast plow shares.
>From the following site: "A chill is a metal mold or portion of a mold in
which molten metal is cooled rapidly and the surface of the metal is
hardened. By using an iron "chill" in a portion of the sand mold, Oliver
produced a hard surface on the cast- iron plowshare, the cutting edge of the
plow blade. The resulting plowshare retained its sharp cutting edge much
better than traditional plows, and the cast iron was less brittle than usual
because the interior portion of the iron cooled slowly."

Cast iron can be very hard, but I don't understand the term "chilled face."
Could you please explain it?

To All,
I have two types of anvils; ones that are steel and ones that are cast
iron. 
 The steel ones ring like a bell, so to speak and the iron ones  don't.  The
cast iron ones that are gray iron all the way through, i.e.,  cheap, are
dead and lifeless.  I have one with a chilled face that is  harder than any
of my steel anvils and has an excellent rebound even though it  goes thud
when you hit it.  Striking on the horn does make a feeble  ring.
They all have their own personalities.
 
Hochewa
