[TheForge] anvil repair

Sat Apr 27 21:52:34 EDT 2013

Jer, we've been doing it this way over 15 years and to my knowledge 
there has not been a single failure.  My 128# wrought anvil was the 
guinea pig and we had at least 4 different rods in it to see which 
worked best including 2 by Stoody, the Hobart, and one other I do not 
recall.  The Hobart was BY FAR the best.  That anvil sat in the shop at 
Allaire village for 2 or 3 years being abused by all the newbies and 
other loons whom I have witnessed do things to anvils and other 
equipment that demands shooting.  The only divot came out of one of the 
Stoody beads.  The rest are immaculate to this day and I have wailed on 
that little anvil a fair bit.  My 106# PW is all Lincore 50 and after 
more than 10 years not the smallest hint of a chip anything along any of 
the still razor sharp edges.

It is difficult to argue with success.
