[TheForge] chinese ASOs

I like my solution but then again.....
I have several kids I am teaching to as I call it abuse hot metal.  They
work on those cheap cast steel Chinese anvils.  To make them feasible I took
a piece of nitride steel, bored holes in the anvil and turned pins in the
lathe of the same nitride steel, there were an interference fit for the
holes of like .007, I put the anvils in my cooling oven and heated them to
450 degree's froze the pins in liquid nitrogen then took the 40 ton press,
and pushed them through the holes until the tapered heads hit the tapered
holes in the top of the nitride steel plate, we then tig welded the pins to
the top plates with a fusion weld, and flycut them in the mill to a nice
surface.

Total in 5 anvils we had 3 hours work, and 50 dollars in materials.  They
have probably 200 hours of abuse on them and seem to be holding up fine.
Basically we got 5 about 200 pound anvils for around 500.00 or so.
