[TheForge] Preheat your anvil

[robert hensarling]

My PW weighs 497.  Ralph Sproul suggested that I pre-heat to 200-300 before 
starting to weld, which I did using Oxygen/Acetylene torch.  Took about 30 
minutes to get to 300.  I used an digital temp meter to monitor the temp. 
After I finished welding, I placed a plywood box around the anvil (it was on 
the floor, and the plywood box had no bottom.)  I then poured all of the 
vermiculite I had into the box, and covered that with kaowool.  The next 
day, I vacuumed the vermiculite out of the box so I could reuse it again, 
and that anvil was still around 180 or so.
It came out really nice.  The grinding is rough on someone like me, but you 
get used to it.  I think I ground on that anvil for over 12 hours off and 
on.  It came out beautiful!  Thanks Ralph.
