Not far from me is a steel foundry. I called a few days back to ask if they had ever cast anvil. The person I talked to in sales said they had not to her knowledge, but would be interested.
The questions as asked,
Would it need to below carbon, or high carbon?
What steel composition was I considering?
What volume of steel would it require? (This question regarded to price quotes)
So, if you could have a custom cast anvil, what would you choose?
What features would you have and why?
