Really nice furnace! I do some home metal casting - a bunch of ridge tiles is a great idea.
I am a bit surprised that railway track has enough carbon in it to harden just with a quench. Did you use anything to encourage it to case-harden when you heated it - charcoal in the furnace, or suchlike?
What a great job! And that is a pretty powerful torch too. I have been sitting on a 6' chunk of rail for years but chickened out when I found a 106 pounder for $100US! Impressive anvil! Bill in Boulder CO USA
Hi, Celso. I also made a railroad anvil, but the hardie hole is difficult to make, due to the hardness of the steel. It was not tempered, but worked as it is. Drills don´t work well, How did you made that perfect square? Muito obrigado.
