Trying to cobble together stuff to get started - picked up a free grill I have plans to line and turn into a forge, and today I picked up a stump from down the street that I hope to use for a starter anvil after smoothing it out a little. My question is - can I bolt down a piece of steel and bang on this? If so, what kind of steel would be best? I'm thinking a piece of 1/4" steel, maybe 3"x18" depending on what I can get on the cheap. I'd like to find a piece of RR track but haven't had any luck so far. Any advice is appreciated.
