I make a little brick cubby and use a propane torch. I had a forge for the first 10-15 years here in the suburbs with a yard 75 feet wide. Neighbors not enjoying it. Reporting fires and whatnot when I was coking coal.
We are hoping to relocate next spring/summer to Vermont, get some land, outbuildings before I’m too old to set up the forge. Have a good sized anvil, fine swage block, leg vise, lots of hammers, tongs, hardy tools.
