I bought a portable Hand cranked Champion Forge today from a fellow who said it was a gift to a family member many years ago. It's about30" diameter, looks to be '30's or '40's vintage.. The family was in the business of manufacturing architectual hardware and ornamental hardware, and the forge had an add on conical section with a grill which allowed it to be used as a barbeque. Since it was used only a few times a year for cooking, its in very good condition. I tried it out today, heating up a length of rebar in a couple of minutes. I read online that the tray should be lined with clay, but I see no signs of clay remnants indicating it was used this way in the past. I guess fire clay a 1/2" inch thick or so? What was the main application for these forges when they were new - horseshoeing? Should charcoal, coal or coke be used for fuel? Anyone have one of these forges?
