So I'm taking a pipe fitting class, and for final projects we can make a personal project, so I decided to make a coal forge. But we need a blueprint to build it off of. So I was wondering if anyone has blueprints for a small(ish) coal forge, just something that can do knives and other small projects. It would be preferable to have welded construction, other wise just the usual accommodations for a blower, ash dump, etc.
