Well i started building a forge about a month ago and fired up for the first time today. Built it out of a old grill body to hold everything, then fire bricks and a brake rotor for a pot. ran air in underneath with steel pipe. Fired it up using royal oak. Then started practicing on some cold roll steel. Apparently, the grill body wasn't the best choice. i burnt through it in about 45 mins. So i let it cool down and started over. Since i live in ga. (red clay capital of the world), i buried the pipe and dug the brake rotor in to the ground and bricked it up for insulation. I'm also apparently having a problem regulating my heat. I melted my metal. I was just trying to beat out a round into a flat and break everything in. Then decided to fold it over and try a weld. Got it to weld twice, folded it again (practicing for knives) and put it back in the fire. The next time i pulled it out to hammer, it was just about burnt through. Also generating alot of scale. Any ideas on this????
