Hey guys! I've posted and talk about a propane tank enclosed forge me and my dad are building, but now I have some questions about our old brake drum forge we built maybe 4 years ago. It's pretty open, (Check pics) though it holds a decent enough amount of coal. But the problem is that I'm not getting enough heat. It take a long time to heat up the steel, and it's hard to heat up even just a rail road spike to bright orange. So... What can I improve on this forge to fix this? We only have the one pipe at the bottom of the forge for airflow with a little door at the bottom to let out xxxx, and I am using a little electric squirrel cage blower as a bellows. I think it might be possible that the air is hitting the metal, so it cools it off rather then just blowing the fire. I also am getting a lot of small coke and small clinkers down the pipe, but I think just welding a grate over it would fix it. What do you think? What would help? Do I need more airflow, and the airflow spread out more rather then just the one spot? Also, we don't have an anvil but we do have this big 150-200 lb. steel block that's perfect, it just doesn't have a horn. Though, I'm thinking I can just turn a cone on the lathe out of 3"-4" steel bar and weld it on. Would that work do you think?
