Basically, brake drums make horrible forges if fitted with legs and used with no table (the famous INTERNET brake drum forge design), but if you cut a hole in some heavy plate, supported in a sturdy angle iron stand or something similar and drop in the brake drum to use as the fire-pot, you have an EXCELLENT forge. If constructed well, fitted with a nice ash dump and possibly even clinker breaker design and fed with a proper air supply with sufficient volume, this forge will work every bit as well as one with a commercial fire-pot. And with proper scrounging can be made for FREE or very little $$$$. Chris.
