This is my big forge... 26" long, three burners, and it eats up propane fast! A 20LB bottle will freeze up in about an hour. This one was created specifically for making swords, but it will handle anything up to 3.5" in height and 8" wide.
 
On the sides you can see an entryway made up of 3/8" steel. This keeps the flames a little further away from the thin sheetmetal from which the barrel is made. As you can see, there is still a lot of heat washing over the sides, and the paint has been burned away.
