So after my damascus experiment it became apparent that my coated perlite refractory wasn't up to the task to forge welding.... It melted. So I decided to not bother trying to bandaid it again and went ahead with my new forge build. Hmm... something seems... off. Your forge body is supposed to get red hot right? So I got to work with the angle grinder and welder (a super useful addition to my shop even if I am pretty much the world's crappiest welder) and cut up the 30lb propane tank I had acquired for this project. But before I could do some of the cutting I needed to know where to put the burner holes. Side project time... Double burners. Quite a bit of cutting and welding and drilling and tapping later I had this: And now I needed to line it. I'm using a ceramic blanket for insulation, I believe it's rated at 2600 degrees and I doubled it up for two 1" layers except for the bottom where I'm planning on using replaceable hard firebrick so I can easily swap it out when it degrades. Initial firing. It's ALIVE! This is running at about 5PSI and the back burner likes to try and go out so I suspect I'll need to run this at a bit more pressure than I used to with a single burner, but so far seems to be working. I still need to get some 1/4" plate to make front and back tables so I can adjust the size of the openings but only had some thin stuff or way thicker stuff in the shop at the moment so that will have to wait for a bit.
