So I assume this has been covered 100 times before, but hear me out: I recently built a Frosty T burner. (And it works pretty well) I had planned to make a gas forge with kaowool and a propane tank, but I learned the extent of the dangers of kaowool. (I already knew it was bad but not this bad) I know there are refractory sealants to protect me from the fumes but I don't want to take that risk. So I want to build a gas forge with firebricks. The issue is: how do I build a stable firebrick forge without welding (and with a low budget) I still don't have access to a welder. I've looked around a lot for info on this and I've found nothing. (Loads more time than an hour this time BTW...) If I made a forge would the brick would I need refractory cement to seal it? Do I even need to support the bricks to make a stable forge? And what type of bricks do I use: soft or hard?
Made my first forge from a semi brake drum ... after using it w charcoal for a few weeks I'm realizing the "fire pot" is way too big and wasting a lot of fuel. I know this isnt exactly a revelation but I'm not ready to ditch it yet so trying to make the thing as efficient as possible ... So far I've tried building up 2 sides w furnace cement (a waste of time and money) it never really cured properly and what did harden has already chipped off. I tried inserting a couple of pieces of 12ga sheet metal to form a more V shaped fire pot - in principal it seemed to do what I was after ... concentrate the fuel closer to the work piece but with nothing behind the sheet to insulate it I'd think I'm losing a lot of heat. My questions ... is there any real drawback to using just the sheet metal? What's involved in placing fire bricks ... can i just place them in there or would I need to cement them to the sides of drum? What about putting a few regular bricks on two sides? And finally, I've read a bit about using clay to insulate - can I build up a clay lining on two sides. Pics attached for reference ... thanks in advance for comments / thoughts
