thanks for the warm welcome. the forge(the hole) is about 4'x2'x18' about 140 inches cubed. the burner is a normal blow torch (has a small nozzle and a nickel cylinder thingie 1 1/4' wide) that can melt thin plates of aluminum but still not enough to weld steel apparently. as for gas i use a propane tank which i keep at the pressure of 1 bar which heats the forge in no time.

i have been watching these forums for months now and i decided to finally say hi. i built a propane gas forge sometime around January, bought around 40 fire bricks, a gas hose, brass clips and rivets, and a 1 1/4" burner, and a bag of high heat cement (which i still haven't used ). i found i loose a lot of heat because of the lack of insulation but the burner keeps up nicely (2-3min for a good temperature) but i never managed to weld (my steel never went over the bright orange almost yellow) and im looking for tips to manage to welding temps. -So do i need another burner? -do i really need to cement the forge (but that way i will loose the ability to change the shape of the forge if i need to make smaller or bigger projects) -if i have to cement it will it be better if i cement the center in a circular shape or just beep it a box shape thanks for your patience reading all this stuff regards :D
