thanks for the replies, and some helpfull info..
i'm making one brick forge or two anyway, so probably the i don't need a big torch for now.. this set up just to get me started.. and probably if i'm quite liking it i would expand to a bigger set up.. and i'm still got my option open for charcoal forge, since i just found out that there's a charcoal supply nearby..
i got this website "hybridburners.com" the models here are quite simple yet sufficient for the job, and it doesnt need the blower.. and somehow there's a burner diagram/plan, so you could make it one by yourself..
however since i dont have enough tools, probably making it is not a good option
have you guys have any experience with it??
forging1 = i'm still willing to buy the torch if you're still selling.. just pm me
