This is a step by step guide to making a sturdy tripod you can use to hang a cook pot, dutch oven, coffee pot, or anything else you want to hold over a campfire.
There are very nice commercially produced tripods available, including expensive wrought-iron ones. This one can be made for $20-$25 if you buy everything brand new, and will be nearly as durable, and certainly lighter. It could be made cheaper, even free if you can scavenge the parts from scrap. (Update - I just saw a wrought-iron one at Joe's sporting goods for $45. I think I'll stick with my conduit one.)
