  1. The guys in that video are gonna get hurt! They are striking a chipped ball peen. Just a matter of time before they shatter one of those hammers and take shrapnel in the leg. They might wanna heat the metal to a forging heat as well. I like the home made anvils though.

  2. I was just referring to burner placement and articulation. The burner body (intake tube with bell) should not get hot. It is drawing air for combustion into the forge along with the fuel. This mixture is combusting maybe an inch into the forge and creating the jet-like flame. My forge burners stay so cool you can put your hand on them and they are barely warm.
    You can plasma cut and roll your tubes, i was just stating that you should make sure and keep everything smooth. Aerodynamic is the key to an efficient design. If you have a jagged tube it will create turbulence and your flame will be all over the place. Good luck. Just remember that it needs air to combust properly.

  3. The whole idea behind the burner designs you are trying to create is efficiency. You could make one, but if you bend one yourself, with a bell, and its not smooth, there will be turbulence and the burner will be noisy and erratic. Some guys use a choke atop the bell to create the different flame characteristics. Plumbing parts are cheap, and i would think bending and welding your burner would be way more trouble than its worth. As for burner placement, i have seen both angled burners that help create the swirl effect, and like my own gasser, pipes straight down from the top center. Mine throws the flames straight down onto the refractory firebrick in the bottom of my forge, it is a diamondback two burner blacksmith model.
    I am really impressed with the patience displayed by fellow members in this thread.

  4. Dothacker, Ever heard of google? check out forge designs, you might decide that the design you chose may be an exercise in futility. Google Larry Zoeller forge, he has lots of great info on burners and forge building. You can also check out blacksmithing supply, it seems to me that there is a good reason most gas forges are similar in design, thats because they work.

  5. it wasn't a complaint. Perhaps if you had posted what you were trying to do and with what hardware you wanted to accomplish this, you might have received info to your liking. Sounds like you are asking for help and frustrated with the answer. What you are attempting to make might work to heat metal, but won't be very efficient. Most of the forge designs i have seen have the burners aimed at an angle through the top. these are burners designed to suck air into the forge with them. If you just stick a propane torch through a hole and close the door on that box, it wont have any air to properly combust. If you look at the gas forge section on this site, you can find info on making your own burner, and it is pretty cheap.

  6. Um, refractory is needed. Depending on the burner used, you will most likely heat that box so hot it will deform with no refractory lining it. Depends on what you are trying to do. Even with refractory, i placed my diamondback two burner gasser on my 1/4 inch steel welding table and it heated the table so hot, it bowed in the middle. And thats with a full lining of refractory.
