Gas Forge Burner ?'s
Last winter I had the notion to start blademaking and then got hit with some kind of major flu. Didn't get my stride back till after Christmas and then remodeling projects etc kept me away from blade making all Winter. Being a senior portrait photographer, our busy season starts in April and goes gangbusters thru the Fall.
I've been reading the forums off and on all Summer and now that our busy season is slowing down figured I'd try to build up a gas forge. I did a search thru the site for Trex burners and didn't really find what I'm looking for. Maybe someone can help. Was given a 40lb propane tank aways back to make a gas forge out of. Originally thought about a Whisper Daddy III which would cost a bit more but its ready to go.. The tank size is roughly 16" long by 14.5" wide. When 2" kaowool is added that should bring the ID down to 10". I'd like it to reach welding temps and hopefully there is enough juice to weld up a billet. This forge will also be used for decorative ironwork and large openings will be helpful. Maybe I'll need to block them down a bit for billet welding. Would I need two T-rex burners or just one for this set-up? Was thinking of having the ability to turn off one burner for small stock and run two burners when welding. What other valves should I look for besides ball valves for each burner? Here's my shopping list for now: 2 - Trex burners 2"of Kaowool Satanite over Kaowool ITC-100 over Satanite Needle valve (Not sure what type) Armored hose to 100lb propane tank located outside of the shop for safety. Let me know if there's anything else you may find helpful. thanks for your help, Allen Last edited by Grundsau; 10-27-2005 at 02:44 PM. |

Try this link:
http://www.indiangeorgesknives.com/b...g_a_forge.html IG's forge is a basic air blown burner. I got the chance to see and use them first hand last weekend. They can do anything. We were welding up cable damascus with them all day long. If you build it just as he describes with a hard firebrick floor, flux is not a problem either. He said the last time he refinished one, the floor had 3/4" of flux on it with no damage whatsoever. |

granted i know not that of which i speak, but isnt a 1/8 hole a little big for the gas outlet hole?

Beats me!
Seemed to work pretty flawlessly for forging and welding up damascus, though.... |

I recently built a forced air forge similar to the one pictured above. The outlet in mine is simply a 1" pipe and it works fine too. I think the great thing about forced air forges is that nearly ANYTHING will work as long as the fuel and air get mixed well....

Thanks guys for the replies. Forgot to mention this is going to be a venturi set-up. The ability to keep forging after the power goes off is a definite plus. We often lose electric during the Winter and sometimes during the Summer where we're located.

Take a look at Ron Reils site, alot of different burners. I have built just about all of them, but the improved sidearm burner seems to work the best of the venturri type. With a little engineering this type burner can be used as a forced air, as well as venturri.

Hi Ken, I had printed off all the info to be found from both the Ron Reil and Hybrid Burner websites.
I'd really like to know if 2 - 3/4" T-Rex burners are enough or too much for a 40lb tank to reach welding heat? Someone out there knows the answer. :cool: Thanks anyways for the suggestion. Allen |

In a word yes, but a 1" or 1.25 would do it for you too. I have found that multiple burner venturri burners seem to have problems quite abit.

Talk to Rex Price. He's the one that knows about the T-Rex's. He designed and now makes them.

Thanks again for your help. I had emailed Rex with questions and received no response.
While searching thru Google, I found some info on gas forge kits. For the time (which I don't have a lot of) and effort it will take to locate parts, plus the nagging questions of "am I doing this safely?", these kits have everything and are ready to be built. The forge outlined in red looks like a winner. Quote:

Tiktoc, What does the flex hose do that comes off of the secondary blower? I am guessing that it deflects some of the heat from the front of the forge? Inquiring minds want to know.
