will this work?

If that's a weed burner torch (HF?), yes. Wayne Goddard responded to a reader's question about same in Blade, a few issues ago. I forget all the details, but supposedly it would work, although there were a few modifications necessary.
 
Micheal: I don't know for a burner, but that sucker puts out some BTU's. I was burning weeds in my backyard, behind my neighbors garage and it was popping pieces out of her cement blocks. I don't think the tip will last long, but it sure will heat up the forge.
 
Yeah tried one.
Those things are made for burning weeds 20 feet away.Had a 2 foot piece of 8inch pipe; stuck the burner in one end and had flames coming out the other 5 feet or better.if you try to cap the end of the forge with a brick or something the burner gets way to hot.
Maybe you could hang the thing from a tree and hold the knife under it??

Thanks guys, just curious!!!! I bought all the parts to make burner, just gotta put it together.
 
On my way south from Atlanta I stoped at Bill Sowell's shop. One thing he said was that a naturally asperiated forge takes lots more gas than a blower driven one. Being the second cheapest person in the world I took notice.

Michael, I built a weed burner similar to that one. I have used that burner with a piece of kawool to anneal a 42 saw blade.

I don't believe you can make blanket statements about blower vs. venturi forges. The venturi I built will weld on 9-10 psi., and forge about 4-5 psi. The blown forge i built used a lot more gas and produced a lot more scale.

The little venturi I have now, about the size of a freon tank, does all the bladesmithing I get to do at this point.

I have a Don Fogg style in the works that will be strictly for welding. It will be a venturi style also, unless it doesn't work;)
 
Hey MikeS, my freon tank forge with a venturi burner also seems to run very economically and I also forge at around 4-5 lbs. psi. I haven't tried to weld in it though I am certain it will reach welding temps with no problem. How do you protect yours from flux (that's the main reason I haven't welded in mine yet)? Like you I also have a Don Fogg style verticle forge for welding in the works, but it will be a while before I get it done.

What kind of burner are you building Michael?

Guy and others-

I HIGHLY recommend you don't weld in your small forge. I used my freon tank forge and the borax just ate the heck out of it. I got lucky...I was able to tear the shelf out of it, chisel off all of the borax, flip the shelf over, and put it back together clean as new. And I did very little welding in that little one. A few more times and it would have eaten through the shelf.

Wait till you have your vertical forge done to weld. Or build a small one like you've got with no floor and lots of room for kitty litter...

My forced air castable refractory forge uses 2 psi to easily weld, one to forge. Takes about 10 minutes to get the thermal mass up to heat. I've recently done billets as large as 2"x1.5"x9". That's a lot for my flabby arms to do by hand.
 
Mike, I have a similar torch at home, similar except it is cast iron. My wife used it to fire a small ceramics kiln made of KAOWOOL for a couple of years. 'worked great, and it is hanging there waiting for me to put together a gas forge someday. There is a lot of cross over between the potters and their Kilns and various fuels and materials, and the forge thing. I encourage anyone interested in building a gas forge to do some research in their local library for books on building ceramic kilns. Lots of good info out there about refractories etc.
 
I have one of those. I tried it hooked up straight to the propane tank. Nearly fried my self and the trees in the back yard!
It will work but you need to put a pressure regulator on it. The type for a BBQ should work along with a control valve to regulate the gas flow. It puts out some heat just needs to controlled. The Venturi on the front works very well.
