It works! It needs a few modifications but I've already burned the you know what out of two of my fingers! Now where's that aloe plant!

Guy,
Forge looks fantastic. Is there any chance of
getting you to e-mail me directions to make one myself. As I currently drive 700 kilometres when I need to make my blades This information would be great if possible.
Regards
Steve
 
Say, that's slick! What do you run in on, a barbeque tank? Here's a tip I learned for running small burners from 20 lb propane tanks. As the gas runs out these tanks will freeze up. Setting the tank into a container of water will prevent this and let you get right down to the bottom with less freezing up.

I'm about to construct something similar so I 'm interested in the details as well.

Thanks for the tip Peter, the burner seems very economical, I have used it many times as an open air burner for spot heats on various things and have yet to get to the end of the first barbecue tank of propane so I'll watch out for the freezing.

G2, it would be very hard for me to estimate how long it took me to make. I've been working on it for months, an hour here, an hour there. I generally work quite a bit of overtime and have a young family so I try not to totally immerse myself in this stuff every spare minute I have, though who knows how much cumulative time I've spent on these forums!

General specs: Made from a freon tank with two 1" layers of 2700 degrees kaowool coated with ITC-100, which is a ceramic heat blocker that acts as an extra inch of insulation. The burner is a venturi design made from off the shelf plumbing parts and works amazingly efficiently.

It seems to heat up to forging temp in 5 minutes or so and heated the last four inches of 1/2" rod to forging temperature in nothing flat at around 2 or 3 p.s.i. With luck it will forge weld at around 5 or 6 p.s.i. Oh, don't use a barbecue regulator, get a good red top regulator rated at 0-15 or so.

Good Job, Guy!
Three of us in the local area built the same forges. One is being used, one was completed tonight and one is still in process. These are real gems!
I see that you mounted your gauge up on the top of the burner. Is that where your line from the regulator enters the burner? I have mine on the tank, and the way your is looks like it would be easier to read.
Again, good job!

Dave, it has been suggested to me that I'd probably get more accurate pressure readings if I had attached the pressure gauge to the regulator itself. It just seemed to me that pressure should be the same througout the system from the regulator to the burner. I'll have to get another gauge and install it on the regulator also to see if this is the case. -Guy
 
Going to let us know when you've tried welding in it?

That is Awsome !!!!!!!!
Mine used to look like a pretty new one also but now after years of hard use it looks like it threw up all over itself or is just boiling over I don't know.I do know that it is the ugliest forge that I have ever seen,but it works...

No. The first gives me the tank pressure and the second gives me the regulated pressure. It's just like an air compressor.
