I Forge Iron

1 Burner forge build advice

Recommended Posts

I had some students over a couple of Sundays ago, and we had just enough gas in the tanks to get the forge close to working heat. I then switched over the tank from the oxypropane torch, which gave us enough forge time to just barely finish the lesson. We make do with what we have!

Gee, Imagine THAT! Join the club Ryan, the craft is full of recurring little mysteries like that. It'll really get to you when you're standing there tapping the gauge wondering why it's going down as you open the regulator . .  20 years from now. Then you get to groan, slap your forehead and promise yourself you'll remember next time. . . Right.

Its been a fun hobby to get into.

First we built a forge but the burner was terrible. So we built a burner but the forge was terrible. So I built a better forge properly. Today I couldnt get the burner to light because I was starting it too high pressure. Then I fix the burner and figure out the best method and boom I run out of propane.

Wow, Wasilla isn't as far out in the sticks as I thought! I can get my 100lb. filled at two places within about 5 miles but the best prices are closed Sunday. Those are Fisher Fuel and Petrolane, here almost in Wasilla AK.

You may have more folks using propane for their houses than we do.  When we moved in there was an electric kitchen range.  I finally talked my wife into stop complaining about it and buying a propane range and then finally talked her into buying a NEW propane kitchen range with no pilots.  She decided on the upgrade to a large tank and delivered propane on her own. (I got the nearly full 100# tank we had previously used for cooking for use in the shop!)

Propane is everywhere up here, even in the bush. Used propane tanks for next to nothing is the norm for yard, garage, etc. sales. If you take them to be tilled at one of the distributors rather than a gas station they just exchange them. The only time I have to wait to get a tank filled is my 100lb.ers. They exchange them so every full tank leaving their yard has a current certification stamp on it.

Propane tanks and filling stations are more common here than snow shoes.

Your pardon; I had mixed your thread up with another one...old age, tsk, tsk.

My burners and all of the other speed burner designs I've played with, differ  by size at their bottom and top ranges, but run very similar through most of their turn-down ranges. So, tarting out between 15 and 20 PSI is always a safe bet. Afterward, play around in the low and high ranges beyond it, mostly just for familiarity.

The gas orifice sizes in high-speed burners (even high speed linear burners) are dependent on the inside diameter of the mixing tube. I used MIG contact tips for .023" welding wire for 3/4" burner sizes. Nowadays there are tips for .025" welding wire that are more appropriate.

What size are your burners?

I have 1, 3/4 burner with I believe a .030 contact tip. Im not entirely sure because I didn't make that section of the burner and the only record I have is a scratch pad with it written on it. 

Ive only ever ran it 4-8 psi. I just got more propane today so im going to raise it up and see how it changes.
