Making a gas forge

[Hawkdancer]

Be sure to open the valve and stand back a ways before creating a .44 magnum vent hole in the bottom! .  I wonder if a 30 lb. bottle would be more versatile as far as being deeper for longer stock?

I started on the burners tonight.  I have them assembled but I still have a little work to do before they are done.  I made temporary air choke plates.  I will make some out of thicker metal.  I need to tack weld the nozzles in place so they stay centered.

That thing looks like it will fly, Clint. I'm sure it will heat up steel.

[KHalverson]

once you get those burners tuned that thing will go to welding heat no problem.
I need to build a new propane forge myself and a new coal forge.

The nozzles are tack welded in place and I could do a proper test run.  They worked great.  I need to figure out a better option for the air choke plates.   I'll do that after I get it all installed.

Them horses is snortin' fire!  Looks ready to put together and do a test run!

Well I'm slowly making progress on this thing.  Tonight I lined it with ceramic insulation wool.  I used 2 layers of 1" thick material.  That is some nasty stuff.  I wore a respirator to avoid breathing the fibers.  The next step is to coat it with refractory cement.   I'll try to get to that this weekend.

That's gonna be a class A gas forge, Clint.

What size hole do you drill for the gas jet?

What size hole do you drill for the gas jet?

I used welding tips for the gas jets.  I think they were 0.6mm. 



I ordered some fumed silica powder last night.  You dissolve it in water and then spray it on the insulation.  It's supposed to harden it and make it easier to line with refractory cement.  I will have to wait a week for that to arrive now.

Great build Clint.

Jack of all trades

Looks cool!  You passed my skill set when you said cutting torch and weld!  That would be a neat sight to see at MoJam, though!  Can hardly wait to see it fired up and working!

I coated the ceramic insulation with the fumed silica.  I put some red food coloring in with the water when I mixed it up.  That way I could see where I had coated it.  I'll give it a couple of days and see if it hardens up like it's supposed to.

Are you going to have a remote igniter? Might save a little knuckle hair. 

[osage outlaw]

No, I'll use a small hand held torch to light it.
