Making a gas forge

[BowEd]

Pretty blame neat Clint!!Now how hot is it going to get in there?2000 degrees or better?

[osage outlaw]

I'm not sure Ed.  I'm hoping it gets hot enough for forge welding.

That is looking very good Clint.

The rigidizer took longer than expected to dry because the temperature dropped.  I put a space heater blowing through it for 24 hours and that dried it out.  I put the first coat of Kast-O-lite over the insulation.  It's a castable refractory cement.  I bought 15 lbs of this stuff and used about 6 lbs so far on the base coat.

Just a little tip, you should remove the feet on your forge and re-weld them so that your torches are straight up and down. Your torches come in at a 1:30 position and blow to a 7:30 position that means your heat goes that way also your going to want your heat right in the center where your metal is gong to be sitting you will save gas and heat your metal faster.

I was told to have them come in at an angle like that to get the heat swirling around the chamber.

looks good with the refractory cement.
it should keep the inswool stabilized very well.
if your gonna forge weld ya might wanna put a hard fire brick in the bottom as a sacrificial floor.
flux will break down some refractory materials.

I will have extra refractory left over.  I was going to build some forms and make a few bricks from it to use as a replaceable floor.  I'm going to do a second coat of refractory and then the IR reflective coating.

I did a second layer of the refractory cement today.  I added extra to the bottom to make a flat surface.  I will need to let it dry out for a good while before moving on to the final step.  It's almost finished.  I have 4 lbs of refractory left.  I should be able to make several bricks for the bottom.

that looks really good!
im watching this with anticipation cause I need to build a new forge.

I ran out of propane trying to go through the curing steps the other day.  I got a new tank and started again today.  This thing will put out some serious heat.  I need to do another heat tomorrow and then it's ready for the IR coating.  That is the last step. 






After shutting it off the inside glows




I took some of the left over refractory and made a brick to put in the bottom of the forge.

Here is a short video of it running.

Clint, you better bolt that thing to the workbench. Looks like it will heat something up in no time...and heat your shop.

[osage outlaw]

I need to tune it down a little Pat.  I had the regulator wide open.
