I know I'm probably like the hundredth post about building my first forge, but here I am following suit.
Firstly, it was my first time using a mig welder and didn't know that you use it as any other welder, whoops
Secondly, I haven't done the most research because I'm on a time crunch for Christmas, but i have done some thanks a lot to your site and Youtube.
Thirdly, I'm very close to being broke so hopefully any major adjustments aren't needed.
Fourthly, I'm grateful for any and all responses and advice.
My forge doesn't get hot enough, like not even to where the metal gets a little glowing, just turns them black and kinda blue after 30 minutes. It will get kind of red hot if i hold a piece of steel outside the opening. If i close the opening with that loose fire brick it will snuff the burner out, but i will still get flames that will shoot out of the air holes in the burner (not safe).
It's a propane burner from Harbor Freight, I don't have a regulator on it, and i never adjusted any tip or anything like that. They are hard fire bricks from Menards 9 x 4.5 x 1.25. I already had to use some J. B. Weld on the top and sides where a ton of flames were escaping. I also don't have a bottom plate only a bar welded in the middle to hold the bricks in place. I think the problem I had is i tried a few too many different methods and combined them and threw out the hard and/or expensive parts.
I'm just trying to heat treat knives that I cut from pieces of weldable steel, yeah i know i cheated. I've seen the posts where everyone suggests those kaowool blankets so that'll be my next step, but should i put them inside or outside or both?
tl;dr - I don't know what I'm doing, please help me, I'm broke, too far along, and Christmas is in 13 days.
