Swede, Mikey, Frosty, thank you for getting back to me so fast and for the welcome. I will try to answer all of the questions in order:
The burner was in fact outside of the forge container, as it is still drying, and I am also still mulling over what angle to have the burner inserted (I left out making the hole, as it can be easily added, the forge vessel being made of 2600 rated IFB).
It definitely makes sense that it would run differently inside the forge; I suppose what I was looking to do was try to see if I was getting a good looking flame. Also I was just really excited to fire it up, ha ha.
If it helps, I was following the parts list from this video (save the other bits with patina; those are reused from my first burner, which was a gas hog and way too big for my new forge): https://youtu.be/dXFcwheId9I
I will give it another shot, this time in the forge, before I try adjusting anything. I ought to expand on the reason I mentioned prior for the burner not being inserted into the forge yet. As I said, I am having trouble making up my mind on the angle.
This is the forge I cobbled together. I did not feel comfortable handling ceramic wool, so I went with IFB instead. I am on a bit of a budget, so I tried to stretch 4 2600 degree rated bricks as far as I could. The sort of jigsaw looking fit is what was used in the final build. I had one 2300 degree brick left over from my first forge, so I used it to add more insulation in the corners; I figured being away from the actual hot interior, their lower rating and relative fragility wouldn't be too big an issue. You can see in the photo that I ended up with something a little different than the drawing. I decided that I wanted something to put in the front and back of the opening of the forge, so I saved half of that 2300 brick for that purpose, rather than sawing it into quarters like I had planned. I wanted to keep at least 2.5" of insulative material at all angles though, so I used the sawed-off rods of the 2600 degree IFB I was left with after cutting the joints into the brick. They weren't quite tall enough, which explains why it looks like an adobe building instead of a box.
I ended up mixing way too much satanite. After everything was together, and not wanting to waste it, I just kind of... slathered it on the outside. Trying to offer as much structural integrity as I could, remembering how my previous forge of 2300 IFB crumbled to bits after a summer of use. I'm sure this will do little to stop this one from meeting the same fate, and the whole mess will probably serve no other purpose than being a big heat sink and flake right off... But it at least makes me *feel* better, ha ha.
But enough of my justifications for what is probably a poor build. Like I was saying, I am unsure of what angle to go with inserting this thing. The pencil in the photo shows my current thinking. Trying to bounce the flame off the roof, onto the left wall, and hopefully spiraling to evenly heat the forge. In theory. The internal volume of this thing is so small, I don't know what will happen. But as long as it can make stock removal blades hot enough to quench, that is all I need it to do.
I didn't mean to write an essay, but my fingers got away from me. In short, I plan to take all of your advice, and try running the burner again in the forge at a higher PSI as Frosty mentioned. To that end, am I on the right track with the angle I had planned? Is the tiny internal volume of this little monstrosity going to cause headaches?
Thank you all in advance, I really appreciate it. I have a friend getting married in late August, and I promised the happy couple a chef's knife as a wedding present.
EDIT/P . S . : I forgot to mention, Frosty, I am in the CNY/Upstate NY area.
