It looks pretty much identical to what was in the original video, so if you didn't see anything wrong there, we should be good! 

I'm also curious about the blue dragon's breath. Never seen it personally, but if it's bad I'd like to know how to fix it. 

It's definitely putting out plenty of heat, and I don't think any scale is forming until I pull it from the forge. It's very possible I'm just overly jumpy after having so many issues getting to this point 

Mikey, if you're talking about any dragon's breath, I'm pretty sure it's all nice and yellow! 

Not yet, I'm just going by the sound and what I'm seeing. The only time I've heard a similar sound is a few videos I've watched where that was the issue, and I can see the flame moving up into the hole I have in the refractory. 

Alright gentlemen, not sure if it's a new problem or a continuation of the old one somehow, but I think the flame is burning back up the pipe a little bit. I'm getting similar results without the fluttering sounds. 

Oh I've got kaowool for days. I bought enough materials to line my forge a few times over. I thought about doing just that, but wasn't sure how smart it was health-wise. 

Same thing, most likely. I've got some fire brick shards that are big enough to just lay across the top of the hole and block off most of the exhaust coming out of it. 

I think for now, I'm just gonna run it off one and throw a fire brick in there to reduce the amount of space it has to heat. I designed and built this before I really had any idea what I wanted to do, and I can't see myself needing a dual burner anytime soon. It's not an ideal solution, but it worked for me before, and if it becomes an issue, it's easy to undo. If that's a terrible idea though, let me know. God knows I'm not immune to those 

Huh, I meant to include the straight through shot. Looks like I accidentally uploaded the wrong one. Either way, I was playing around with it and got it to burn MUCH better. It still sputters occasionally, but it's doing the opposite of what it was before. Burns perfectly well 99% of the time, sputters for a split second, then goes back to burning just fine.

Overall the interior is 384 cubic inches. 

Alright, got a video of the best flame I can get out of it, and pictures of the burner if there's anything I need to change about that. I've tried .030 and .035 mig tips, and shortened one of each. Cutting 1/8" off either doesn't seem to do much, and 1/4" makes it worse. I've also played with the nozzles I made, the Zoeller nozzles I got, and a black iron coupler. The video is with the nozzles I made.

Yessir. I didn't get a chance to work on it today, but hopefully tomorrow I can knock it out and get back up and running. 

So I ended up building a T burner, and it's already working better. I'm still in the process of tuning it and figuring out a mounting solution, but I'm fairly pleased so far. I'll update once I get it mostly dialed in. 

I'm slowly becoming convinced the thing is possessed and just messing with me at this point. 

I can hear slight fluctuations, but the gauge doesn't move at all. I can't remember if I heard them when they were working well. What gets me is that the pressure it starts burning weird at was my basic forging pressure before. 

Nope, test failed. It seems like it's a temperature thing to me. I got the forge screaming hot and it seemed to do fine at higher pressures, but I turned it off and let it cool down/air out for about 10 minutes to just slightly glowing, turned the burner on to about 5psi, and same thing.

The one thing the original video I posted doesn't show is how quickly it changes over from burning clean to not. It just snaps over after running for a few minutes. 

Edit: I also picked my dad's brain on some of this. He seems to think my regulator is failing or that somehow, my batch of propane is contaminated. Neither of them make much sense to me, but I figured I'd throw them out there as possibilities. 

Frosty, you glorious man. I'm trying not to get too excited just yet, but it seems to be working. I'm giving it a pretty serious test right now and if it passes, I owe you quite a bit. 

Yeah, that fan in the back does oscillate, and I've tried having it point directly at the forge to see if that would clear anything away. I'll try laying modifying it to lay flat and see what that does. 

I didn't cut the top off, but I added some wings to the Frankenstein-like monster this is becoming. No change. 

So cut the flat lip off the top and extend the angled part out to the sides more? 

Same, man. At this point i'm leaning towards building some fancy new Frostys. 

Nah, I had just shut it down for the day and buttoned everything up to prevent making things even worse for myself lol. The picture was more to make sure my hood was enough to make any difference or if I need to go back to the drawing board. 

Well, we have a result: no difference. It did initially seem to take longer at first, but after modifying the hood slightly and letting the forge cool, it took about 5 minutes to go back to that teal flame. The fluttering is maybe slightly less aggressive, but it's minimal at best. The only other thing I can do is fill the receivers with kaowool to keep any exhaust from escaping there, but I don't know if enough is escaping there to really be of note. 

Yeah, when I initially posted it I forgot to give that file open permission to be shared, hence the warning. Both the flares that work better are installed, so I'll see what I can cobble together for a hood. I'll report back once I have some kind of result. 

I did, actually. The flared nozzles are the ones from Zoeller Forge. For some reason, my burners prefer my homemade ones, for at least a little bit. 

I'm not gonna lie, if I've stumped you, I feel a lot better about being unable to figure it out

At this point, a new burner was my only option left. I was looking at just buying a Z burner, but I'll take a look at your plans first. 

1/4" over about 2 1/4". A little over the 1:12 rule. 

The burner tubes are approx. 10" long.
