    The cast nozzles were made using 3D printed forms that mimic the 1:12 taper spec that seem to be the standard. The taper starts approximately 1/2” into the lining measured from the shell. Once up to temperature the forge is only running around 8-10 psi. I’ve tried cranking up the pressure some but it doesn’t do much besides speed up the sputtering sound.

    Cleaned out the tips this morning and the forge worked fine again. Tested the temperature with a small piece of copper, which melted readily when the forge was up to temperature. Copper melts around 1980-1990 F or so, so I’d guess I’m north of 2000F somewhat. Pleased with that. I was then working on a set of tongs and that front burner started sputtering rapidly again. I’ll clean the tip out again, maybe some tape from a fitting is coming through but I can’t help but wonder if it’s due to the heat or something. I also noticed that the top door tracks were glowing a dull red on either side when I shut the forge off. Maybe unrelated but I figured I’d share anyway. Overall the build has improved a lot, thanks to everyone helping me out on here. Thanks a ton to Mikey, Frosty, and Irondragon for all of the help and tips during the process. There’s a great community here.

    And by "heat issue" I mean for the burner components, sorry.

    After trimming more tips for these burners they're pretty close to even with each other, but the front burner is still running hotter. A new tip on the back burner took care of the excessive "richness" that it was showing. The flames themselves also look fairly similar. I decided to run the forge up to temperature and stick some steel in there to see how it performs, and, given that I was under more optimal lighting, I might dare to say that it's looking rather yellow to me, although I kind of want to order a thermocouple or something to measure the temperature so I know for sure. The dragon's breath is mostly blue with some orange in there, but it would change to green every now and again, probably due to some copper that wound up in the chamber from fiddling with the copper tubing and sanding down mig tips all day. The forge worked wonderfully for an hour or so and then both burners began suffering at almost the same time. I heard the change first and then small pops/poofs at the tip itself would happen occasionally and the burners began sputtering rapidly, even with the doors wide open. I shut it down right after. During the cool down I flipped them back on and they would only sputter the same way. I'll check/clean them out for debris tomorrow, but I'm curious if this could be a heat issue as well? Let me know what you guys think, thanks!

    Bending the tip didn't seem to do much, and I went ahead and replaced the tip on the back burner, as filing it down some more didn't do much. I was too aggressive with the tip file. I went ahead and made another pair of T's, making sure that they line up with the mixing tube. I'll swap those out and see how it goes.

    I guess I'll find some more T fittings and try and do a better job at centering up that hole for the MIG tip just right. And by "lifting off" you mean how the flame tends to wander from the flare opening, which looks to be a problem with both burners, correct?

    I run tip cleaners through them pretty thoroughly after I sand each little bit down, I saw what you meant and ran the cleaner through again. Shaped up a bit better.

    I've since placed the burners back in the forge. I started tuning the front one and I think it's pretty close, definitely improved. I've been working on the back burner and have trimmed off quite a bit of the tip, but it still appear to be weaker than the front one and tinged green, but it's shape improves whenever both burners are running. I'll post pictures below. YouTube link here. Front Burner Back one, not as clean a cone. Likes to smoosh into the floor initially, cleans up when both are running. Both running together, front one is clearly hotter. Frosty, my mig tips are 0.023". In terms of determining alignment I've basically just eyeballed it. I had help making these with a bridgeport and they look pretty good. I left the front burner in the forge because it seemed to be running very well, but the rear one had issues so I took it out and took some pictures of the tube.

    Got it. I'll stick the burner back in the forge and start testing. Thank you for your help Mikey, I appreciate it.

    I should sand off a little bit and test the flames inside the forge correct?

    Mikey, All of the parts are the right size, the T is 3/4" run and 1/2" branch. Everything looks bang on centered and parallel to the mixing tube. I've never trimmed back the mig tips before because the flames didn't look rich inside the forge. Along with that, my burner flares were cast into the refractory so I don't have a physical flare to attached to the burner and it won't sustain a flame outside of the forge. Should I just go pick up a small reducer fitting for this purpose?

    Where would you suggest looking? I’ve taken them apart and cleaned out the mig tips several times. Everything looks pretty well centered to me. The flames aren’t running rich are they? I thought they were decent.

    I haven't noticed a huge difference either way I space the doors from the openings, certainly not any major temperature improvements. I've fiddled more and more with the burner tube alignments in the casted flares and I think the flames look pretty decent (pictures at the end). I'm trying to figure out what else can be done. Some of my current thoughts: 1. The forge chamber is somehow too small and is causing pressure issues that are limiting the capabilities of the burners/flames. Not really sure this can be fixed if it is the case. 2. When I applied the metrikote, it was probably a tad too watery. I made sure to keep the material in suspension when I was brushing on it though, all of the powder definitely got brushed on. Could this have caused anything? I would think this would just harm efficiency/time to heat rather than reduce the attainable operating temperature, but correct me if I'm wrong. 3. When adjusting the burner tube alignments, several small chunks of the KastOLite that were loose in the casted burner flare fell through. This actually seemed to improve the flames and also produced a notable increase in the volume of the roaring that the burners produce. Figured this was worth mentioning, but not likely to be the problem. Not quite sure what else to consider, I can run the burners at over 15 psi and I just get into the bright orange range, no sign of yellow Any advice is welcome, thanks!

    What did you do in the shop today?

    I like that idea quite a bit. I don't see my self working anything long enough to need a rest on both sides for a while, but the versatility of that option sounds great.

    Learned how to weld the other day, not pretty but it works well enough for sticking metal together. Welded some scrap tubing I had to the sides of the forge and bent an adjustable work rest out of some round stock to fit, turned out better than I thought. Huge quality of life improvement there, still working on optimizing burning performance though (picture is during cool down).
