Irondragon Forge ClayWorks Posted December 4, 2021 Share Posted December 4, 2021 I think that is your problem, too large of an orifice. Without measuring it, I would say it looks like about a 1/16 (.0625) or 3/64 (.0469) orifice. You might want to ask your friend what size drill he used to drill them out with to confirm that.

Aframe Posted December 4, 2021 Author Share Posted December 4, 2021 If I were to solder and drill again. What size would you recommend? Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 4, 2021 Share Posted December 4, 2021 I see a number of less than optimal features. Besides drilling the jet too large, the mixing tube is way too long and the flame holding flare is . . . Nevermind. I'd build new burners. T burners are easy and require the minimum shop tools and skills. The plans are pinned in the burner section and I'm around to help you tune them if you have trouble. If you want to try to get those to work, start with a 0.030" drill bit so you can work your way UP. It's easy to make a hole larger, making them smaller not so much. With that long a mixing tube 0.030" might be as good as it gets, I'd start over but I'm good at making propane burners, lots of practice. I have the drill bits, taps, mig tips, fittings, etc. in cigar boxes depending on burner size. The ones you have were almost undoubtedly re-drilled with a letter gauge drill bit without knowing WHICH gauge scale Fucina used in the manufacture. Even in SAE there are more than one letter gauge scales, It's why I MUCH prefer decimal fraction to gauge when measuring virtually anything. You can find decimal fraction wire feeler gauges at any decent tool store and most good auto supplies. Little drill bits are harder to find and more expensive. Personally I prefer to know what size hole to drill BEFORE buying the drill bit. I get undersized bits in the size I need, get a couple few, they break stupid easy. There are lots of jets in a modern auto, more than when engines were carbureted. Whatever you decide we'll do what we can to help get them working properly Frosty The Lucky.

Aframe Posted December 5, 2021 Author Share Posted December 5, 2021 Thank you Frosty. I’ll definitely check out the how to section. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted December 5, 2021 Share Posted December 5, 2021 I'm afraid John doesn't know much about propane forges. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted December 6, 2021 Share Posted December 6, 2021 Or care, apparently! Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 18, 2021 Share Posted December 18, 2021 Hopefully he got it working properly and didn't just give up the craft. Are you still around John? Do you have more questions? Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Aframe Posted December 18, 2021 Author Share Posted December 18, 2021 So I drilled the orifices out and put in a plug. I adjusted the depth the price was sitting in the mixer tube and it seems to be working much better. I think it might need some fine tuning but it’s so much better. Thank you for all your help everyone! I also picked up parts to make a manifold for a separate set of burners in case these get weird again.

When I said John doesn't know much about propane forges, it was referring to John from Fucina forges and his answer to Aframe. It looks like the forge is running better to me.

Mikey98118 Posted December 18, 2021 Share Posted December 18, 2021 I an assuming that the color in that photo is off a little bit, and that orange tertiary flame is actually red? In that case, be prepared for a lot of scale. Quote Link to comment Share on other sites More sharing options...
Aframe Posted December 19, 2021 Author Share Posted December 19, 2021 The flame actually looks pretty orange to me. I’ll actually get something forged one night this week and see if I get a lot of scale. Thanks for the heads up. I do think it can be tuned a bit better but it’s miles from where I started with it Frosty I figured you meant John at Fucina but thanks for the clarification Quote Link to comment Share on other sites More sharing options...

I'll just sit here and slap my forehead for a while. <sigh> The latest pic looks much better. It still looks pretty rich but getting close. Let us know how it works for you. Once you get the burners tuned we'll help you fix that . . . less than optimal forge. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted December 19, 2021 Share Posted December 19, 2021 So, actually orange? I'venot a clue. BTW, have you tried turning off one burner at a time, to see how the flames on the other two change? That could provide a valuable clue. But for now, I think you still need smaller gas orifices in those burners. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 19, 2021 Share Posted December 19, 2021 BTW I think that manifold will work better if you have the inlet between the burners and not inline with them. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted December 19, 2021 Share Posted December 19, 2021 I like those tiny fittings; where to find them; assuming that we are looking at 1/8" pipe? Quote Link to comment Share on other sites More sharing options...
