  1. Sendit, I'm not the best to analyze fames but that one looks really rich. Your gonna burn through a lot of propane with 3 of them. Looks like you made one of Larry's sidearm burners. Since you are making these for a large crawfish boiler I am also assuming you are in Louisiana. I live in central Louisiana and had some results with the sidearm burner. No matter what I tried it would always run rich. I said it must be something with the air volume or whatever around here lol. Anyway I would be more than happy to give you a hand if you are in the general area.
  2. No doubt and I'm helping a buddy from work build one plus another in Ohio. All b/s aside, if you guys come across anyone from the central Louisiana area that needs in person help, send them my way. I'll still be lurking around here to chime in with any help I can offer.
  3. Does that mean I've graduated from the forge building section of IFI and I can use the rest of the forum?! Thanks again for the help.
  4. Fires forge up and got it hot. Put a shiny piece of 1/4 x 1 bar in. Took about 3.5 mins for it to get just at yellow hot. Tried brushing it but couldn't get any scale. Put it back in and got to same temp then tapped a few times with hammer. Got some scale but not much. Took these two pics after the forge was running for about 15mins. I had the door covered while heating up.
  5. The picture really doesn't do justice, they look almost identical when running. If anything the back one might flare a little rich every now and then. I'll try the scale test tomorrow when I get done with the "honey do's". I have some K26 insulating fire bricks for forge doors. Thanks again guys.
  6. Maybe Mikey but I'm afraid to touch them lol. Don't know why but it's finicky. Any change and they want to get rich again. No worries Buzz I was going to share what I had to do. No matter what I did with 035 tips it would run rich. Ended up having to use a 030 tip trimmed down halfway on the closest burner. Tried same thing on the back burner and it would run rich. The back one took a full length 025 tip to get right. I don't understand why, it's gotta be something about the volume of air or whatever around here. Thought maybe the burners might be starving each other but I get the same results when running them individually.
  7. No worries Frosty I can definitely understand your frustration at times. Yes I did review your T burner guide and found the correct brass 1/8 npt x 1/4 flare fittings. Local shops had some thick walled ones you could drill/tap and some thin wall ones that could not be used. I recommend anyone going shopping for these to bring a mig tip with them. I used Tweco style tips and a 7/32 drill bit combined with 1/4-28 tap worked fine. For drilling into the T for the 1/8 npt tap, an 11/32 drill bit works really well. My fuel cutoffs are on the tank side of the copper tubes not on top the T's. Anyway I left work early and spent the afternoon working on these burners. I am happy to say I think I got them running correct now and they are burning hot! Flame is a beautiful dark blue and very little dragons breath. See pic below and let me know what you think. I'll let you know what I had to do other than securing the fittings and copper tubes.
  8. Buzz, thanks for the info. Didn't get as much shop time after work today. The warden aka "wife" pulled me away then had to get kid from jujitsu. I did manage to get the valves/fittings secure so they and copper line shouldn't be pulling down anymore. Also drilled and tapped a new 1 x 3/4 T incase my old one is off any. Took extra special care make sure I was dead center as possible with drill press, used the floor flange method. Should be able to get the 035 trimmed and test it out tomorrow. I may also try to solder the tip to fitting to eliminate that possible variable. Thanks again.
  9. Frosty I've scanned every post in this thread and don't see where you talked about the tubing weight and pulling down. I definitely agree with you and will make those adjustments. The tubing was hooked up as so for temporary testing. I'm not ignoring any suggestions and welcome any constructive input. I tried the 1 1/4 Tee for testing purposes and out of curiosity/suggestion from Mikey. I got data from the test either way. I wanted to try the sidearm burner because it seemed easier to tune but that doesn't seem to be the case for my setup. Like I said in an earlier post I've put it to the side for now and only working on a Frosty T burner. I will secure the fittings and copper so it shouldn't be pulling down tomorrow and only work with the 1 x 3/4 T setup. What size mig tip do you suggest to start with for my conditions? Remember I'm not far above sea level, the air here is heavy and often humid. Thanks again for all you guys contributions to this community.
  10. Thanks for the replies guys. Buzz/Frosty I complete agree that it shouldn't/couldn't be running rich and I really wish it wasn't lol. I just want to get back to forging . Anyway the best I can tell the tip is centered. I made a 1 1/4 x 3/4 burner this evening and ran some test with different tips. Also ran more test with a 1 x 3/4 T and different tips. Hopefully the pics below will be helpful to you guys. Flames definitely look better, a lot more blue and minimal dragons breath. Also the unused burner port was plugged with scrap kaowool. I know I'm gonna get fussed at for using galvanized Tee's but that's all I could find locally. Nearest black iron supply is 45 mins away and I couldn't get there today. Rest of the fittings are black iron and brass. Thanks again guys.
  11. For the "Frosty" T burners. I know it's unusual but don't know how else to get more air in the mix. Bigger mig tip couldn't be the answer, could it? Ran rich with 023 at pretty much all lengths. I already have 1 1/4 x 3/4 for the zoeller burners. Putting these to the side for now. Getting better results from the T burners now.
  12. $40 - $50 most places. Not crazy but a bit much for 1 fitting. I tried the 023 tips and was still rich so I don't know. Started playing around with frosty T burners again out of frustration with the sidearm. I had to cut the 023 mig tip down all the way to about 1/8 left to get the flame more blueish. Stable flame I could turn up to 20 psi and down to 2 psi without it blowing out. I know I'm still rich with still burner setup as well. I can blow a little air into the T while running and get a great dark blue flame. It has to be this Louisiana air. I'm only at 56ft above sea level so it's heavy and sometimes very humid. Maybe a 1 1/4 x 3/4 Tee for more air? Thanks for your responses Mikey, I appreciate the help.
  13. Picked up some .023 mig tips today, will try those out. If I end up being to lean I'll just have to add some chokes I guess. The "special" T fitting Zoeller uses on the newer style is a WYE Tee. They are a little pricey and not available locally. I'll post an update tomorrow.
  14. Yes I baked it after I built the forge a few weeks ago. Also ran a pair of T burners in the forge for a while before making these sidearm burners. From research I've done these sidearm burners are supposed to be easier to tune, that's why I switched. No offense to Frosty
  15. So i built a pair of 3/4 sidearm burners for my propane tank forge. I calculate the volume to be around 460 cu in. I know two 3/4 is a bit over kill but two 1/2 burners was going to be under sized so I plan to turn down the pressure or turn down one burner once I get the forge hot. Anyway, I ran the forge a bit this weekend and the "dragons breath" seemed a little overwhelming. I pulled the burners out today and tuned them in a vice, then re-install and adjusted a little. The dragons breath still seems a bit much once the forge gets going. I'm attaching some pics of the forge running at 5 psi and 8 psi after just lighting it. Also a pic of both pressures when the forge is really going and what I think is a bit much dragons breath. Best I can tell it seems like the burners might be running a bit rich. I have a .025 mig tip installed in each. The forge is lined with two layers of 1" kaowool, kast-o-lite 30 over the kaowool, and layer of Plistix for efficiency. I shined up a piece of flat bar and put in forge to see how much it would scale. Once it got orange hot I pulled it and brushed it but no scale came off. Put it back in and pulled at orange hot again. Tapped a few times with hammer and got a little bit of scale to come off. This leads me to be believe that it might be too rich but I'm definitely not an expert. Any help you guys can offer would be much appreciated, thanks.
