  1. I would however all of them shipping distance only. I am getting to know a couple of them over the phone though.
  2. I will definitely update once I try out this Kalakast. Yes there are some crazy refractories out there, HWI, URC, Morgan thermal, allied minerals, vesuvius and that's just the name not the products. Most of these companies make their own stuff like bubbly alumina mizzou etc. The problem is finding a supplier that happens to either stock it like the basic kalakast, unicast, loucast, house brand or get lucky and happen to call when they have a partial pallat of specialty refractory. These guys have it made up in pallets and it only has about a 6mth commercial life so the stuff gets custom
  3. Paul I'm interested in how this works out for you if you buy it. I bought a box of wool from Inproheat and got talked out of the unicast for the same reason, I should have grabbed it though it looks like it'd work. I'm going to try this Kalakast product, I'm told it's basically mizzou but more alkali resistant, maybe tough against flux....... Rep says they use it in the crematorium incinerators a lot. Here's the breakdown of kalakast and mizzou, they're also similar to the unicast. You can get kalakast for around $70 cad a bag from a HWI outlet/warehouse.
  4. I guess I could see that flange being a bit sloppy...... Twas just an image that popped in my head. Anyway yes the locking nut seems the best idea. I found a pipe chart so I'm heading to the plumbing store tomorrow to gather a few more bits. Thanks guys for your patience I'll update if I have success
  5. I was thinking of being able to lock the burner in the forge so doesn't rotate. Now say the threaded 1/8" fuel jet accelerator stays stationary, like it can't turn. Now the piece I am envisioning would be like a nut that can turn on a flange that would welded to the outside of the T. This way you can adjust the nut and move the accelerator in and out without removing the burner from the forge. Obviously this is frivolous, it's just something rolling around in my head. Please if that is still confusing just disregard this. I am having a hard time putting it into words. Hah
  6. Hey Frosty, I'm not sure how I confused things I was talking about two different things...... Yes using a jam nut will lock the jet in position whether it's in a T like the last pic or through a threaded bushing in another design. I then was asking about the step nozzle and which sizes of pipe were used So I was asking about the carb then the exaust. When I was talking further about adjusting, I can't really describe what I was/am thinking about and in the end it's not necesary.
  7. Ok thanks that explains it I think. I kept using varying lengths and combos of the 1" black pipe and the 1 1/4" black pipe and kept fixating on needing to use standard pipe nipples and not other combinations. Now I'm going to see if I can get some schd 80 1 1/4" it, in theory it should only take a bit if grinding to get a tight fit.
  8. Thanks Mike, I'm going to go back and try a couple more going slower When you make a "step nozzle" for a 3/4" burner do you use sch 40 or sch 80 for the 1 1/4" nozzle portion? I'm finding the 1 1/4" sch 40 nipples are almost 1 1/2" ID so real sloppy over the 1" spacer and I'm getting too much pressure drop.
  9. Thanks, in the forge tests will be coming in a couple days This is hard to describe but I'm wondering if there is a type of adjustable nut thingy that could be fixed to the T but have a nut that turns freely so that the burner and the jet can stay stationary but turning the nut would just adjust the jet in and out. I think I've seen something like that before but can't think of where or what it would be called......? Any ideas, does that make sense? I guess kinda like the screw in a crescent wrench but a female version...
  10. I had a little breakthrough yesterday when I was tinkering. Now this may be documented already but I found that you can cut threads on the outside of the 1/8" sch 80 nipple using a 7/16" 20nf I think it was. Also you can drill and tap the 1/8" fittings with the 7/16 20nf this way you don't need set screws you can screw in and out to tune as long as you got everything straight. And in some designs like a Mikey, Oliver, straight straight tube burner you may be able to stream line a bit with let's say the 3/4" steel, straight sided coupler/thread protector then a 3/4"-1/8" bushing tapped for
  11. AFB thanks ya they're for holding RR spikes by the head. So far they seem to work fairly well.
  12. Oh boy I missed a bunch while I was away. 671Jungle, that's a beautiful flame nice stable shape. Hey Mike I already had two burner Tubes made up so I would be able to try different lengths after the air slots. For some reason I can't get a decent flame burning outside the forge, I'm trying to use a step nozzle and have put it together in several configurations but I either run rich with the orange flame or I blow the flame out. I cleaned up the air slots, trimmed the mixing tube to 8" after the air slots, 0.023 contact tip. Inside the forge I can get these flames. I get no dragons
  13. Hey Mickey "very hot" is a good start, I already have a .030 tip turned down so it's a real easy change over. I have not read your book only picked up dimensions here and there in this thread and others so I've kinda pieced those bits together. The mixing tube portion (from the tip of the burner to the beginning of the openings) is 7 1/2" if that's too short I have another tube all ready made up that is about 8 3/8" so I have a little bit of option on length. Could you refresh me on how you determine a "very hot" flame? Is it because of the compact conical shape vs a looser flame th
  14. When the burner is in the forge the current pieces I am using as a nozzle only act as spacers, they butt up to the flare in the liner. Outside the forge I just slid these spacers out into a multi step type nozzle just to see how it would act ( I do have other pieces to make a step nozzle as Mickey describes which will be used in future testing ). Your description of the flame makes sense and adds to my ability to visualize what I am looking for. I guess the first thing I do tonight is going to be taking this apart and give it a clean again to make sure I have zero residue left to rule tha
  15. The last 3 pics are all without changing anything with the burner but the amount of orange will constantly change. In the forge the nozzle is cast into my liner however outside the forge I have a step nozzle on there. The nozzle is a 1" nipple with a 1/2" overhang then a 1 1/4" overhanging the 1" by about 7/8". The orifice seems to have the same outcome when I set it between 1/2" from the bottom of the air slots up to about 1 1/2". I have another jet set up with a .030 tip that I will try out tonight but in the meantime if you have any thoughts I am all ears. Frosty thank you. I w
