  1. Great advice, Thomas. Do you have a thread with pictures of your rig? Kraitok, my air tank was approx 11" in diameter and 19" not including the doors. I have approx 2" or so of wool/refractory inside which gives me something in the neighborhood of 7"x19" fire box. If i build another one, I am going to either do one that has more girth and less lemght or a square one. Said somewhere in this thread, 350 or so cu.in. is the sweet spot between using a single burner and not wasting excess fuel.
  2. Alright then, best of luck I look forward to seeing how yours turns out. I would just advise to do what youre doing. This forum is a wealth of knowledge. Glean all you can. Dont be bashful about asking for help. On a side note, I got into a fight with an angle grinder today and after an 8cm gash and 19 stitches to the left forearm.(not forge related) I guess I will have time to tune burners and reduce the internal volume of my firebox. Above all else, please be careful. We are dealing with some dangerous stuff! For what its worth, I had on double eye protection, ear plugs kevlar gloves long pants and composite toes. Even with extreme precaution, things can go side ways.
  3. EDL, thats hilarious! Yeah i was aware of the difference, but it seemed that Google wasnt so much. Anyhow, I have recieved a GOB (eastern North Carolina term) of great tips and advice. I like to feel like I have really stretched the more experienced member's knowledge more than their patience! Dobt wait til then to begin accumulating materials to build your rig! Good luck and if you need any help, IFI is the right place!
  4. Sounds good, Tink. I intend to do the bypass circuit for that reason as well. I have some pipe fitting to do to arange my two venturi burners first.
  5. Tim, that looks great! Is that with one burner? If so, what is the size? 3/4"? Also, about how much run time does it take to get your forge that hot? Nevermind about the size and number of burners, I zoomed in on your first picture and I think youre using a ribbon burner. Correct? Anyhow, how long does it take to get get to temp with it?
  6. I was actually thinking of adding a semi-circle "wedge" to make sort of a flat "floor" to yhe insode of it... But I have some insulating firebrick that i am going to try first.
  7. Ok cool i have an infinite supply of regular firebrick and about 4 insulating firebricks that are about 4"×8"×15". I should be able to work out some sort of plan with those.
  8. Buzzkill, I actually wondered if I could fill in part of it and accomplish the same purpose... I have all the firebrick I want, but i was concerned about them being a heat-sync and still robbing heat from the firebox itself.
  9. Buzzkill thats some good advice. Being that I am a big novice, I just did things arbitrarily. Having zero experience to go on, I figured a firebox diameter of at least 6" would accomodate what I want to do. I just took the air compressor tank and used it at the length it was manufactured. Mr. Powers, I totally agree with the dump truck analogy. I know a novice painter need not focus much beyond primary colors, but I wanted to be able to grow into things somewhat before having to build another one. I was thinking along those lines when my good friend offered me an old compressor tabk to use early on. It is 20 gallons! Twice as big as mine! I would be even more on a fools erand! To answer both of you guys, I dont have an exact "thing" I am setting out to forge. I have been facinated by metal working, specifically blacksmithing for as long as I can remember. So my intentions were to start out small and heat some metal of varying compositions merely to see how they respond to the heat. Then once I have expored that, I want to try my hand at forging functional things (in no particular order) increasing in diffuculty... Tongs, bottle openers, steak turners, knives. I definitely dont think I want to undertake swords. So I wont be needing that dump truck! As for the size, I am exploring options on reducing the size. I think I could farily easily, cut the shell with a cutting wheel, then use a masonary bit to trim the refractory. I will have to move my hinges and latches, but hey, I'm becoming used to modification!
  10. Hey Buzzkill, I have been brewing on your last reply. I did the math and with a radius of 3" and a total lenght of 19", if my figures are correct, I am looking at like 537 or so cu.in. I didnt figure 6" round opening was too large, but does the 19" deep firebox put me over size for an efficient rig? And what is the relationship between regulator setting/number of burners/fuel consumption/internal heat roduction? I still have the sleeve for a second burner. I can appreciate how far I've come, however there is plenty for me to learn as I tune the old girl.
  11. Ok Swedefiddle, youre right about the time I had it going. Less than 15-20minutes. As for the 'babys-breath' can you tell me more about this? Honestly, this is the first time I have heard of it. Buzzkill, yes its a 3/4" nipple that flares out with a 3/4" to 1" bell reducer. I want to grind out the threads on the 1" side. I think that will refine the flame shape even more. I haven't calculated the volume of the fire box, but I cant see it being 350 or more cu. in. Also, yes they are firebricks in the opening. I was trying to trap as much heat in as possible. And, boy, do the get HOT! A lot of what i am trying to figure out is how long would it take to get the firebox up to temp. And the fuel balance between two burners. Mikey, I was really happy withthe flame. Like I said, I generally followed the instructions on the video that i posted when I started this thread. I have read a lot of burner threads that were not as successful as mine turned out.
  12. Just a quick update video. There is a lawnmower blade in one end and a piece of half inch no name solid stock in the other. Since I am so unfamiliar as to how the forge responds to heat and how the metal reacts, I just stuck a couple pieces of junk metal in to see how they take heat. I ran the forge for about 5-10 minutes at around 20-30lb pressure on the regulator. Both pieces of metal got cherry farily easily and fairly quick. I only have one burner in. The only time I tried two didnt turn out as smoothly as with one. Im going to have to study on it some more. Probably have to put throttle valves in and gag one so it doesnt steal all the fuel from the second burner. Take aways: 1. I still have a ton to learn. 2. The neighbors are going to hate all the racket associated with forging. 3. It was enormous fun! How does the flame shape look to yall? Is there any thing else I need to consider? I am going to look up some pf that reflective paint to coat the inside with also. 20191020_165311.mp4
  13. Heard the rubber mallet one also! My roomate in college was known for saying "...and what he doesn't tear up, he looks on!" Refering to me! Anyhow. Fun times! Much appreciation to your grandfather! I have tons of respect for our great military! I am a civil servant on a marine base in eastern NC. Those Devil Dogs are tough!
  14. PNUT, i read somewhere that people had put theirs in a bag or container. Honestly, i forgot all about that step. The guy I got it from said in the industry where it is used, the best way to cure this type is to put heat to it. Low-fire or a lamp. Im glad it didnt crack. I will see how it takes heat when i get the lids fitted back up. Frosty, holy cow! 350lb hammer! Wow! I also have a piece of steel that looks like a big hockey puck. It is about 4" diameter and about 4" tall. Theyre used on rail cars to roll with the weight of liquid in tank cars. They dampen the "slosh" when the train stopps. It is good and flat, i just wish it were bigger! I also have 2 pieces of plate steel that are about 2.5-3" thick, I believe. Youre right though, whatever you use to bang out stuff with ends up being the anvil. My dad always said I could tear up an anvil... Hopefully i wont prove him right.
