  1. The hinges I got at home depot were steel with a "brushed nickel" finish. Welded on with no prep. A farm supply or industrial supply place would probably have plain steel weld-on hinges. Yes, but by referring to your directions and pictures he can easily see the difference in the way the Dave Hammer burner that I have mounts as opposed to the way the t burner mounts. There's a big difference.
  2. Schedule 40, I think. Picked it up at a plumbing supply. You may not need it if you are building the T-burner. I'm not sure. Check with Frosty's design and go with that rather than mine of that's the case.
  3. Something I learned from my build that you can consider in acquiring your parts, and that others should take into consideration in giving advice, is that you can waste a lot of time trying to source exact parts from a single parts list and that you're going to have to track down a lot of small parts from different sources. As a hobbyist, I consider that my time is worthless in monetary terms, but it becomes a serious burden and annoyance when wasting time not finding the part I need, acquiring parts that end up not working and delaying the build by days or weeks because I don't have the free time to go all over town shopping, or when I had to have something else shipped. For that reason, I advise that the more you can get in kit form from the least amount of suppliers, the faster you will be beating hot metal. I suggest you get all your lining/refractory material from Wayne Coe. Along with supplying you with exactly the linings that go with his design that you are building, you also get e-mail technical support. I got the regulator kit from Hi-temp tools because Zoeller seemed to be AWOL. He responded to my first inquiry months after I had acquired my parts elsewhere. He may be back up and running now, but I could not get what I needed from him at the time. And, although your local propane supplier might be able to supply some parts, they are not nearly as knowledgeable about the proper configuration for a gas forge as opposed to a turkey fryer or a backyard barbecue. I have one extra regulator and about another $30 in unusable parts I got from them that I ended up not using. And that was with the burner in hand and telling them to start at the end of my burner and sell me everything all the way back to the tank.
  4. Yes I cut the tank and had the welding done before casting. I then lined it in 2 pieces. Be warned that cutting the tank kind of bumfuzzles the structure and you have to clamp everything back into place to line it up. Will post more later. Welder did the pipe, hinges, and a handle in about 40 minutes and charged me 60 bucks. Find the right shop and you might get it done for a case of beer.
  5. Day 1 was still mostly for tweaking the forge and getting familiar with it and learning how it behaved. After forging a slot punch and drift out of some mystery steel, which, of course, turned out to be 5% iron, 95% butter, I forged the bottle opener: Wire wheeled it and set it back in the forge, which was off but still pretty hot. I was only doing that to take a picture, but when I went to take it out I could see the colors running. Yanked it out with this nice blue temper to it. Dumb luck but noted for later. I didn't have the proper tools to forge a horse head. So I forged a horse head. After building up a modicum of confidence, it was time to get serious with a sucker rod knuckle. Holy crap, I need a power hammer. Day 2 was in the books. The horse head was supposed to be a bottle opener too, but the punch was a disaster. Never got to the drift. The slot punch was a fail, so I forged a round punch which I think will work better. Day 3. Forged a hand fuller and chisel out of a crowbar. No pictures as they are soaking in vinegar at the moment. The round punch does work better, but my technique must be lacking. I screwed up another bottle opener and then decided to go with the crane. I've seen them done and Alec Steele has a nice how-to on youtube, so I went for it. The proportions are all wrong and the drifted hole got distorted along with various other little failures, but it got made. Lessons were learned.
  6. I'm in no hurry to build the ribbon burner forge. I've got an old coal forge I need to restore first. Next gas forge will be a ribbon burner for sure, though. However long this one lasts may change the schedule, though. When I do, I'll do a build thread. I know nothing of thermocouples and such, but others here should be able to comment. Thanks. It is actually my first bottle opener. I've been smithing for a few years on a very occasional schedule at other people's forges. This forge is my first for smithing at home. The only technique new to me on the opener was the punch and drift. You'll see some epic fail in my latest attempt to punch and drift. Pictures to come... Hinges are on both sides. The entire top can separate from the bottom. Just knock the pins out of the hinges and Bob's yer uncle. This way you can raise the entire top by setting it on fire brick for large pieces. I reckon the only time I'll probably ever use that is if I uncoil a coil spring, or something like that. The hinges are standard door hinges from Home Depot with screw holes. I suppose they could be screwed on, no problem. I needed a welder to weld the burner pipe on, so he did the welding on the hinges as well. He did plug welds in the existing screw holes. Works great.
  7. I'm not discouraged with the outcome. I've done very few tweaks and it's running like a scalded dog now. I haven't yet attempted welding temps for this one but for general forging I think I have it a lot better dialed in now and it didn't really take as much adjustment as I expected. Once it's up and running the heat evens out a lot more than before, plus, shielding it from wind made a much larger difference than I expected. I didn't go in with high expectations for welding, but we'll see. I think I can get there. I have a coal forge I'm restoring for the next one and then doing a ribbon burner. I think I'll keep this one as a back-up, or secondary unit. Or I may sell it after the ribbon burner forge is done. Regardless, I'm way ahead of where I was the first day I fired it up and a lot of it is thanks to info you guys posted in this thread. It mostly just needed some tweaking. The first thing has been forged from it (actually the first 3 things, because I forged a punch and drift to be able to forge the bottle opener):
  8. I'm certain that one of those solutions is in my immediate future.
  9. Thanks, Thomas. It didn't "freeze up" with frost on it like I have seen discussed here. It was about 50 degrees yesterday and the tank didn't feel much colder than that. We'll see, when I fire it up next time.
  10. I'm at Earnhardt's level... at something. I'll let you know when I figure out what it is. I think I did pretty good. It seems to be heating up metal, and I learned some stuff. So here's a simple enough question from a noob: In general, does performance suffer as the fuel tank empties? It feels like it's at about half-full. Maybe a bit less. Something caused the sputtering and ignition in the mixing chamber about an hour in yesterday. Need to figure that out. Today is a cold day with plumbers ripping up both bathrooms, so all I get to do today is sit and speculate.
  11. I know it sounds like a lot of changes, but it really wasn't. All the initial tweaks took about 10 minutes. 5 minutes after that I was beating hot metal. That's what you said in your first response, no? "A few tweaks"? I haven't and don't plan to rebuild this one. I've tweaked it. I might need to tweak it a little more, I'm mostly happy with it save for getting the scale issue figured out. The openings are a size I desire and can be closed down easily with $2 worth of fire brick. I did it today. I'm not building forges to "experiment". I'm building forges to forge stuff. For better or worse, what it is, is what it will be, as will the next. I get your point about not using different designs, but search around and show me any two homebrew forges that are identical. I see a lot of really fine work from people using the sketchiest of equipment. They're one step ahead of me: They've done really fine work. And remember... Every NASCAR race Dale Earnhardt ever won in a Chevrolet was riding a Ford 9" rear end. Cheers
  12. Thanks, Wayne. The back door was blocked yesterday and was partially open today, so that makes sense. I'll close it back up tomorrow and see.
  13. Did some tweaks today, repositioning the burner tube to skew slightly, filed out a bit more of the opening for the flare (it was a little bit narrower than I think it should be). Added fire brick to serve as doors, cut about a 1/4" thick piece from fire brick to serve as a bit of a riser for stock. It performed well in the 7-10 psi range. Heat is spreading out more now. Much more dragon breath than yesterday. The downside is scale through the roof. Lots of adjustments on the choke and never did get it dialed in. About an hour in it started sputtering and whistling, so I shut it down. The tank wasn't frozen up and is still about half full. Could the flare be getting hot enough to ignite the mixture in the burner tube?
  14. Thank you, Wayne. I debated with myself whether to orient the burner as you do on the forge pictured on your site. Most of this build was from your instructions, however I also took design cues from David Hammer's Super C design, and perhaps wrongly, I chose to mount it like he does for that design. If you look at his Super C, the burner orientation is more or less identical to mine. I understand there could be differences I'm not aware of, though. I chose to do it this way based on that, and because of the simplicity of the fabrication. That was my thought process, anyway. Won't be an issue with the next build which will be a ribbon burner. As for the gap, I went back over it twice while the mortar was still soft, but apparently didn't do such a good job of it. The items I show working are things I had handy to heat and beat in a test firing. I'll be using fire brick to close up the opening when it goes to work for real. I appreciate everybody's input.
