  1. One burner first forge

    I found this site a couple weeks ago while searching metal art images. Having acquired a few related tools already, I decided to try making a forge and see where this takes me. The body is 12" casing, the ends from an old water heater, various pieces from the scrap barrel. The insulation material is in and I still need to rigidize and coat it. The plan is to place one K-26 firebrick (possibly coated?) as a replaceable interior base. The brick will end up at the height of the end cut outs. The burner is slotted 3/4" iron pipe with .030 mig tip for orifice. I haven't tried a choke on it as of yet. It lights up and roars pretty good in the free air but testing in the forge is yet to happen. The sleeve around the burner was intended as a bushing to stabilize the burner in the holder. Once the inside gets coated the volume should end up just under 350 cu. inches minus the volume of a 1.25 x 4.5 x 9" brick. I need to get colloidal silica and Kast O Lite coming to complete this. A buddy says he has some castable refractory but I don't want to risk getting something that isn't right. Comments a criticism would be greatly appreciated. Burner size? end openings? ??
  2. Forge wall thickness

    Hello all. I have been browsing and trying to find just a general answer for the question, “How thick should the ceramic blanket be?” i have been looking around I’ve seen for sale anything from 1/2” to 2” blankets. I am repurposing an old #40 propane tank into a forge. I will be cutting a small rear access and a door up front with a shelf to rest fire bricks. What thickness should I be using and would this be a two burner project in your opinion? thank you for your time!!
  3. First Gas Forge (UFO build)

    Hello all, Wanted to share my first build with you guys so I can hopefully get it done in a good way the first time. I am still working on getting supplies together. I don't have a bunch of fab equipment, so I am trying to re-purpose this old stainless sink. I am looking to create a really basic forge so I can get to heating steel relatively quickly, both in the sense of a easy build, but also a build that is well insulated. One thing I am still thinking out is the angle of the burner. I know a 10/15 degree offset is recommended. I am going to try the Zoeller sidearm burner, which I know is rated for ~350cu/in, so I will work on get the insulation sized correctly. Any tips or critiques, please send them. Thanks, Mic
  4. I came across a kiln that a neighbour was throwing out, and decided to make a forge. Finally! What I always needed! So I have 51 soft bricks(4.5x2.5x9) to work with. I can pick up some hard bricks without hurting the bank account too badly. 5.99 each at home hardware. About half of my free, soft bricks are cracked, and the other half aren't. The is photo is the first idea I had. Feel free to add your two cents. I'll be seating the final design in a metal frame, but am playing lego on this piece of ply for convenience sake. I wondered about mixing a thinnest style mix to coat the interior floor of the forge to protect the soft bricks. I'll also be adding a propane head source, but thought I'd start with the box. The chamber itself is 7"wide, 4.5" tall, and I think I could go three bricks deep if I wanted, I think 27". I've also got a million red bricks I could use. Which I considered as the base layer of the forge, which would be cost effective(ie. Cheap.
  5. Possible Burner Idea?

    I found this youtube video on making a simple burner for a gas forge. I have made a burner to melt aluminum in a foundry before. With most burners (and the one I made) I find that they cost a lot to make or require a lot of up-keep. This one seems almost too simple. What do y'all think? I'm not looking for it to last my whole life but to just get started in gas forges. https://www.youtube.com/watch?time_continue=5&v=67rxU02fv6o (P.S. I would make quite a few modifications like an air flow regulator and such.) Your boi, Jacob
  6. Gas Forge Confusion

    I am looking to upgrade from my coke forge to a gas forge, and I don't quite know what to do. I can buy one of those fancy centaur forge ones for half a grand, buy one of those ebay ones for 150$, or make my own. It would be hard to get enough money to afford the 500$ ones, and I don't have access to a welding machine currently. What do I do? Thanks, Jacob
  7. Made a Forge, Doesn't Work

    Hello all, I know I'm probably like the hundredth post about building my first forge, but here I am following suit. Firstly, it was my first time using a mig welder and didn't know that you use it as any other welder, whoops Secondly, I haven't done the most research because I'm on a time crunch for Christmas, but i have done some thanks a lot to your site and Youtube. Thirdly, I'm very close to being broke so hopefully any major adjustments aren't needed. Fourthly, I'm grateful for any and all responses and advice. Alright so, My forge doesn't get hot enough, like not even to where the metal gets a little glowing, just turns them black and kinda blue after 30 minutes. It will get kind of red hot if i hold a piece of steel outside the opening. If i close the opening with that loose fire brick it will snuff the burner out, but i will still get flames that will shoot out of the air holes in the burner (not safe). It's a propane burner from Harbor Freight, I don't have a regulator on it, and i never adjusted any tip or anything like that. They are hard fire bricks from Menards 9 x 4.5 x 1.25. I already had to use some J. B. Weld on the top and sides where a ton of flames were escaping. I also don't have a bottom plate only a bar welded in the middle to hold the bricks in place. I think the problem I had is i tried a few too many different methods and combined them and threw out the hard and/or expensive parts. I'm just trying to heat treat knives that I cut from pieces of weldable steel, yeah i know i cheated. I've seen the posts where everyone suggests those kaowool blankets so that'll be my next step, but should i put them inside or outside or both? tl;dr - I don't know what I'm doing, please help me, I'm broke, too far along, and Christmas is in 13 days.
  8. Seeking advice on a forge for art work

    I am a machinist by trade (although I no longer do that for a living) and I have an interest in adding light duty blacksmithing capabilities to my small shop. Lately I do art work involving lots of CAD design, general machining, CNC plasma cutting, and other general metal fabrication. I have various welding capabilities (MIG, TIG) and oxy/acetylene rig. I just purchased a Peddinghaus 165 lb anvil and leg vise. And now I need a forge! My preference is to buy, not build. I want something self-contained, fairly portable, and safe and easy to operate. My shop is currently in a garage under a house. Could I operate a small propane forge indoors, or should I pull it out into the concrete driveway? Should I pull the anvil out there too? I'm still not entirely sure how practical my plan is. I've successfully done lots of welding and machining in my shop, but not hot work with forge and anvil! These are some forges I have looked at: 3 BURNER MULTI-PURPOSE / FARRIER DELUXE from http://www.majesticforge.com $500 Model 50000 Blacksmith forge from http://www.forgemaster.com/ $775 2-burner MetalSmith Forge from http://www.diamondbackironworks.com/2_burner_metalsmith.html $625 I can justify spending the money on any of these. Any recommendations for a newbie blacksmith who wants to do sculpture / artwork are most welcome. I suspect the heaviest work I might want to do is drawing a 1" diameter bar of mild steel out to a point. Thank you!
  9. Finally got my gas forge up + running! Have a standard 20# grill tank on it and have been considering a larger one but am looking for advice. The 20's are readily available & easily refilled, but don't last real long and can freeze up. Been thinking of either a 30, 40, or 100# size- I like the capacity of the 100, but have a few reservations and would like to hear others experiences.
  10. Flash back arrestor

    Hello all, I am in the process of building my own propane forge and tested it and it work however a friend suggested i look into a flashback arrestor. I just wondered if this was recommended without oxygen being added to the mix. Thank Zack
  11. New forge and burner

    I recently picked up a new forge from a local knife maker to replace my old one. It's a peice of 10" pipe 24" long mounted vertically on 1" plate. He was using it as a salt pot to heat treat in before he built a new one and gave me this along with a Bag of 1" koa-wool insulation to reline it with. For a burner he was using a 2x1 swedge with tubing going through with a hole drilled in the tube. I was wondering whether that burner would have the right atmosphere for regular forging? He had no way to adjust it at all that I could see. Should I make a burner like that or would I be better off using my 3/4 frosty t burner? Thanks in advance.
  12. Getting a Gas Forge

    So I have been using a hand crank coal forge for some time now and have been getting tired of starting and maintaining the fire. I've been looking into buying a gas forge and have looked at Majestic Forge and Diamondback forges. After reading some threads in here I decided magestic was poorly made and couldn't weld easily. I looked at Chile ones too but that is out of my budget. I want to know if any of you have had problems with a diamondback Forge (I want the 2 burner blacksmith model). Or if you think it would be worth my time and money to just make one and buy the burners then any advice on insulation would be great. Also, I want a forge that can do some good welding. I want to try some Damascus in a few months.
  13. Hey there I need some help with hooking up the burners to my forge. Im new to smithing and this is my first attempt at a forge. My forge has 3 trex burners and my goal is to be able to use them independantly or all together. I have researched how the propane distribution block should look and came up with this. Pics attached. My issue is to go from the distrobution block to the burners i need to use flexible copper tubing and to connect it im using compression fittings, the issue is the compression fittings keep leaking ive tried a hundred times and i just cant get them not to leak propane a bit. Is there a special way to do this? Any help would be great. Thanks
  14. Blown propane Forge Question

    Ok so i have looked through this forum for the past two days and i cant find the answer to my question. i am currently planning my first blown propane forge while i am out to sea so i can build it when i return home. I was wondering what diameter of pipe is best used for the mixing pipe that leads into the forge. i have seen people use all the way up to 2.5 in pipe. that seems a little large for me. i think that i will be making the forge out of a 7 gallon or so airtank. i have been thinking of running a dual burner set up mainly for better heat distribution. i would have valves on each individual burner to be able to control them individually. Also is using the precision nozzle like in a venturi burner required for a blown burner or will simply a piece of 1/4in. pipe sufficient. I think i will be building something similar to a peot forge. what is everyone thoughts?
  15. T burner

    I have recently follow frosty's T burner plans and have one problem,my burner will be running good with dark and light blue flames it will suddenly go out and I would have to re light it. any advice on how to fix this would be greatly appreciated, thanks in advance
  16. Burner concept questions

    I was recently looking through instructable and stumbled upon this image and was wondering if it would be a suitable burner for a long and low heat treat/bladesmithing forge? Also here is the link to the instructable. http://www.instructables.com/id/How-to-Make-a-BBQ-Burner/?utm_source=newsletter&utm_medium=email im mostly wondering if it would be able to get up to temperature or what modifications would be needed. I already own a small home built forge so this is strictly outta curiosity. thanks in advance
  17. Burners

    In my previous post I learned that my oddball burners probably would not get hot enough for a forge so now I am wondering what the cheapest burner design that runs on propane is. My forge is 28"x8"x8", and I would also like to know how many burners I should have in my new forges construction.
  18. Hello all, I am going to start building my forge and I am just finishing ordering everything, I have a few questions about insulation. From what I have read, it seems like using ceramic wool is the easiest way to insulate a gas forge, I know it needs to be replaced once in a while because it wears down. Is it best to have 2" of insulation? And are you supposed to line the wool with refractory cement? Or just use straight wool? I know the stuff is bad for your lungs and I was wondering if it lets particles off in the air while it's burning. I plan on laying fire bricks on the very bottom of my forge. Thanks in advance.
  19. I couldn't find this posted here before, so I thought I'd post it up. From Lewis Razors: He has a build video too, the most interesting step of which is hammering the brass (copper?) tube to narrow the ID sufficiently to hold the mig tip. Cheers.
  20. New propane forge build.

    Hello, I've made some progress in building my first propane fired forge. The forge body is 8" id (before insulation) and a length of 12" Lined it with 2 layers of 1" 8lb density Kaowool, followed with some Rigidizer and about 3/8" of Satanite. Installed on the forge floor is a 1" hard fire brick. Burner is a 3/4" running around 5-6psi. I used some soft firebrick as a temporary doors at each end. I couldn't wait to fire it up! I am in the process of building a proper stand for it.
  21. Hi I have just lit up my small home built gas forge for the first time. It is firebrick lined with refractory cement lined with Metrikote. There are some flaking issues with the latter but that is not my question here. I bought the burner online from what claims to be a blacksmithing school here in the USA who make them to help support their business so I figured it was a safe option. I had lit the burner for a few minutes and it was 'on' and there was blue flame visible through the 'ports' you can see high up near the gas connection and a nice roar but the flame coming out of the business end was almost invisible and did not seem to be generating huge heat. I tried heating some very thin stock and it got hot but nowhere near orange heat. Suddenly, and for no obvious reason I could see, the flame 'switched on' and became a roaring pale blue jet projecting down inside the forge chamber. This brought my stock to red heat in a matter of seconds. I then put in a thicker piece (about 1/2 inch square, some sort of small pry bar) and that was at red heat in very short order. I would love to know what changed and how I can get that flame back, I turned the gas off and then lit it again and I was back at the low heat flame, playing with the propane regulator did not seem to make any difference. The burner itself has no adjustments I can see apart from how far into the chamber the end projects (at the moment the end is probably 3/4 inch inside the firebrick - should it maybe be nearer the inside surface of the forge?) Looking forward to any suggestions, I want that flame back Pictures of the burner and the forge in use attached Thanks Dave
  22. Propane torch not staying lit

    I bought a bran new propane torch for 30 bucks. It will be for my gas forge, once I can figure out why it won't stay lit! The torch is hooked up to a PSI regulator, 0-20 PSI. Here is the regulator : https://www.amazon.com/GASPRO-Pressure-Propane-Adjustable-Regulator/dp/B01M4SA4PG/ref=sr_1_16?ie=UTF8&qid=1487707210&sr=8-16&keywords=psi+regulator I turn the psi all the way up and light the torch, and it instantly dies. After fooling around, I figured out that covering the air holes on the burner keeps the flame alive, but burns very slowly, obviously.. The moment I move my hand off of the air holes, the flame goes out. What is going on here?! Pictures of the torch :
  23. Hey Guys. The Edmonton Blacksmith Shop is looking at selling their forge burners separately. They have put them up on their website to gauge interest to see if they will choose to make them available for purchase. I bought their forge and though I haven't used it much (and know even less about forging) it seems quite capable. It would be nice to have a Canadian option for forge burners for those of us north of the border who would like to make their own forge but don't wish to fiddle with burners. I would encourage anyone interested to check them out so they might make them available. This is not intended as an advertisement and I have no affiliation with this shop. I know I looked a while myself for a burner option in Canada before I just bought my forge. http://edmontonblacksmithshop.com/blacksmithing-tools-and-equipment
  24. I recently finished putting together a new furnace made from an old keg. The top and bottom are solid 2700F refractory and the walls are 2" kaowool with a refractory shell. My burner is this Venturi. I took the furnace up to my brother-in-law's farm to do its first firing for curing and ran into a problem that I hope someone can help me with; you may be able to hear me mentioning in the videos, but for clarity the furnace runs great while I have the lid off but when I put it on the flame chokes out, spraying nothing but propane. I have to dial my PSI down extremely low in order to sustain a flame inside with the lid on and it isn't a sufficient heat source to get me to melting temp in any sort of practical time frame. I expect that the answer is simply to continue to fiddle with it further until I have it dialed in, but are there any obvious issues? This is something I would ask about over at Alloy Avenue, but I still haven't been approved for an account; their registration process is peculiar.
  25. hello everyone , at first this is my first time posting here and i am from the netherlands so my english wont be perfect . i watched a video about making a propane burner for my selfmade foundry ( so i finished the build but it does not work like the one in the video here are some photos's and a video of my burner .: so as you can see the torch does not burn right and it burns inside the supply tube aswell.. i am out of ideas what it can be please help video-1477765585.mp4
