Yeah I think it's just too wet. Now that it's dryer it seems better. or should I use a 1" hole? (Hence my dislike of top mount burners; though with proper ventilation this is not so much an issue.). I'll be fine tuning today and I think I'll go with the 45 degree instead of on top. Mounted the burners, cut two new mig tips to half the diameter of the tee for an air gap and fired it off. It's pretty hard to get a picture of that though so I put a video on youtube, I'm no expert but turning up the pressure helped mine stable out. 1- What kind of burner does it have? Thanks so much for the help, Thomas. Another issue with people building forges who aren't familiar with burners is blocking off the ports nearly completely to make it get hotter. I sure wish there was someone that lived close to me for some one on one hands on advice while fine tuning. Two most common ways this happens are: 1: not enough ventilation and so the percentage of exhaust products in the ambient air goes up---often a problem in winter as the forge makes such a nice shop heater as it's trying to kill you. I live in Denver. 3- What is the forge lined with? I forged out merchant couplers(thread protectors) to mimic the rough 1:12 taper for the flare nozzles. By You cannot paste images directly. I figured out how to make and tune a "Jet Ejector" from simple plumbing and basic shop skills about 20 years ago. It's cheaper to pay up front and save over the long term than gradually upgrade over time, honest, been there done that, wish I hadn't. I currently have 1" with 3/4" chase on them. Or maybe split the difference with a .030? It resemble those of other t burners I've seen. As a blacksmith gas forge the atmospheric forge is a good starter gas forge. 2- Does the burner go through the top, center?? I will be using this forge to forge stuff and forge weld Damascus. 7- How much restriction is there in the front and back doors? You use the same stuff to judge the burn as with a blown burner. Forget stressing over "I want to make damascus." Side note: VENTILATION---are you getting enough air into the shop? Frosty is one of the few I would recommend regarding gas forges. If I was going to have only one I would get a blower one ( have one of those too ). DIY Forge Burner Complete Parts List; As an Amazon Associate I earn from qualifying purchases. Re: Propane forge burner design and tuning Another good site for info is the Blacksmithing for Beginners page on Facebook.

Elevation (above sea level) has a big effect but being in Florida that should not be an issue for you. The naturally aspirated burner is easily capable of reaching welding heat, and above, but it is easy to "defeat" your burners if you create any "back-pressure" in your forge chamber. I was thinking of putting the new holes directly on top instead of at a 45. The 1" burner is the burner I use. Buzzkill made a good point that I was overlooking: back pressure from the forge. The forge body is round anyway.

Also are you supposed to have it reccessed down in the pipe? IF you want to try and figure it out on your own with the enthusiastic help of random people on the internet have at it, I'll leave you alone. This acts as a restricter plate or choke to reduce the amount of air entering the burner, helping to reach the correct propane to air mixture. What you're trying to achieve is a neutral to slightly fuel rich flame with little to no secondary or tertiary flame envelope. August 2, 2016 in Gas Forges. How long is the mixing tube? My double 1" burner forge is more than capable of heating 46lbs of steel to a white temperature! Ok, I built a Frosty T burner. So yesterday i asked about forges (i did ALOT of reasearch) and I decided to build one with a t burner (actually 2 ). that might explain how to best adjust the forge.

If you've trimmed a .035 tip enough so that it protrudes less than halfway across the openings when viewed from the side of the T and you still have a significantly rich (light blue to greenish) flame then you'll want to try again with a .030 tip. Are Y you using a 3/4"" t or 1" with 3/4" chase? What BlackMetalViking said. (When I relined my blown forge, the gas pressure that worked fine for the previous runs now was too hot and melted a piece that was left in too long...). Putting a 1.5" blown burner on a 12" forge with a 3" chamber will look like a jet taking off no matter what you set the air/gas at. The only difference between what I have and the directions is the 1/8mipX1/4 flare adapters that were available were 90* elbows.

Once you know what you're doing is time to start tweaking things to what suits you best. This burner does take some time to fine tune but it is very efficient; it gets the forge very hot very quickly. In your situation I'd probably be trying the .030 mig tip, but it is possible that you may need to go smaller. (some that don't have a choke can be adjusted by adding a strip of tape or aluminum foil to cover part of the open end (the COLD END) I have about 2" of insulation in my forge. × Paste as plain text instead, × Nothing would stabilize unless I choked it. Set a fuel rate (pressure) and then add air until you get the noisiest burn---that's generally neutral then you can add or subtract a bit of air to get what you want if you don't want it neutral. You can do a lot of heating of metal in this size of space but you do get creative in figuring out how to put odd shaped steel in the forge chamber. Turning the Ts can be helpful in two ways. The plans have the rules of thumb for the ratios to make different sized burners. That doesn't look to be a problem with yours but it is a plus. Use a hand held propane torch to light, and relight, the burner and later to light the forge once the burner(s) are installed.

Professional looking results and easy of moving would make this design a good choice for taking to craft fairs or similar venues for on-site metal forging or glass blowing. At every fuel pressure there is a corresponding amount of air to get the burn *you* want. The burner operates by creating a low pressure in the throat of the burner bell when the high velocity gas stream injects down the throat of the burner. If you have an account, sign in now to post with your account. A relatively smooth, not rough, sound is desired. Display as a link instead, × Atmospheric burners generally have some sort of choke plate that adjusts how much air the burner can draw in. 12-15 lbs of pressure for welding and about 8 for just forging Tony G Indicated a piece of pipe to center, threaded the tee on, drilled, and tapped before moving anything. Torch file sets work best. Blown burners are generally easy to tune. tank plus time gas end hassle. Takes a minute to get going but after a minute or so it's going better. I also want to be able to use the forge upright for melting aluminum and other alloys. Idk, I still have alot of playing around to do tomorrow. And ive been talking to a friend on Instagram and he says 1.25 inch pipe for the burner and 1.5x1.5x1.25 inch tee but it looks like people on here use 3/4 inch pipe for the burner tubes.

The forge is small enough that I can run the burner at under 5 psi and keep the interior at a good working temperature.However, this burner design does work well in larger forges, many large forges even use multiple burners. Pick an established forge and burner design and use it a while. IF you want to try and figure it out on your own with the enthusiastic help of random people on the internet have at it, I'll leave you alone. If you want to bring say 2,000 cu/in to welding temperature then a 1.25" T burner is what you want. For a 12” forge they can be left full thickness. Maybe not though. Interior size is 12 inches long and 6 inches wide 6 inches high. Available in two sizes, 1" and 1/2". To tune the flame of the burner, some metal tape was applied to the bottom of the burner tube.

I really want to see some pics please. Since glass blowers use copious amounts of gas and efficiency is paramount, I was immediately curious … I'll get an update and post back later today, Alright. Perfect! By color and secondary flames it's burning pretty rich trim the jet back farther about 1/32" at a time and remember to clean any burs from the hole. Pasted as rich text. I used a milling machine to drill the holes in the tees. I'm going to drag up this dead thread to seek advice on my build.

Choked it was very stable through the whole range, but it lacked "fury" if that means anything. I'll take some pics today when I get to work. I bought some hard bricks yesterday to make a little bench too cubby forge to make some stuff to hopefully sell at a craft fair coming up next month. :mellow: Burner Mounting: The Nanomongo burner, or T-Rex, produce such intense vacuum and gas stream pressure that they can be mounted horizontally along the base mounting structure of the forge, and a supply pipe run up to a short nozzle mounted in the forge shell. Test it IN the forge, the confined volume effects back pressure and combustion air induction, they perform differently in or out of the forge. Don't know about the Diamond Back, But I have a 2 burner knife makers forge from NC Tooling and it works great , even for welding. Depending on if I have both ends open or not it will occasionally fall out of tune where the flame goes out and the gas is ignighted my the other burner. A PERFECT example of why you should NOT consult people in the internet. read the instructions for T burners as posted by the person who invented them ( AFAIK ) and has been making them for 20 years rather than taking advice from those who have made 1 of them.

If you want to build a T burner search out the Illustrated burner plan here on Iforge and STOP talking to other people. If I add more air(or choke less) the flames go out. For knifemaking I often run a bit reducing to lower scaling and decarburization---however this also increases CO production so VENTILATE! Remove any constricting rim or rough projections in the throat with a round file. I have to choke one side completly off and almost 20% of the other side to get it to stabilize. Ribbon Forge Burner Instructions by John Emmerling About five years ago, a glass artist purchased the building next to mine and set up his glass blowing studio. If it's positioned such that some of that air containing exhaust from the forge can be drawn into the burner and so re-run through it----CO production will SPIKE. What pressure are you running at? Secondly they wont be fighting each other for air. Use at least 2" of insulation around the chamber: The first inch or two should be Kaowool - the outer layer can be pearlite or vermiculite. A forge built with a Freon Bottle supplies this. I need forge welding temp!! Remember that CO is cumulative in a leaky bucket system---you can build it up faster than you get rid of it. Once you know what you're doing is time to start tweaking things to what suits you best. I would recommend a max of 250 cubic inch forge for the 1" burner.

Blown burners are generally easy to tune. I trimmed it all the way down to about 3/8" from the face of the brass fitting. So every winter we start hammering on folks that while the gas forge makes a closed shop nice and warm; we would prefer to argue with you on IFI rather than attend your estate sale. However if you're having to choke that much there's something else going on, it shouldn't be inducing air that strongly. 4- What propane pressure are you running it at? If for whatever reason you cannot find the parts but think you can replace them with something similar, ask before you buy (include pictures if you can). Just a start of the questions!!! By Are you tuning in or out of the forge? The first step is to align the the jet tube to inject the gas stream directly down the center axis of the bore of the burner tube. I tried trimming it down (in vain) thinking it needed more space to mix and more air. You cannot paste images directly. What is a torch file set? There are some dirty workarounds (not many) And again, printing the parts list and taking that to the hardware store will is a grand plan. In use the burner sucks in air from around it. Your previous content has been restored. In order to build this forge burner… is it in fact better to use a .025 tip opposed to a .035 due to the altitude? The brick have me a good flat surface. I like to tune them when it is dark, because it is easier to see the flame and different colors. Atmospheric or Blower motor Thomas thanks for the explanation. Also does it really matter where the holes are placed? after fiddling with that for quite some time(including trying .030 and .045 mig tips since I had them) I finally pulled the gas apparatus out of the burner, pulled the tee off the end and held it in place in the burner tube while a few assistants helped with lighting and manning the gas valve. remember 95% on you tube is rubbish and at least 50% is dangerous rubbish so check with those who know and are well known for knowing what they are talking about. To tune a Side Arm Burner you will need to remove it from the forge and work with it open air. Reducing will have a bit of unburnt gas in the exhaust plume that will burn as it hit open air. One thing about top mount burners is that they often put out more CO as they can re-run the exhaust that rises as it comes out of the forge.
