How to make an Improved Propane Forge or Foundry Burner Build (minimal tools / no welder)

welcome back to make stuff nation today I'm gonna show you how to make an improved naturally aspirated propane Forge or foundry burner as with my previous design you don't need a welder or any special equipment to make this burner after experimenting with my previous burner I've come up with a few simple modifications that allow you to adjust the airflow and also help sustain the flame better than the previous version for supplies you're gonna need the following items one in a quarter-inch iron pipe coupler 3/4 inch to one and a quarter inch bushing 9 inch 3/4 inch pipe nipple 1 and 1/2 inch to 3/4 inch pipe reducer one MIG tip the smaller the diameter the better this is 0.23 inches to 1/8 inch brass pipe caps to 3 inch sections of 1/8 inch brass pipe nipple 1 1/8 inch brass pipe t 1 2 or 3 inch section of lamp pipe or lamp nipple its 1/8 inch in diameter 1 1/4 inch a 1/8 inch bushing a quarter inch ball valve and depending on your regulator connector type you'll need a 1/4 inch hose barb and hose clamp or a piece of 1/4 inch nipple and a 1/4 inch to 3/8 inch bushing also you'll need a pressure regulator this is a 0 to 40 psi regulator I picked up in my local hardware store and it has a 3/8 inch pipe connection on the end finally you'll need a piece of scrap metal that we're gonna use to make the air flow adjuster we don't need too many tools for this project first we'll need a couple of wrenches an adjustable wrench an eleven sixteenths inch wrench a 9/16 inch wrench a 1/2 inch wrench 1/8 inch NPT tap a 2160 fourth inch drill bit a m6 tap a 5 millimeter drill bit and a drill not absolutely necessary but helpful is a hacksaw Center punch to mark out holes and to file to knock off any sharp edges or burrs I've put a parts and tools list down in the description with links on where you can acquire each of the items we'll start by assembling the body of the burner just put the 9 inch piece of pipe somewhere sturdy and thread on the 3/4 inch to one and a quarter inch bushing just thread it on hand tight and then thread on the one and a quarter inch pipe coupler then we'll turn it around and out on the other end screw on the one and a half inch to 3/4 inch reducer I'm recycling this one from an old burner so it already has some holes drilled in it that takes care of the main body of the burner the next part of the process is modifying this tee to hold the MiG tip you're gonna want to clamp in the vise if you don't have a vise you can use some other clamp and just clamp it down to a workbench then take your file and we just want to grind a little flat spot here to make starting the drills that a little easier now that we have a flat spot to work with you can either use a spring Center punch or a normal punch and a hammer to mark a hole in the center of the flat spot you want to be exactly opposite of the leg of the tee mark it a second time for good measure we can go ahead and drill the hole we want to make sure we keep it nice and parallel with the opposite side of the tee now we can tap the hole we just drilled by putting the m6 tap in the drill and running it through and we can test the fit of the MiG tip that threads in nicely nice and snug oh well that turned out crooked guess I'll have to make another one luckily I have an extra T fitting make sure we're nice and straight this time that should do the trick thread spit well let's see how well lined up we are this time that's much better for the next part of the assembly we'll thread in the piece of lamp pipe into the back of the T you can use a wrench to tighten it up the next step is to drill a hole straight through the 1 and a half inch reducer you can use a 13 thirty-seconds drill bit to do this since I'm recycling one from an old burner it's already done to work on assembling the rest of the burner I'm going to take one of the 1/8 inch pipe nipples and add the 1/4 to 1/8 inch bushing on the end I'm gonna then thread that into the ball valve I'm going to take the remaining pipe nipple and thread an end cap on it take your tee fitting put it inside the reducer and thread in one of your 1/8 inch nipples from one side then thread in the other nipple from the other side once you get threaded in you can tighten them up with a wrench so that takes care the main assembly of the burner now we can get started on the airflow regulator take your scrap piece of metal and either cut it into a square or a circle that's the same size as the one and a half inch reducer there we go we'll just take a file and knock off the sharp edges there we go nice and clean no sharp edges next mark the approximate center of your piece of metal then use your Center punch to mark it now with it mounted securely we can drill our hole with our 2160 fourths trill bit and follow that up with tapping it with our 1/8 inch NPT towel that looks pretty decent now we'll test fit it and see how it fits that looks good with that installed we can install our end cap tighten it on with a wrench now obviously this assembly is still a little bit loose and we want to have it lined up directly down the barrel of the burner we can apply some JB quick weld here on the outside and that will hold it in place this part of the burner shouldn't get too hot because the air flows through it will help keep it cool so we shouldn't have to worry about the temperature I'll tighten this down to align it while we apply the JB quick well I've cleaned up both sides with a wire brush some sandpaper I'm going to hit it with some brake clean before I apply the epoxy it's a little messy but it's really effective there we go that's the second side here we have the finished burner the epoxy is all set up the gas assembly is nice and secure we have our adjustable air flow regulator all we need to do is hook it up and give it a try to hook up our pressure regulator and hose I'm gonna have to use the barbed and hose clamp I initially thought this was a 3/8 inch NPT fitting but it's not it's actually a 3/8 inch flare fitting so it's not compatible I'd have to get a couple more adaptors but I already have the hose barb so I'm just gonna cut this off and use the hose barb instead there that's nice and snow I'll just use some scissors to cut off the fitting I'm not using then slide the hose clamp over the hose and press it on to the hose barb finally use a screwdriver to tighten the hose clamp so here we are the next day the epoxy is set up and fully cured holding the assembly very nice and secure it's not moving at all and then the air flow adjuster bends nice and easily let's give it a test run I've backed off the regulator as far as it'll go so it should be at zero psi this is a minimum pressure on the regulator that's with minimal airflow [Music] this is pretty high-pressure got a nice flame the body of the burner is staying nice and cool I'm gonna shut off the burner by just turning down the regulator well I would say that was a very successful test of this new burner the smaller diameter MIG tip as well as the larger diameter flare helps sustain the flame down at the flare and of the burner where we want it the smaller MIG tip should help the burner also be much more efficient the airflow adjuster will give us much more versatility in the type and temperature of flame that we can use to heat our foundry or Forge as you can see this is a very easy burner to make yourself you don't need any special equipment like a welder you can do it with mostly hand tools I encourage you to go make one for yourself don't forget that I've posted a list of all the parts and some of the tools down in the description if you have any questions or suggestions please throw in the comments down below as always please
