How to Make a Propane Forge

[@StutleyConstable]

THANK YOU! This is the only forge construction video I have found where the burner nozzle's positioning is actually described. For that, Thumbs Up.

[@bigoldgrizzly]

Absolutely right - cold water not hot. Saw a guy on a construction site 30 or 40 years ago rip off a great lump of this as emergency toilet paper - no one said a word of warning to him and we wept with laughter for the rest of the day. He got his own back a few days later by sprinkling some in all the wellington boots - fair play

[@bbarker5766]

I like how you explained the steps and even included your what not to do as well.

[@ddistrbd1]

I just made the smaller version following your other video with the coffee can forge video, did not change anything at all, well , except the broom handle, lol, I just used a one inch OD metal tube , if I ever need to make a bigger forge, for sure I'll copy this blue one. both designs are simple and you made both very interesting to watch/understand, great editing also, what I like the best is, you go straight to the point, no fluff, very concise and every minute of it has lots of information . two thumbs up .

[@azflynbear]

Combined with the coffee can forge this is an outstanding set is an outstanding primer for aspiring novice metal workers. I will be eagerly waiting for your next episodes. Keep up the inspiring tutorials. This is great stuff!

[@AndrewWorkshop]

Appreciate the comment!

[@chuckbrow66]

Andrew W could you use the plaster of Paris mixture from the coffee can forge instead of the wool? Thanks!

[@noeprado1778]

To help minimize itching you can rub baby powder on your exposed skin to help prevent ceramic fibers from sticking to your skin. Also works great for fiberglass.

[@TheWtfnonamez]

HAHAHAHA you used a pot to mark the circumference! +1 and subbed. I feel more normal now. I have a jar full of coins from different countries... which I use to mark varying curves on knife blanks....and today I used a sticker from a knife supplier to make cut points in a micro furnace. Love your skills, glad im not the only person out there using random stuff to make things work.

[@Vikingwerk]

Its the tried and true design technique of "the radius of this part is whatever round thing was within reach to trace"

[@Redtailedhawk99]

I also got a good deal on a new 7 Gallon airtank. I stripped the red paint and then I cut both ends off and cut two smaller Rectangle doors out of both of the ends and Pop riveted larger hinges for the larger end pieces and smaller hinges for the smaller rectangle doors for the forging. I did this in case I ever needed to replace the Kaowool and Firebricks. I also have Rigidizer and refractory cement to fill around any exposed kaowool. Also used a piece of black pipe cut short in two pieces and rounded to tap thumbscrew holes to hold my hand built double Venturi burners. Which I’m welding on. I also added an extra valve for when I don’t need both burners. I also tapped the existing bottom bracket and welded on a second and tapped it out. Then I took a large heavy cart and filled the top with kiln bricks while having four large bolts protruding up between to mount it through the bracket holes I tapped out on the forge brackets. I also added latches to the larger doors and smaller doors for traveling with it. My only issue is I was supposed to have locking wheels on the cart, but that’s a problem for another day. I’m ordering some 1000 degree paint

[@andrewwilson8317]

Hi there namesake,good work. Built one myself a year ago! Used for heat treating knife blades and standing up well to use.

[@leif-arnenilsen8484]

[@jordy21287]

I think you were on the right track with the door idea.

[@jamesbond1231]

Not bad for a city boy. God it's entertaining watching people that are clueless when it comes to building shit.

[@senatorjosephmccarthy2720]

The forge looks like it works good. I have one of those tanks so might make mine like this. 6: 20, That looks like a fast way to pay off the farm. Water and electricity.

[@RickRabjohn]

Nicely done video and build - congratulations and thanks for sharing!

[@emgiwoodworks]

Nice forge! I do see a hot spot where the propane torch points down. Perhaps it could use a bit more swirl? Still a design worth imitating. Good job!

[@AndrewWorkshop]

Thanks! Yeah I didn't get the angle right but there is plenty of adjustment.

[@bhaynes8877]

like how technical you were

[@rosswitte]

Great video. Once you cut the end off to hinge it, why not just see that part through? Sounded like a good plan and clearly you can do it.

[@ron0126]

Great video. Love how music randomly shows up!

[@fishmut]

ron0126 ...your a effing weirdo. 🖕

[@theapexfamily9493]

I cant wait to make mine bro

[@yertelt5570]

Awesome video!! I think I would have gone with the hinged door or at the very least used the cut off end you had for the door and slid that on and off instead of cutting then filling in big thru holes on both ends. Just seems like less work in the long run. How did the original blue paint hold up? All the other forge videos they seem to spend a lot of time grinding off the old paint and repainting them with stove paint. If that whole process can be skipped then that alone makes this video worth watching. Great job!!

[@markspc1]

Andrew W Good work !!!

[@jonsey3645]

Cool, thanks!

[@bothebassist]

Great build and I am looking to do something very similar with an nearly if not identical tank. Knowing what O2 can do with a little bit of a spark, I have been cautious to get started. How did you ensure your tank was empty prior to cutting into it? I have found some info for other gas bottles but since you had worked with something so similar thought I could get your take. Thanks!!

[@shanecrumb1079]

8:15 oxygen great for the lungs! desired even!

[@LOZBRY]

great forge, you can make the ciment your self for just a few pounds look on you tube sodium silicate mixed with baby powder and aluminium oxide sodium silicate is very easy to make,

[@censusgary]

Andrew, watching this gives me a wacky idea: Could you build a forge from just a roll of that insulator stuff, with a space left in the middle, painted inside and out with the stabilizer mud? Then you'd poke a hole through the wooly stuff for the burner. In other words, could you do without the metal shell?

[@AndrewWorkshop]

It might be possible but I think it would collapse, the metal isn't really there for insulation, just as structure. Wacky ideas is where great ideas start!

[@walllypalafox2977]

¿

[@pxjones63]

Yes, it's possible for very temporary setups. I used to do something very similar to that when welding forging die blocks for industrial forging drop hammers. You had to preheat the dies to 400+ degrees, and keep them at that temperature until you were done working on them. I'd wrap the dies in the ceramic woll to keep the heat in, and used a small gas burner to keep them hot. There times i heated portions to a dull cherry red, and I'm sure I could have taken it higher, but it was already too hot at that point.

[@Lucifurion]

Should always wear full body overalls when working with anything like ceramic fiber and fiberglass. Saves you from itching like crazy.

[@seanherlihy7309]

Ahhhh wet forge great video

[@allg00dus3rn4m3sg0n3]

Nice build, thanks for sharing. I'm interested in making something similar, but more of a coffee/paint can size. Can't wait to see how the next small build works with the wool and imperial brand cement. That's all I can find around here, and I have yet to track down any Kaowool. Subscribed!

[@AndrewWorkshop]

I may not get to that until next year but thanks! Check your pottery supplies places. They may carry everything you need.

[@christopherproulx2683]

Check on line for Satanite it's a high temperature refractory you can use to seal the kao-wool it's relatively cheap and will greatly improve the efficiency of your forge. Also check for furnace repair places or plumbing stores sometimes the have ceramic insulation and sometimes you can get scraps for free like boxes of them.

[@edwardenglish1519]

Very creative! What do you thing about having two smaller burners in the forge to create a larger heat distribution with the same or less BTU?

[@GeckoSurfboards]

Cool!

[@calebblaser]

So what are the benefits to this style forge compared to your coffee can version. I built the coffee can version and am interested in trying this

[@1rustytree]

Great video and explanation! Could you use a Harbor Freight propane burner for the heat?

[@AndrewWorkshop]

Thanks, I'm assuming you mean a weed burner? Probably not as the orfice would be so close to the inside of the forge you might have problems with the propane mixing with air properly. Maybe modifying one to extend the nozzle? The other issue I can see is those burners have a very large flame, maybe too large.

[@1rustytree]

thanks for the quick reply and info!

[@iownslaves]

subscribed.

[@luisermert]

Very nice video i am looking forward to buiding myself one, but i dont have any spare money right now :(

[@brucemcnally3924]

Please wear boots in the shop, flipflops are for the beach. I like your forge a lot, thanks for your ideas

[@theonlytruedragin]

Why didn’t you use Rigidizer on the Kaowool?

[@Bowtie41]

I like it.You gained a new sub! Now that you had it awhile,how did the Furnace cement slurry hold up? I have a couple tubs of it,and if it worked as good as ITC-100,would save me $$$

[@scotthaungs]

Does the ceramic insulation have to be one uniform piece or can you use pieces of the insulation and then apply the ceramic coating? I have some ceramic insulation that I can salvage into making a forge but it's not one uniform piece would that effect the integrity of the forge with applying the ceramic coating slurry?

[@justanothajoe]

Hey man! I've found that if you back your burner up a bit it will stop sputtering like it is in the video. Hope it helps!

[@AndrewWorkshop]

Thanks that helped, notice it only does it after it gets up to temp.

[@justanothajoe]

: ) I built almost exactly the same forge. I used a freon can but our doors are really similar.. honestly I think I copied what you did. I forget but it looks nearly identical. Careful with the borax.

[@justanothajoe]

A little goes a long way and it'll eat your floor up like fire on styrofoam.

[@jeremygerber4905]

So I am curious why you went through the trouble and expense of using ceramic blanket Board when plaster and sand worked well the last time for a simple forge. Sorry if I sound naive for not knowing particulars. The video is great and I love how you take the time to explain what you are doing.

[@cowdough94]

it'll crumble apart after about 8 or 10 good burns...long term cost of all that material is crazy.

[@willianvalentimteodoromosc8818]

gostei muito 👍

[@user-br3mh4zq4h]

Cool video great information. One question do you think I could use one of the helium tanks you get at wal mart to for home use as the shell of my forge?

[@aldosv73]

would you say that this option is better than an all brick one?

[@user-pi3el9rg5y]

What is the difference between the refractory mortar (cement) you used and the ITC 100 ht coating? Seems like you could turn the cement into the same sort of coating.

[@zoesdada8923]

You do two thin coats of itc 100 over the kawool.

[@naadbergeret2715]

hello, could you tell me why did you make 2 openings ? can't you make just one and let the other side close ? thanks :)

[@AndrewWorkshop]

You can but I like having the opening at the back so I can work with long pieces of metal.

[@kentaylor3087]

could you tell me please where to get this fireproof wool you are talking about.....thank you

[@HenatoFarias]

Hey... I'm trying to build a forge... and i can only use those propane cans with a burner on top... but the end of the burner gets REALLY hot, real fast.... would you help me about this problem?? *your videos really helping xD

[@cowdough94]

it appears that your burner is pulsing. you either need more gas or less air, but that would compromise the flame profile. I don't understand why everyone uses a burner design like this. compressed air siphon nozzle works soooo much better and gets soooo much hotter. it also gives you the option if using different fuels like diesel or waste oil or if you have mosquitoes you can use tiki torch fuel! that's what I run 8n my foundry and I can make 2000 degrees all day long no problem. just my 2 cents

[@saifalshehhi4392]

From where you got forge nylon?

[@hardisiahaan4106]

what is the highest temp for this spesification forge?

[@stephanmurphy7947]

Where abouts on the PSH website will I find the kaowool? I can not seem to locate it.

[@QQ-hm4nu]

made it way harder than it should be honestly lol brought up the cost for no reason

[@rudya4210]

How so? I'm new to all this.

[@wellhattedgent4253]

What kind of welder are you using?

[@OztheTall]

What are the advantages/disadvantages of using this as a lining compared to doing the sand mix lining?

[@ohhaiderhowisyou]

The plaster of paris and sand refractory doesn't hold heat very well, and is very fragile. By using ceramic wool, which already has a heat resistance of 2300 give or take, and adding ITC 100, which will help the forge keep heat very efficiently, he has made a more durable, and more efficient lining that he shouldn't have to replace very often. You would replace the plaster of paris and sand lining much much sooner than this, and it's just not near as good.

[@cirelefebure5485]

Good Job buddy! I was wondering if you used glue (sodium silicate) for the wool on the inside of the chamber, then between the two sheet of wool? BTW i will use only Imperial High temp cement for interior lining over my wool. I'll follow on the result... Can't wait to see your next forging

[@AndrewWorkshop]

Thanks! I didn't use anything, just friction fit.

[@nareshmalla337]

over here it is liquid petroleum gas which is a mixture of propane butane and natural Gass.

[@dustywilder1204]

Is it galvanized?

[@Graeck]

How much ITC-100 is required for this project?

[@Mercury_EG]

22:24 have you tried the stove sealer experiment yet?

[@lugnuttjenkins2813]

also wondering if the main chamber is smaller in height and width will the temperature reach a higher temperature

[@Spionato]

Lugnutt Jenkins probaly not because the propane gas burns at a set tempature if im not mistaken

[@choiceblade]

how many gallons is the air tank?

[@PTQ4Q4Q4Q4]

Could you use an old keg or what they keep large amounts of beer in?

[@cowdough94]

it's big and that's a lot of space to heat up...more insulation more everything. $$$

[@nareshmalla337]

instead of propane can I use LPG gas with this setup??

[@dalmatiangirl61]

LPG = Liquid Propane Gas

[@giggidygiggidy4884]

dalmatiangirl61 nope. Liquid PETROLEUM Gas.

[@JustinTopp]

Giggidygiggidy In most cases it is propane

[@grassCrow]

i dont understand how you light the forge without first turning on the propane

[@RoborobsComputers]

Do you have a list of materials and where they can be found?

[@AndrewWorkshop]

I will post something in the description this weekend.

[@AndrewWorkshop]

I bought the hard to source materials from here www.psh.ca/, the rest I found locally at the hardware store. Materials: Airtank or freon tank or propane tank or steel tube (for the container), at least 10" wide ​Kaowool (ceramic blanket) (check local pottery shops) Kaowool board (check local pottery shops) Firebricks ITC-100 refractory or some other type of brush-able refractory. (check local pottery shops) High heat stove cement High heat BBQ paint Steel tube or iron pipe fitting sized for the propane burner Piece of 14 gauge or similar thickness sheet steel Piece of 1/8" x 3/4" steel flat stock Piece of 1" steel square tubing 2" x 10-32 bolts 3/4" coarse thread screws

[@twistedgizmo3563]

is the wool better then sand and plaster of paris? and if so how much better?

[@AndrewWorkshop]

Much better, not sure since I didn't do a comparison but just by my guess I would say at least 5 times better.

[@krelliankruge9993]

did you use a 5 gallon or 10 gallon air tank? it's kind of hard to tell from the video, I'm not good at math and the diameter and length alone don't tell me much :(

[@DavidMartin-il5sb]

so my question is why you couldnt use the sand plaster of paris refractory for this forge as well???

[@chancekiki8488]

David Martin that refractory is shit tbh. That's why you don't use it, it's not that good

[@DavidMartin-il5sb]

oh okay i went and bought everything to make a forge with it cause i have a old air tank in tha garage and a 300 pound propane tank thats just been sitting in the garage i havennt used in over 4 years im a mechanic and have found hundreds of differnt forge plans on youtube if you could point me to the best design for being able to forge weld billets i would really aprechiate it

[@chancekiki8488]

David Martin for the propane burner I would recommend the vide titled "TurnerForge- How to make an efficient propane burner" For the forge I recommend the video "My Custom Blacksmith Propane Forge Build - Start to Finish" by the KZbinr Makin Sumthin From Nuthin. Depending on the length of the tank you might need two burners. I'm a blacksmith and mine forge needs to be able to forge weld so I would use two burners but one would most likely be okay.

[@DavidMartin-il5sb]

Thanks so much I'm a mechanic haven't done any smithing yet but I want to do some blades and eventually a few sword's but to start i will just be playing till I get a feel for it thanks again

[@MakinSumthinFromNuthin]

Thanks My friend, appreciate the shoutout! :)

[@anthonyhenderson2188]

Hi Andrew Did you add up your total cost?

[@RobinsDynasty]

Anthony Henderson I just built one...$10 scrap yard tank, $30 parts for reil burner, $30 high psi regulator and 5ft hose, $80 8ft2 of ceramic wool, $200 welder.....i didn't bother with the fancy door but i did put in a "floating" piece of ceramic wool in the main opening cutting the main opening down to 6 square inches...i have fire brick extending out 4 inches upon which u can lay a small brick to block the opening...i didn't bother with the ICT 100....my burner is angled directly at the fire brick and the wool doesn't burn unless directly exposed to the flame...i did not install a pass thru as the tank is 18" deep and I'm not planning on making any swords...........yet ;)

[@Ejmaas]

How long is it?

[@maltphilistine923]

That's what she said!

[@michaelcalkins8079]

By using forced air with in the torch or not, will that effect fuel consumption and how?

[@Bowtie41]

Good question,I hope it gets answered,as well as does a forced air setup get hotter?Anyone who knows please chime in.

[@michaelcalkins8079]

I think forcing air dose create more heat. Air being a fuel. Almost like the concept behind forced induction in a motor. Turbos and superchargers.

[@alanbuban9020]

That is a reason I went with a forced air design. If you look closely at the first part of the video you will see yellow flame coming out the front door. This indicates a lack of fuel or oxygen mixture into the gas for efficient burning. If you use a blower and a static air mixer it provides for a better mixture of air and propane fuel and burns more of a blue flame which indicates both a 'hotter' fire and more efficient use of your fuel...

[@cowdough94]

I like this guy.

[@PTQ4Q4Q4Q4]

Propane tech how much will last how long, no one can tell me this?

[@bubblehead7680]

Maybe I missed it, but why not close in the back?

[@vcjhunt999]

on mine i opened the end so i could pass bigger items all the way through

[@addaemadzimoyo3497]

Is it really neccesary to have a removable front?

[@AndrewWorkshop]

It's not but it's really hard to build the forge without a removable opening and it allows for ease of maintenance.

[@budmartin8297]

I'm not a safety patrol, but that "wet saw" scared the crap out of me. Water, 120 VAC and sandals? At least make sure you are plugged into a ground fault detect circuit, so the power will be off when they come to attempt to resuscitate you. Thanks for the video. I know we are all responsible for our own safety, I just want to be sure you understand the risk you are taking. Later

[@AndrewWorkshop]

I figured someone may point that out LOL. The saw was plugged into a GFI outlet.

[@emgiwoodworks]

@Bud Martin: You're the type of guy we don't need on youtube!

[@budmartin8297]

Really dude? I'm sorry I cared about his health, is that better?

[@julianbrody6392]

Stay safe. that bit scared me too. If you decide to make another or anything similar I highly suggest you beg borrow or steal a powerplasma cutter. It will make your life so much easier.

[@wileecoyote4116]

saftey troll spotted ^

[@chancekiki8488]

How much did this all cost to make the forge

[@AndrewWorkshop]

Under 200 dollars Canadian but most of the cost is for the wool and ITC-100 and but have enough left over ITC-100 to make 2 more forges.

[@Craz3dApprentice]

Andrew W how much ITC 100 did you use? 1/4 pint? 1/2 pint?

[@AndrewWorkshop]

I think in raw ITC-100 before mixing with water around 1/4 pint.

[@rjhoffman3396]

can u use concrete for a insulator

[@AndrewWorkshop]

Nope! I think concrete will break down very quickly when exposed to extreme high heats.

[@davidsalman8362]

13:08 Vulcan Accepts your Sacrifice.

[@toMrT]

are you shure the pression is 5psi?

[@AndrewWorkshop]

Yep, at times it might have been 3-5 when adjusting.

[@lugnuttjenkins2813]

do I need a hole on both ends of the forge or just one

[@lol49031]

depends on whether you want to be able to forge unlimited stock length(as in part of it at a time)

[@lol49031]

also probably helps reduce the amount of hot gas going towards you

[@lugnuttjenkins2813]

OK thank u

[@GhostCreeper]

you forgot to add "don't do this" with the water and the electric saw lol

[@denniswilson372]

No he didnt...its a masonary saw..its supposed to have water going through it to cut the dust down and lubricate the concrete.

[@daltonwarren9048]

I just built my forge but I got the atlas burner and I can't keep the damn thing lit can some one please help

[@kennyclauw6302]

why do you have a holl in the back you dont see that in other videos

[@AndrewWorkshop]

Venting but mostly for working with longer pieces of metal.

[@darrelcdammann]

why not plasma cut all steel.... cleaner faster..... I use a old coal forge but for travel this would be a great thing to have. I don't think torch be too hard to fabricate

[@AndrewWorkshop]

Would love to but don't have a plasma cutter.... Yet ;)

[@hermesjackle5903]

was that saw thing made for water

[@ACraftsToday]

Good job!! I'm impressed. Would it be a big deal to install a small piezoelectric lighter near the nozzle of the burner, so you could neatly light it up with the push of a button?

[@AndrewWorkshop]

You could add it to the inside of the burner or light it at the intake, the pressure should force the flame to the end of the nozzle in the forge and burn there, I have seen other people light their forges that way but to be honest it scares me. I don't think the if you install the lighter inside the forge it was survive the intense heat. In one of my other videos where I make a propane jet burner, I use a universal BBQ ignition system, it could be adapted here for sure.

[@aldosv73]

OMG!!!!!!

[@hannihooni8402]

It's not a forge, it's a furnace. A 'forge' is the whole workshop and it's equipment where the blacksmith works: FORGE: NOUN 1 A blacksmith's workshop; a smithy. verb (used with object), forged, forging. 1. to form by heating and hammering; beat into shape FURNACE noun 1. a structure or apparatus in which heat may be generated, as for heating houses, smelting ores, or producing steam.

[@RobinsDynasty]

Shut up you idiot...

[@StutleyConstable]

Merriam-Webster online defines a forge as follows: 1 - a furnace or a shop with its furnace where metal is heated and wrought. 2 - a workshop where wrought iron is produced or where iron is made malleable.

[@dalemartin7886]
