- I make a gas forge using an old propane bottle. In this part, I fit the ceramic cloth, lay the fire-proof mortar, spray finish, and test burn the forge. Enjoy!

Nice video! What is the blue stuff you've sprayed on?
Hi Jonas, thanks.
The Blue chemical is called Rigidiser but there are other brands available.
Here's what the website says;
"Rigidiser is a liquid applied to the surface of Kaowool/Isowool, or other high temperature ceramic fibre insulation by spraying or brushing. After air-drying, the rigidiser hardens the refractory ceramic fibre, giving it tougher, more abrasion resistant characteristics. This will also keep it in place against the roof and walls of the forge."
How this helps.
Jim.
Thanks mate. I'll search for a similar product in germany. Cheers
Awesome, good luck.
I was wondering the same... dose it matter if it’s not blue?
Nah, just search for "Ceramic Fibre Rigidizer" and you should find a product in your area that will do the job. Best of luck, Jim.
Video was great, to me it felt professional. Talking was minimal but still very descriptive. Product came out looking awesome!!
Thank you very much. I appreciate your feedback.
Great video! This is my next big project.
Awesome, I hope the build goes well for you.
How did you make your burner like what parts did you buy for it?
Hey mate, I actually bought the gas part from here: goo.gl/uCV4MN
I wasn't confident enough to manufacture my own. THis is the same one that Alec Steele uses in his forges.
Nice stuff mate, looks like the Gameco kit, mate how is that big burner going just got mine today wanted one with some more oomph. I am thinking it will give me more heat. Let me know please what you think of it.???Len
G'day Len,
It is the big burner and it works quite well, although, given my time again, I would've built a larger, box style forge with two of them. It produces good heat nonetheless, bit I just would've liked to have built something capable of more the first time, rather than now, debating whether or not to go through the effort of building something bigger. I don't do enough, I think, to justify the cost and effort a second time around, so now I'm probably just going to keep this.
All in all though, it's great.
@@UrbanSelfSufficiency Yeah mate, the gas bottle forge seem quite big, I suppose you have to decide how big a projects you're going to be making, for me I build my own rectangle forge because at times I have wide things to put in, what pressure do you run the big burner at? Yeah cost is a factor all this refractory cost an arm and a leg.
@@lenblacksmith8559 I'm not sure about the pressure to be honest; there's no gauge, so I just turn the bottle on full, rotated the adjustment knob a little, and had a look... it got nice and hot, so I turned down a little until it "looked" good and went for it. It seems to be working great, so I've never adjusted it since. I only turn the inline valve on the burner to about halfway (45 degrees) and it cranks. Any more than that, and it really blows the heat in. It might heat the steel a lot quicker, but as a novice, I find the control of heating a little more slowly to be more inline with my capabilities; I'm afraid of burning the steel... which I did with the coal forge in my blacksmith class and nearly ruined my knife that I was making. I'll probably get more confident as time goes by and it'll be a better efficiency with gas consumption, but for now... I'm happy.
@@UrbanSelfSufficiency Ok yeah I ended up gettting a gauge Gameco sell them about $40 something. Yeah I used to turn mine on the same way, once you get confident with the pressure and air balance you will get there, I always leave my close off valve fully open and adjust the flame with the gas pressure and air, you will find if you screw the gas reg in you'll get more gas screw it out and less gas, what I used to do before I had a gauge was when ready to turn off turn gas down a bit where it wasn't roaring, and then turn the ball valve off, then turn the tank off. Yeah you can burn the steel alright. Especially in a coke forge.
what is the blue spray?

Hey great video, question though, How much refractory did it take to completely line this?
Cheers. I got the refractory in a kit from Gameco Artisan Supplies Australia. Here's a link to the exact kit (no affiliation)
www.artisansupplies.com.au/product/forge-refractory-kit-9kg-gas-cylinder/?c=22783a5940ef
That link will show you all the measurement/quantities of materials I used.
@@UrbanSelfSufficiency Thank you, and one more question, did you let your rigidizer cure before adding refractory, or did you just let them cure together
@@Danvoodooman10 No, definitely let it cure first. Takes about 24 hours from memory.
@@UrbanSelfSufficiency alright thank you so much
Hey guys late to the party on this one - where did you get the forge burner from and how long does the bbq gas bottle last?
www.artisansupplies.com.au/product-category/blacksmithing-metalsmithing-and-jewellery-supplies/forge-refractory-supplies/gas-forge-burners-and-accessories/
Small bottle lasts hours
Why isn't there a kit like this for sale in the states?!
Sounds like a business opportunity, Zack. lol
Nice one, is that a Gameco burner you're using?
It absolutely is. Keen eye.
Where did you buy your ceramic wool?
goo.gl/wpNbnj
Australia only, I think, though.
Thanks!
Nice build, but why the smaller opening on the backside?
Hey Thomas, that's so I can pass longer pieces of stock through from the front and heat parts in the middle. See here for a visual demonstration: imgur.com/okVsxT1
@@UrbanSelfSufficiency Golly, that was simple enough! Lol. I'm building a forge, not really purposed for metalworking, but for developing temperatures hot enough to test samples of aerated refractory cement, so that isn't critical for my purposes, but one could easily enough be added to the backside of a forge if need be. Thank you very much for clarifying that for me. I have saved your video as a model for my build. I really like the way you did the stand using the angle brackets.
Did you order the wool to fit?
Yes. It was in a pack designed specifically for the 9kg gas bottle. From a company called GameCo
@@UrbanSelfSufficiency awesome, thanks for your help
How large is the opening of your forge
It's about 250mmx150mm or 10"x6"
Urban Self Sufficiency thanks mate👍

Should of coated the kaowool with some kind of refractory after the rigidizer and then coated with metrikote or itc-100.
Any issue with applying these suggestions later? It's been a couple of years since I made this; it's been going great, but if there's no issue with doing this after so many years, I'd be happy to improve the unit if I can, and if you think it'd be worth it. What do you recommend?
Thanks for the feedback, too. I appreciate any good suggestions.
@@UrbanSelfSufficiency i dont see why there would be. I know the metrikote and itc-100 can be reapplied when needed. Its awesome stuff. Helps reflect heat back into the forge really helps to get temps higher and faster. But with the refractory i dont see why there would be an issue but that is something i dont know the answer to 100%.
I am currently building a ribbon burner forge and learning about all the extra stuff that really makes a quality forge.
Awesome, thanks for getting back to me!
@@UrbanSelfSufficiency sure thing. Ive learned that the ceramic coating (metrikote or itc-100) makes quite a bit of difference. Im reading that forging temps come 5 minutes faster in some cases. Less gas for the same temps, which is always good. I should have a completed quality forge by the end of the weekend. Best thing is i have less than $300 in it.
It will have an 18” heating chamber and a 8”-10” ribbon burner.
That's awesome. It's it expensive?

Thank you much
How many of you blew on your screen when he drilled the burner hole thru the fire fiber? yeah me neithe...
Do u think or anyone , that contact cement non-flammable formula works for kaowool????
I honestly have no idea. Kaowool has gotta be cheaper though, right? What's your thinking for using contact cement instead?
@@UrbanSelfSufficiency I'm using kaowool but I wanna use cement on it too,just ended up with this type. Weldwood contact cement . Not sure if it's good tho
@@gomezfun8247 are you using it to coat the kaowool or stick the kaowool to the sides of the forge?
@@UrbanSelfSufficiency coat. It's not rated for the high heat. Definitely going to get something else.
@@UrbanSelfSufficiency thanks for replying! Truly appreciate ,any recommendations for coating kaowool?
You dont tell us what you are doing and why ,not very informative
Sorry it wasn't up to your standard. Thanks for the feedback. I'll try to be better. All the best.
Jim.
