    Just got a princess Auto flyer and this camp stove is on sale. Looks like it would make a great base to build a forge from... Thoughts?

    I assume you mean to build a propane forge ? What's it on sale for? website price says it is 150 bucks regular. Not sure how handy you are with fabrication but if you have access to the tools already I would just make one from an old propane tank..those are usually free. 150 bucks would then get you a new, full 20 pound tank ,hose and all the fittings to make the burner and probably a good chunk of the refractory needed. Just my opinion. I am still using my hobo-hybrid brick forge but if i was going to build a new one then i would want it to be split in half lengthwise so I could use a combination of fiber covered with a layer of castable refractory and IR coating.

    It's 10 x 18...so assuming two inch thick of insulation inside and on the back that would bring you down to about a 6 inch diameter by 16 inch long forge at about 450 cubic inch volume. I think thats about right for your standard 3/4" venturi or T burner. It would probably be not a bad little unit for knives if you wanted to spend the money on it.

    And if you meant for coal then don't read all that stuff you just read.

    It will be on sale for $89.00. I definitely would not be a buyer at the $150.00 regular either! I would be doing it as a propane forge for sure if I do it. Watching what a lot of people do online I think it would be pretty simple to find a tube of appropriate width and insert it just to take up the space and pack the refractory around it and remove the tube. I don't think splitting it would be necessary.

    No it wouldn't be necessary at all...I am just going off of what designs I have seen that I liked the most but they were not designed specifically for knives. With the two piece hull it is just easier to get your refractory lined and apply whatever kiln wash and coatings. Also probably a lot easier to re-line after it wears out. I think the stove is a decent candidate for a good knife forge and it has enough room inside to stick a firebrick in the back to increase efficiency. Have you looked into ribbon burners? They look pretty impressive for the kind of temps that they can output at very low (1-5) PSI .... they are blown but I have heard that those little 50$ shop vacs work well for a blower. Depending on how well they can be tuned for the proper mix for knifemaking I am considering building one for the next forge I build.

    get rid of the chimney, get a piece of post 4 x4 and use that as a your form, center it true the door and pour a mix of sand and plaster of paris around it.
    make sure to rap the 4x4 in plastic wrap so you can remove it once the mix is cured.
    also you will need holes on the side for your burners...drill them out pre cast or after the mix is dry.
    Voilllla!
    cool and cheap gas forge! :D

    Dam I think ill get it to!

    it was kinda fun building my forge. I used the perlite/sodium silicate combo for a lightweight insulation. I haven't done a coating yet but i have the aluminum oxide to mix with the sodium silicate. I'm kind of a nerd so i really dig learning about the various chemicals etc. It was also the first thing i ever welded. Anyway, $150 definitely bought all my materials including the brass pieces and hoses to make the burners and I'm not very thrifty at all. There's hundreds of how to youtube videos on this.

    If you were just buying the stove to hold the insulation then any metal bucket would work too for much less money. Maybe not look quite as good but if it works....

    My vote is make it yourself for the fun aspect of it. Plus, for better or worse, there's something really cool about using tools you made yourself.

    of course a 4x4 post. That's a great idea. I used a piece of 4" abs but then had to figure out how to make a flat bottom for it. A total newb question, is it fine to have the blade laying flat in the forge? It still heats evenly right through the steel right?

    The interior will be hot and transfer that heat to the steel and if there is a temperature difference I imagine it is a small one that can be overcome by simply flipping the part over.

    Best part is if this project does not work as a forge you still have a hell of a way to cook hotdogs in under 30 seconds

    Plus you might get a molten cheese explosion out each end of the forge
