Looks good, but the cast iron grate looks kinda heavy! (o:

Heh, first try, I put a couple of sugarlump sized bits of firelighter in with the nice dry twigs, and it worked a but better than I thought it would. :o)

Steven, do you still use your Ti version? I have some 0.005" foil now to play with.

The Titanium Goat stuff? What's it like to work with (cutting, folding, punching, etc)?

Been considering some of that for the SqueezeBox and Caldera Clones, and also thought it would be easier to use to make a wood stove than mucking about with cans.

A discussion on OM lead me to some simple maths that reminded me that the optimal burner area for a given burner sidewall area is achieved by an infinite number of sidewall plates, also known as a circle... Then it dawned on me that this could be achieved by rolling up a flat piece of Ti into a cylinder (d'oh!), locked together with tabs like my Caldera Clone.

I think the only appropriate response for that is the US vernacular:

Sweet!

Hi Kevin,
No, it's not the CP2 grade TiGoat sell, I went for something with a bit more rigidity. It's 15-3-3-3 which has a large Vanadium content. It cuts and folds ok with a small bend radius, but is more brittle than CP2. Less deformation when punching and burred edges than CP2 though.

I'm currently experimenting with making a DC spot welder to use with it.

Hi Rog

Where did you get he 15-3-3-3 from?
I have been working 6Al4V - hot. It cracks when cold, and I can't punch it anyhow.

I made up an AC spot welder out of a big transformer rewound on the secondary - works OK but is tricky to adjust for the different metal thicknesses.

Cheers

Hi Roger, a 6' long 6" wide piece turned up on US ebay, and I bagged it. I'll check see if the seller has any more if you like.

Been coming in to work smelling like a hippy for the past two days because of this!

Made two prototypes, still needs a bit of tinkering, but so far I'm impressed.

The first one was with a 840ml can of beans on the outside and a can of catfood on the inside which turned out to be too narrow. Now I found a can in between those two sizes, works better, more space for wood..

Once I figured out that lighting the stove from the TOP is imperative I got much better results. Right now with a very much imperfectly sealed stove I got a good-burn time of ~15 min. It took me a bit to cop on but the idea is simply to build a fire on top of your already filled stove. I've been putting the sticks in vertically to get as many inside as possible and still have air-flow. And I *think* they burn slower this way.

It uses very little wood considering the ammount of burn time you get, meaning you can use it just about anywhere. And no smoke means it's stealthy.

One of my objections is that it's bulky unless you're carrying a pot that you can fit it in to. This is also why I refuse to make it any taller than the can I'm using now.

Another objection is that once the fire burns down, you have to add sticks, creating smoke, and the fire is burning from the bottom again, unless you start all over again. So it's good for a stealthy cup of coffee but not a proper meal, unless I manage to get it going for 45+ mins, but with this size can I can't see it happening. May post pictures soon for all you backwards hicks still using the imperial system to give you an idea of the size. ;)

.. whether to put the bottom of the inner can above the holes of the outer can or a bit lower down? Haven't got enough cans to test this at the moment and me and the dog both are sick of eating beans and catfood.

Mike a drawing I have has the bottom about midway thru the hole on the bottom of the outer can (the drawing is of a actual Bushbuddy- as best the guy could tell)

Was that the sketch I posted?

I think so- thank you if it was!

Rog,
Just saw this...my ti version is long gone. Overuse and lack of construction quality lead to it's demise. I tried a number of smaller single wall versions...even had one that worked sort of well but still to finicky for me. Honestly, esbit is just so much easier to use, for me anyway.

Of course, I have another one in the works...but I have about 30 things in the works right now so it isn't getting priority.

Nice job by the way!

Dragging this thread up from the archives...

Where can I get a pint sized paint can as discussed in these posts? I've looked at Home Depot and a couple varieties of paint stores and nobody seems to carry them.

Also for the quart version, all they have are the coated versions and I think I would like the uncoated version so I'm not burning the plastic lining off when using the stove.

Any direction on finding these would be great!

After the first burn the quart paint can will be totally clean. Pretty minor. For my inner I used a progresso soup can that pressure fits exactly into the base of the quart can and I am guessing is lighter that the pint can.

I will post pics when i can, mine works great.... until you add wet fuel ;)

OSH has both the quart and the pint. Uncoated is not an option that I have seen. I haven't noticed fumes myself.

good luck,

Beautiful! Really polished looking :) I'm excited to find out about the Harbor Freight deep throat metal punch, because I want to re-make my tin can Wood-gas stove in stainless steel (I'm going to use food storage canisters made in stainless). I was not looking forward to trying to punch holes through those containers, but that hole punch looks perfect! The simplicity of design in these Wood-gas stoves really charms me, now I just want to make one that won't rust :)

Thanks for all the photos!

Made with Ti Goat foil, and Harbor Freight punch tool...

"Where can I get a pint sized paint can?"

They are sold at ACE Hardware Stores.

"(I'm going to use food storage canisters made in stainless). I was not looking forward to trying to punch holes through those containers, but that hole punch looks perfect!"

I have had good luck with a UniBit to make round holes in stainless steel.

Thanks Daniel! I'll check at ACE. We don't have OSH around here, so that one won't work...

I am actually going to play around with the pint size can to make a double-wall stove to fit inside my SP 600. I'll follow the J Falk model, but make it smaller. I don't know if it will work or not, but I thought it would be worth a try.

I have also used the uni-bit for drilling holes for the regular J Falk bushwhacker and it works very well. I did figure out that the 1/8" bit to pre-drill needs to be new and/or very sharp. It makes a big difference!

John, is yours a double-wall or is it a caldera cone knock-off? I would like to play around with some titanium and double-wall stoves, but need to get some more experience playing around with cheaper metals before I start carving up the tigoat stuff. That will come soon enough!
