i never entered my canister burners in SoTM because they are far beyond the casual builders' scope. a lathe and milling machine are required, and very few people have access to them let alone own them themselves.

besides that; if i entered mine then Tony would enter his, and i'd be blown out of the water. i don't think my fragile psyche could handle that level of rejection! ;) :mrgreen:

We could judge the canister entries against canister entries and regular stoves against regulars 8-)

Hi Daren,
V\besides that; if i entered mine then Tony would enter his, and i'd be blown out of the water. i don't think my fragile psyche could handle that level of rejection!
I have already won the stotm comp, I do think it is fair that I win it again.

My stove making and testing has come to a stop at the moment as we are having a record breaking run if hot temperatures, it has been over 30C for about two weeks now and tomorrow it is going to be over 38C (100F) and parts of Sydney are predicted to be over 47C (116.6F) tomorrow.

Darren, If i understand correctly, Annealing is the same as throwing springs in the fire to remove the temper. I found some tubing called Macroline, its used for carrying high pressure gas, up to about 4000psi in paintball guns. It is also resistant to high temperatures so that much is sorted. One last question aimed at the entire board. Is it possible to have a stove with out the jet. will a pinhole suffice with low pressure gas.

I was able to get good results with using low pressure when I made the Ring of Fire style canister stove. When I cranked up the pressure it burned inefficiently dirty/sooty.

That makes sense Zelph, I have found a maintenance kit for the Jetboil stove, it includes a jet,O-rings and piezoelectric igniter. So i have been thinking of buying it, and using the jet. One last stumbling block though, what could i use to attach the jet to the gas tube. gonna use a metal ink refill tube. could i cast the two component into a block of high temp epoxy putty.

Went looking for a butane canister. Found an 18ml "refill" at the local tobacco store. Much smaller than the Ronson aluminum canister. probably on the order of 7/8" dia and 4" long. It's a Neon brand name and is a clear reservoir so you can monitor fuel level. The metal fill nozzle looks to be 0.100" dia or so. I haven't put the calipers to any of these dimensions yet though.
While I was there I also found a "Venom" energy drink aluminum bottle. Wall weight is on par with the beer bottles, but diameter is the same as a coke can, larger mouth and shorter neck than the Bud bottles as well. I'm going to have to try and make a couple of rolled edge VenoMeth stoves.

If you're going to have only one jet and low pressure I think your going to wind up with nothing more than a flame like you would get out of a Bic lighter.

All you can do is try the putty to see if holds. I had a failure once with JB weld that was close to the flame at about 1/2 inch away. The aluminum was conducting heat down to the area that had the weld. I had sanded the area and also degreased with acetone befor applying the JB weld.

The name Venometh sounds European, I like it!!!! :D Sounds like a good project going to happen, waytogo.

Zelph. you have to remember that DarenNs stove only has one jet as well. it's the diffuser at the top that spreads the flame out.
