Roger Caffin discusses how you can modify and use cheap butane canisters with canister stoves in this MYOG article.Jan 22, 2021 at 3:45 pm #3695110Paul WagnerBPL Member

As an additional note, we have a small one-burner Coleman stove that uses this type of butane for fuel. It DOES NOT work well below about 40 degrees F (4 C). that’s a problem if you’re going to be using this fuel in the mountains, and/or any time in the shoulder seasons or winter.Jan 24, 2021 at 3:18 pm #3695384Rob St. JohnBPL Member

I wonder how many regular canisters made for my stove(s) can I purchase for the cost of a CNC lathe and bits?Jan 24, 2021 at 4:02 pm #3695394
use one of these
transfer fuel from one of those cartidges to an empty canister and then use regular stove
yeah, it’s a problem below about 40 F, maybe down to 32 F. There are techniques for using at cold temperatures
pre covid, I bought cartridges for $1.25 at the Korean grocer. I don’t feel like shopping, so I bought 12 cartidges for $24 from amazon delivered. That should do me more than a year.Jan 24, 2021 at 6:12 pm #3695415
RobPaul is quite right about cold weather. For that you need either propane/butane mixes or some very special tricks. But for summer time at low-to-medium altitudes, it’s fine.
The little adapters Jerry showed work well. But only $2-3 from ebay, delivered. Amazon is NOT cheap!

CNC lathe AND CNC mill, please.
Sigh, yeah, but I already had the CNC machinery from stove making.
OK, a poor excuse. How about ‘having fun’?

Well beyond my capabilities…. are you starting a business making these?Jan 25, 2021 at 8:22 am #3695479Paul WagnerBPL Member

I don’t think that was Rob, Roger. :>)Jan 25, 2021 at 2:33 pm #3695541
Sorry Paul: posting corrected.
Emily: you don’t need one of my modified adapters if what you have is a ‘conventional’ remote canister stove with a screw-thread connector. You just need the ebay adapter.

Great stuff Roger. You cover the loose ends. My nephew in law has a CNC and laser printer, so can have those made. However, I like Jerry’s approach – just fill a Lindle valve canister with the cheap cans (same as I used on my sailboat for years, as cold weather wasn’t an issue).Feb 3, 2021 at 6:51 pm #3697243

Yeah, been there, done that.
The adapter I modified just lets me skip the refill hassles, that’s all.

Liked this writeup. I had good results with the G Works Butane adapter (ebay) and the Soto Windmaster altough the O-ring had to taken out and the diameter just-so slightly reduced with some sandpaper. Use some folding feet to keep it upright. In Japan this was quite useful as the screw-canisters were not that ubiquitous as the wok canisters.Jun 3, 2021 at 9:07 am #3716960
$25 for 12 cartridges, 8 ounces each
and use this for $10 to transfer to regular canister
When you transfer, make sure the notch on the cartridge is down, then the line will draw liquid, not gas. For normal use, the notch should be up.
Yeah, below 40F this fuel starts not working, although these torch lighters work pretty good
1.3 ounces. If your canister slows down because of cold, just put the flame on it down below
(torch lighter idea and using to make butane work at low temps is David’s idea, not mine:)Jun 3, 2021 at 9:09 am #3716961
and, if post covid I go to the Korean grocer, the cartridges are $1.25. At H mart they’re $1.50.Jun 3, 2021 at 3:21 pm #3717025
Yeah, Amazon prices are a bit of a rip-off. Cheaper at local hardware for the cans (AU$5 for 4), and much cheaper on ebay for the adapters.

If they deliver butane cartridges to my house it’s reasonable they have to charge a little more.
$2 per cartridge is cheaper than good butane canisters, maybe $6 each.Jun 3, 2021 at 3:52 pm #3717036
The interesting thing about the cheap Korean ‘butane’ cans is that they do not contain straight n-butane (BP: 0 C). They most likely contain an equal-parts mix of n-butane (BP: 0 C) and iso-butane (BP: -12 C). Whether they contain any propane is unknown. The stuff is not highly refined.

based on the observed boiling temp, yeah, 50% nbutane, 50% isobutane
as has been discussed before : )
the mixture boils at about 21 F so it operates at maybe 26 F – slowly
I was backpacking this winter. 23 F or so. My stove slowed down to useless, so I used the David torch on its side.
