Extremely wind-resistant 4 fuel SUL cooking system
Jan 5, 2022 at 6:33 pm #3736207
Top exhaust with stainless steel mesh spot-welded to the air intake holes. Works with Esbits, alcohol, canister stoves and wood. Boiled 2 cups of 50* F water in 6:32 min. using 14 gm of alcohol. Haven’t tried the other fuels yet.
The .003″ stainless steel windscreen:
For packing, everything goes in the can, the windscreen wraps tightly around the outside of the can and the cozy holds everything in place. This packing system is very strong and resistant to damage or deformation.
3.1 oz set up for Esbit:
The 4.2 oz alcohol system, with ceramic wick burner and 8 oz fuel bottle:
The 4.0 oz canister stove system for a BRST3000T, which includes a burn chamber baffle and canister heat shield:
The wood kit weighs 3.1 oz and substitutes a titanium base sheet instead of aluminum.
The Foster’s can is reinforced with 2 ribs cut from cat food cans, set at 1 cup and 2 cup heights.
When using Esbit or alcohol:
When burning wood:

Nice work David – I know you’ve been working with all of these components for a long time. It’s fun to see it all come together!Jan 5, 2022 at 7:30 pm #3736212Jon FongBPL Member

Very slick, very nice, very light. Great job David!Jan 5, 2022 at 8:05 pm #3736214
Thanks guys. I first started messing around with UL alcohol set ups in 2012, and I don’t know how many thousands of different stove/pot/windscreen I’ve made and tested. I lost count a long time ago. I did the math once and there was something like a million different possible combinations of the various components. So it has been a long process of prototyping, testing, and refinements.
The goal of a very weather-resistant, SUL 4-fuel system came after I bought an MSR Windburner. I love everything about it except its staggering weight, and single fuel option. And if you’re a prepper/survivalist type you don’t want to have to rely on obtaining canisters or Esbits, but you can usually find methyl or ethyl alcohol, and nearly always wood/twigs/leaves. (Throw in one of Jon’s isopropyl burners and you really be set!)
I’ll be doing some measured wind tests and report the results. Just ordered some ethyl denatured with methyl and isopropyl, and hopefully zero petrochemicals. Should be interesting.
Making and testing these cook kits and my saws has basically been a very advanced form of arts & crafts therapy to cope with a ton of personal crises that started 4 years and then blew up during the pandemic, lockdowns, etc. Really looking forward to 2022 and retiring at the end of the year. From my day job as a bankruptcy lawyer. Never from making!Jan 5, 2022 at 8:18 pm #3736216dirtbagBPL Member
Thats sweet!! I too like my windburner but I dislike that it only works with cannister. Would have loved it to to be multi fuel.. even able to throw it on a fire.. which unfortunately is not possible. That set up you created is awesome!!!!Jan 5, 2022 at 8:30 pm #3736218BonzoBPL Member

Very sweet. Much envy.Jan 5, 2022 at 8:36 pm #3736219
I hope to be selling them soon. Working with a local shop to water-cut the stainless steel, and possibly the Reflectix for the cozy too. Also trying to figure out who to contact about making heat-welded cozies to avoid the assembly time and extra grams of the tape.
Also working on an aluminum heat exchanger base to graft the Foster’s cans onto. Almost done building a propane-fired forge, and plan to try some investment and sand casting of these:Jan 5, 2022 at 8:40 pm #3736220Ethan A.BPL Member

David these look fantastic. Alcohol, esbit, gas and wood at this weight is amazing. Well done!Jan 6, 2022 at 9:03 am #3736237dirtbagBPL Member
