I have started a Thread over here on the "Make Your Own Gear" Forum. I am interested in this stove as I like a "remote style" canister stove. I am going to look for an Xtreme stove this afternoon and if I like it in person I will get one.
Collectively (that means all of us putting our heads together) we should be able to move Curts ideas to a dependable solution for a stand set-up. Slick maybe, dependable a must, light a given.
Someting to think about for a good follow-on project might be "What can be make out of the empty canister" ?????

"Canister stoves SMOKE white gas for short burn times, but long burns in cold weather, not so hot no mo."
Side by side on Mount Adams at ~10,000 doing nothing but melting snow, the Xtreme SMOKED a Whisperlite. That was 6 or so years ago. I haven't used anything since that can even touch the Xtreme for snow melting. Canisters are lighter, stove is the same weight as white gas, they're more fuel efficient, and you can't spill the fuel. I've modified one from the original 11 ounces down to about 7 ounces, making it an even better deal. It's the only stove I'd consider for snow melting.

Curt-- can you tell us how you modified your stove to get it down to 7 oz.?
Also, can you figure out approx. fuel consumption for 2 1/2 days based on your winter/alpine experience?

SUBJECT Sleeping Pads to eliminate legsicle fears ON 11/11/2005 15:04:42 MST
Based on everyone's concerns and Ryan's experience, the following Pad system is up for discussion---
Nightlight Torso Pad 3.7 oz. used over Nightlightpad(GossamerGear) 19.5x59x3/4" at 7.5 oz.
Oware pad cut down to 12x24x1/4" at .85 oz.
Last doubled for feet and lower legs.
Total weight is 12.05 oz.
A cut down Nightlight pad could be substituted for
the folding torso pad.
I almost forgot--the small "foot" pad also doubles as an insulation pad for whatever stove system is employed.

Curt is correct about canister stoves, they work best in high altitudes, but if they get cold they tend to die. (has happend to me at about 10-15 degrees) I dont know if there is any canister cozies for sale, I know Bill Fornshell has made one. do you think one of the antigravity gear pot cozys is a comparable size for a canister?
But I still think cooking over fires may be a good idea (it saves all this confusion and mabey half a pound or so, and Ryan is willing to do it!!!!!!)

SUBJECT canister cozys??? ON 11/11/2005 15:32:17 MST
a Anti gravity gear 3cup bowl cozy may work for a MSR 8oz feul canister.(modified)
and a mini solo cozy modified may work for the smaller snow peak canisters
according to Bill you use these in conjunction with a chemical heat pack.

The Coleman Xtreme Stove is a Liquid Feed Gas stove. It is not nearly as subject to cold as the usual Canister type Gas Stove.

You have a fertile mind! You do well in representing the next generation of lightweight backpackers. Maybe you'll follow in Ryan J's, or Bill F.'s footsteps...
Bill's chemical heat pack is key if you want this canister cozy idea to work. Canisters cool from the inside as the fuel evaporates. Without an external source of heat, a cozy would make them even colder.
btw, this is one big advantage to the Powermax canisters as the liquid feed system causes the evaporation (and related cooling) to occur outside the canister. (The other big advantage is that the Propane in the mixture doesn't boil off first.)

Actually, getting it down to just the burner and control valve gets you to 5.7 ounces. At that weight I'd be tempted to choose it over a Pocket Rocket/Snowpeak stove because I prefer the remote canister and the lighter/recyclable canisters.
But, 5.7 ounces includes no stand setup at all and it's a pain to get the cartridges on.
How you add weight back to gain these functions is up to you. I've used a Pocket Rocket 3-leg stand inverted as a stand and it works great - adds an ounce or so. Using tent stakes or a mesh stand that can hold the pot would keep the weight just under 7 ounces.
I'm not a big fan of that setup, though, so I'm working on other ideas. Something that could support the burner and a pot that weighs an ounce or less would be perfect. Very, very possible - I just haven't put the time into figuring it out yet.
By the way, not sure who mentioned it about cartridges in cold, but the Coleman Powermax setup should NOT be considered the same as regular cartridges. It's a different setup altogether. Cut one of these canisters open and there's a metal (brass?) tube inside that runs the length of the cartridge. Not only does this allow liquid fuel to be drawn, but it gets every last drop out of the canister. Empty canisters from use weigh the same as empty canisters that have been punctured and drained.
If Coleman would come up with a F1 Ultralight style stove that used the Powermax system, I'd be first in line to get one.

SUBJECT NEW modified Xtreme--the Curt way ON 11/12/2005 11:53:20 MST
Thanks, Curt. I'm personally intrigued. I would have to get my hand on one to seriously tackle a solution. Perhaps sometime this Winter, I'll do so. Someone with a metal shop like Bill F (if he were interested in the problem) would probably come up with a slick answer.
Any ideas about fuel consumption over 2 1/2 days
(based on the nature of Ryan's trip)?
I wonder if RJ would be interested in using this stove w/ one of your suggested mods for the Winter UL trip?
