yes, i thought about that. if i was to make one for someone else, that's what i would do. i'd just squash the ends so they wouldn't pull out.

Hi Daren,
i haven't tried a deflector plate, but it seems to me that if the stove is running that close to lift off that the only thing making it work is the deflector, that the stove might be poorly designed. i could very easily be wrong on this.
I got the idea of the deflector plate from pulling apart backpacking commercial stove burners (coleman, primus and Jetboil) a lot of them have a deflector plate in the burner heads, putting a deflector plate in my burner head certainly solved a lot of problems that I was having with lift off and yellow flame, you can make up your own mind if your burner needs it. With your skills it should be an easy thing to do.

How stable is the pot stand with a 1.5l pot full of water on it and have you tried the pot stand at full flame for a full boil.

so far, i haven't had any problems with lift off, even with the smaller (0.28mm) jet.
you're right, the d-plate would be an easy build. i've filed it away in the meat computer for future referance.

1.5 liters of water, huh? did i mention i'm a solo guy? :D i'll give it a try. :lol:
if i have problems with the aluminum potstand legs i'll switch them out for s/s.

You guys got my attention when you said slow is efficient. :D

The all famous Supercat boiled 2 cups of water in my aluminum 2.5 cup pot. Fuel used was 1/2 ounce of denatured. Time was 4.25 min.

Bench tested several times under optimum conditions.

The pot can absorb the heat quickly.

The longer it takes to boil under optimum conditions, tthe longer it's going to take under field conditions and in some cases won't acheive a boil because of loss of heat while waiting for the stove to slowly provide more. Something like that ;) :D

i got out a 2 liter pot and gave it a try with 1.5 liters of tap water. for the big 6" diameter pot i bent the potstand arms out to a 4" diameter circle, from the three inch original pattern. the water boiled in jig time with no potstand problems from heat. stability was quite good with the big pot.
i think that having the potstand legs splayed out a bit helps with stability.

Tony;
you can see that i have not incorporated an evaporater tube on this stove. i don't go out when it's cold, so, no need.
once this big pot was boiling i turned the canister over for a liquid fuel burn; just to see if it would do it. it performed just fine. i guess that the aluminum body of the burner makes enough heat to make the evap tube un-nesseccary; un-required; not needed (is there a trick to remembering how to spell 'nessescary'??).

looks good Oops! a Pocket Rocket knock off to be sure, but some thought went into the flipout pot support arms. looks a bit like the optimus crux arms.
