It pulls out fairly easily with a pair of wire cutters, and the whole top will screw off for cleaning. I'm going to take one of the nozzle assemblies into work tonight and look at it under one of our 25x stereo microscopes, and possibly a MicroView examiner. I should be able to measure the diameter of the jet in it. I might just enlarge that jet to get a stronger flow while I'm at it. I'll let you guys know what I find.
Good to know about the "bump" :D thanks.

Heres a photo of one being used on a trial stove. Not anywhere near the amount of oxygen was let in using the modified micro torch head.

OK. Took the torch to work. the orifice plate is on the order of 0.085" diameter with a 0.0035" hole in the center. that's 3-1/2 thousandths diameter. smallest drill bit I have is a #81 which is 13.5 thou diameter. A hole with 15 times the area and with flow characteristics included on that would allow more than 20 times the gas flow...way more than I need, or would like. Working on another method of incremental increases.

a new canister burner has come to life here at Neufeld Designs.

i came up with the idea for the burner base/potstand support while stuck in traffic one afternoon and staring at my hood ornament, (i drive an old Mercedes sedan).

the burner assembly, base ring. and potstand legs weigh a total of 27 grams. 3" diameter, 2 3/8" hieght o/a. basicly the same as my earlier vertical burner, it will boil two cups in 6 minutes on 6 grams of fuel. however, the new burner is very stable, eliminating the stability issues i had with the first one.

Nice, very nice. I can see the hood ornament element there. It's cool where we get ideas from to adapt into our designs. Next time I stop at a light I'll look for something to incorporate in to my next stove or whatever.

Your new design looks super stable. Nice rework there. The holes make it look "Tactical" :mrgreen:

a couple of mods to this stove, and two week-long trips useing it exclusively. it's very efficient, useing only 100 grams of fuel on my latest trip of 6 nights.

Congrats, very successful design. Was there anything that came to mind that you might change?

what i changed was, i went to four potstand legs (from three). it's way more stable now. i also changed the fuel input tube so that it curves around the outside of the potstand legs. this allows me to roll the braided fuel line around the legs. the stove will now fit into a three inch coffee cup.
i wouldn't change anything else. it works really well!!
