How to make a rocket stove with folding legs all on the ground

Making a rocket stove with folding legs and removable pot support
I've seen a few rocket stove builds but never felt the need to build one until camping overnight in an area with only little sticks for firewood, I built it this way to keep it compact.
It works fine without a lid for the stick hole or an inlet air damper, but these can be added later if required. It only took a big handful of sticks to bring a pot of water to the boil and cook some 3 minute noodles, but did take some stoking, a fire grate would probably help.
Unfortunately my local steel supplier didn't have any rusty tube, Vinegar is excellent for removing the zinc coating, but limited time and vinegar meant I had to grind it off near the areas to be welded.

Damn bro ya really marked down the time stamps

Dios te bendiga muy bueno el vídeo saludos cordiales desde Venezuela

[@Darkarious773]

Ok the ramen got you the like!

[@scottmurphy4946]

Came for rocket stove porn, was not dissappointed. Good job with speed up and no annoying as hell music !

[@lapislignum]

Cheers!

I would jump from the bridge if I made a weld like at 5:23. Try a 6013 rod for starting out, and especially for face welds on tubing. It is not aggressive and can be dialed in for work even on very thin sections. Try a full contact to the metal and weave the weld with a U pattern.

[@lapislignum]

yeah that one is extra ugly. I was using 6013 rods, I got some 7016 rods which seem easier to use, i'd get 7018s but they are expensive or a bit tricky to find here.

[@RRaucina]

@@lapislignum If using a AC welder, buy the 7018AC. Otherwise they don't work well. Your voltage on the 6013 must have been low and the rods damp.

[@lapislignum]

it's DC, haven't measured the voltage. The rods were pretty dry, i'm just a rubbish welder.

[@RRaucina]

@@lapislignum You can aspire to greater heights!

[@SamSamuylik]

@@lapislignum atleast your welder gets hot enough. My harbor freight $90 spaghetti box just leaves a worm on top of the metal😂

Todo iba bien hasta que comenzó a soldar

[@lapislignum]

a eso le llamas soldadura?

[@karinasalinas6509]

fíjate en lo bueno, estupidez

It's to high low it down and you see

what?
