i love junk, upcycling, creating, and fire! I'm sure I'm not alone. I've seen some homemade tent stoves made from ammo cans, store bought mini house
wood stoves which are costly, barrel stoves which are nice in the eye of a recycle'r upcycle'r creator, but very thin material which can easily burn-out. i have access to many old date expired free propane tanks, car wheels, and various scrap metals so i thought i'd try to build something more simple than a
rocket stove, compact and take up minimal floor space (tiny living, space saving,...), and do it by spending very little, and practice welding and fabricating along the way.
my first outcome was simple. safely evacuate and purge the gas, add a door opening and exhaust stack. KISS keep it simple, silly! i ended up using a 5" diesel truck exhaust pipe! i've seen tiny home stoves and pellet stoves with 4" exhaust, i've made rockets and wood stoves with 6", so this 5" heavy duty pipe
should be a great piece to use. the heavy exhaust pipe will extend a few feet from the body of the stove, as a part of the stove. this strong heat rated exhaust pipe can handle the heat if any flames travel up into the exhaust, which i'm sure is possibly inevitable which a small stove.
i'm using a 40 lb LP tank as i thing a common 20lb bbq tank is a bit too compact. this 40 lb tank has more radiant surface area but takes you the same 12" diameter , only 1 sq ft of floor space required either way, but this way allows more capacity, more radiant surface area, and more room for exhaust to funnel, and
ash to build or clean.
here is my first simple setup, i started this last winter as a free-time boredom welding
project, later on i make some modifications to a few things. the cook-top was something i wanted to change for the better. i always liked clean burning fires and lots of oxygen, never intended on building an "airtight" model but i do have a couple new wood-stove rope seal door gaskets waiting, in 2 different sizes.
stage 1, safely convert the LP tank into an upright wood-stove. i consider it to be a vertical barrel stove, vertical for less floor space requirements.
