[Stoves] Extended use of TLUDs Re: [biochar] Used Tractors...biochar on homestead

[Alex English]

Stovers,
One of my first TLUDs , in the pre modern era, was made with a 
combination of milk can and propane cylinder. I would remove the valve 
and fill with water and cut with a angle grinder until I had a vent 
opening to adequately release any over pressures due to rapid ignitions. 
Detonations are another matter. When cutting with acetylene and oxygen, 
if you momentarily snub the torch and extinguish the flame the gasses 
can fill a closed container and then ignite on an ember with dangerous 
yield. Almost "blew-it" a few weeks ago when lighting a Dasifier. Ka 
bang! Of the three accidents that week, that was the one I didn't end up 
in ER for.

Any how for nostalgia sake, 15 years ago......
