- in the old days of Nascar it was 'Run what you brung' , lets make this work! Strangely, if you take two
Rocket Stove drums, and
feed them equal heat through their respective Heat Risers they will, with perfectly balanced systems give off the same amount of heat. The smaller drum will just radiate it at a higher temperature . This is the same thing you notice when a young small child wants to get up in your lap and cuddle Its so enjoyable for you as their little heat engines produce a noticeable higher heat ! Its the ratio between mass and smaller surface area !
You can also set your drum onto the
Rocket Stove base eccentric from the center, bench marked by the Heat Riser, the pinched side will be cooler, the 'opened' side will be hotter, allowing for the Barrel to be closer to exposures on the pinched side . As documented in Ianto Evans great book "
Rocket Mass Heaters"
There is an ill-defined drum that is often called a 25 gal, 28 gal, or 30 gal, but I have never heard of a steel 35 gal drum, perhaps someone you heard misspoke, then again it could be me thats wrong! good luck Allen L.
About the gasket, Ernie Wisner who is a steward on these forum threads claims to have used hand-rolled strings of dough torn from "wonder bread ", but of
course you can't get that any more ! A.L.
