One night a few years ago i got the idea of making something hot, so i drew up some plans for a blast furnace!!!
The basics: I took a couple of the cans of popcorn my family got for christmas and cut the bottom out of them with a skill saw. I then used them as a base for the refractory mix which is kitty litter boiled to a paste then mixed with concrete sand and gravel. for for the blower I checked out the local flee market with a pair of quarters to purchased their finest hair dryer. the pipe that goes into the furnace is a piece off of a trampoline… the fuel can be anything that burns from oil to coal to wood to charcoal…
Here are some pics of an old mac I figured would make a good show!!!
PS this only took a matter of seconds(like 15)
