I think Lindsay Publications has a reprint of a medium size
(1 cord load) charcoal kiln. It's called something like "Making
Charcoal in a Connecticut Kiln" Anyway, it is made from cinder block
and would incur some time and $$ to build but the blocks are stacked dry
and would go up in a day or two. Yields from 1 cord of hardwood could
be around 1000 lbs of charcoal. Takes like 48 hrs to cycle a load. You
could have that acre of 1x1 done in Hmmmmmmmmmm you calculate it. Use
of 55 gal drums would be best for small amounts. Lots of knife and
Damascus smiths would probably buy it up if the price was right.
