[Stoves] Traditonal Charcola Making Process / retort

[Ron Larson]

Tom etal

Thanks.  I do not recall ever seeing the 1998 version, but do recall the 
2003 entry.

  There are lots more shorter messages in "stoves" from Elsen that one can 
find via a google -

Do you know of any other charcoaler who has taken this natural-draft, 
down-draft approach?

Ron
