Thanks Marty.
This is where I got the idea to “not grind” the charcoal.
I don’t want to cut all the pieces and end up with 3/4 of it just burning away. Might not be a big deal if I had a chunker but I might be willing to cut a bucket of small pieces and use other wood to fire the retort.
Another use I could see with the retort would be if making BBQ charcoal using special woods and fire it with other woods. I suppose even making the charcoal from hardwood and firing it with softwood could get better quality engine fuel.
Your charcoal did look a lot nicer than mine does.
