Absolutely I will document everything. I'd like to have discussions about primary and secondary airflow ratios, etc.

I'd like to see how low a temp I can apply to the top Retort. Lower temp char with more oils left = bacterial food.

Hello Al- Thanks for posting. I have the 30 gallon drums (heavy duty thicker steel) and should have the outer 55 gallon drums this weekend.

I'll post pictures. I wasn't sure if there was any interest.

Thanks!

I started a thread on the Jolly Roger Build I'm about to embark on. Just looking for final thoughts on the various vents and airway dimensions. https://permies.com/t/28553/energy/Build-Jolly-Roger

Appreciate any thoughts!

Hello all-

Building a Pyrolyzer for Biochar production. The Jolly Roger Ovens (JROs) seem most promising before getting into large masonry units. I've attached a file with the design. The basic difference with this JRO variant is the addition of a double barrel to the lower stage. So I'm calling this the JRO-d.

Welcoming any thoughts to this or a better spot on the forum to post this.

Thanks!
