Uncle Mud (Chris McClellan) is a natural builder who also does extensive work with Rocket Mass Heaters. In this video series Uncle Mud explains the workings of a Batch Box Rocket Cook Stove installed in a Wofati at Wheaton Labs in Montana.
Note: As of 2021 Paul Wheaton no longer uses Cooker lids as a Batch Box door. Paul says that because the edge temperatures and the center temperatures cool at different rates eventually every lid they have used has shattered so for safety reasons they no longer attempt these type of doors.
