Using 2″ thin wall tubing for the vertical stack and 1-1/2″ for the feeder shoot the stove performed OK, It had a screen on the bottom of the stack.
The ash build-up made it difficult to draw air to keep the flame going, so I cut out a side opening.
It started drawing a bit better, good enough to attempt cooking an egg.
It took some attention to keep the fame going.
Later, I cut the wood shoot off and just fed the small wood chunks from the top. This worked pretty well.
It didn’t take too long to get a small pot of water steaming.
3/16″ by 3″ all-tread bolts act as legs and screw into nuts welded to the base. When not in use, the bolts and folding Cris-cross grill are stored in the main stack.
