I was not able to make any prototype small bales. However I did figure out how to make a 30 inch bale with near perfect consistency AND how to bale the Johnson grass with nearly all the fibers oriented sideways ( flat side to flat side) rather than longways and wrapped around the core.
In case anyone is wondering about my orientation, it has to do with the direction of travel of the baler.
I got the idea of sideways oriented bales from watching the video that Jay posted on this thread about marsh reed buildings in Iraq.
Now my question is which would be better; fibers sideways (flat side to flat side) or fibers longways (wrapped longways around the core).
