No plagiarism intended
I actually designed it as a featherweight Beta replica (my plan to make a mini-Terrorhurtz was scuppered by some Geordies ) but as the designed progressed, it changed slightly and now boasts, at most, only minor similarities.

Probably just wide enough to fit the axe arm, sprocket and bearings. I'm going for a rotating shaft rather than fixed shaft, so there will be bearings mounted into the bulkheads and the shaft will be secured with the supplied grub screws. This should minimise side-to-side movement.
