I guess the 4 rods running through it could be threaded at the end with counterbored nuts at the end to compress the whole thing together, maybe I could redesign the spacers and the disks so they sort of slide over each other/interlock to improve stiffness of the system.

The idea behind the system is to be more easy to repair/replace sections and to overcome the problems Mouldy had early on with the teeth ripping out (he had to dovetail the teeth in or something I beleive)
