I’ve had some parallel thoughts - although I’ve just divided the table into three parts. You might be interested in my “hold down” thoughts - to enable you to flip the boards over as well.
another development on the same line - you can make custom hold down parts just in one or two sections if you wish, so that you can make your tee tracks on your machine to suit rather than using the commercial ones.
I should note that at the moment, while I’m doing other things - the boards are in three sections but no fancy hold downs yet!
