Amazing round table!

It’s probably done with large threaded rings (brass maybe)
and perhaps some sort of follower arm and linear
slide system.

This video shows the underside of a similar working table.

Jap! great post! there have been several looking for this answer. the fletcher table just adds the center section. The leaves are also made of composite material. they incorporate biscuits and uhmw pockets to maintain alignment.

Laps of memory sorry, the ratio between the leaves and the center and the number of leaves are different. It threw me off spatially. Yea I can be kind of spacey all by myself.

Jap, thanks for that link. what is clear from that, that there goes a LOT more than mere woodworking into that table!

I spent way too much time on Youtube looking at these tables a while ago. The ones that operate manually are still amazing. I think I remember an expanding table in a British museum that was very interesting too. -Jack
