Ken Greenberg suggests:

One thing I didn't see mentioned that you might want to consider,
given all that space. I spent a lot of time on my deck last week
doing assembly and finishing of a fairly large piece of furniture
that was just too big to work on in the shop. Perhaps you have room
for an assembly/finishing table separate from your workbench(es).

This is a good idea. I would like to make it so that it would fold up when
not needed. Has anyone any suggestions as to height, shape, dimensions, etc?
Or perhaps someone would like to share their own design for an assembly
table?
