 I also cannot tel if the hinges are countersunk or if one set (on each side) sticks up into the "play" surface area.
 
 The hinges do protrude onto the table about 1/16" when it is in the larger configuration.  I plan to build 2'x4' modular table top with various terrain settings on them.  The modular pieces will have 1/8" rubber feet so they can sit above the hinge.  I also plan to store the modular table tops under the table on a yet to be built shelving system.
