Dining table stand
Table stand has some features common with clock machine. I do not mean putting gears into the stand even though some guys with welder and good access to scrap iron like to make table stands like that. If you take clockwork mechanism than anything which is not connected to measuring time in seconds, minutes and hours is complication. Date or moon phase for instance is nice complication of clockworks mechanism. In rougher world of hand woodworking and making table stands complication is the part which does not help the desk fighting the gravity. Do you need some examples? Here you go: drawers are the very basic table stand complication, but you can go further and make up table stand hiding folded parts of the desk for its enlargenment. In this case i complicated my life with just one drawer, which means building sliders i nto the stand.
