Step 1: What you'll need..
Screw drivers (electric driver/drill makes this more fun)
Pinch/wrecker bar or something similarly thin and strong to prevent you bending your screw driver.
Old blanket to catch splintered wood, screws, scraps and keep the boss happy ;)
Oh, and ear protection (hammering the pinch bar and smacking at the wood from the underside of the table generated a fair bit of noise and caused my ears to ring before I grabbed the 'muffs)
Parts required to make something similar at your place..
A similar table to start with ;) - Something with a fairly heavy base if you are going to make it open up..
Hardwood for the cantilever hinge
Any extra wood required for shelves etc.
Replacement wood for any bits you damage
(I had to sacrifice the top routed edging as it was nailed and glued to the table and the table top)
