The design and wood working wasnt that long.  Just rasturbated an image to size.  The painting my dad took a ton of time to do since he taped it all off.  The bottom part he finished this weekend and didn't take too long.  It attatches together with swing door hooks so it can be broken down to move, but is "solid" to put stuff on and all.
I'd say the painting was like a 4 day a few hours a day thing, the rest was probably 6-8 hours?
