Just posted a revision to the sketchup file in the 3d warehouse which is more faithful to kingpen's dimensions. I did not put dimensions on everything, because some things you just got to fit on the thing that you are building, and I dont want to take responsibility for screwups. Besides, its a good mental exercise to figure things out. But the basics are there, and you should make sure that everything fits as you go along.
As to making the table with the wings down in the closed position, my intuition is that why mess with a good thing? I like this version. Just think of how blown away we all were when we saw the video. Changing it seems to be rife with possibilities of a screw up... the wings would have to be shorter, which could be compensated with end sliders set at 45, but how do you stop them from sliding open at while at rest? Then you're exposing the sacrificial risers to getting caught on things as you move the table around, and the wings will have to be wider so that the skirt will not get caught when closing it. I just exhausted myself with negativity, and why go through the trouble, when its perfectly good as is? Whoever feels brave, the sketchup model can be modified to your heart's content... please share.
Buenas noches one and all... enjoi.
