4 desktops

I got a request for a desktop with some specific elements built into it. Namely the loop d' loop and the teeter totter. Being able to do both, I said "no problem" and welded one up. And as it goes with these things sometimes, it turned out well, and I received an order for another one immediately after. I took another day, welded up another that looked just the same. But, since it was popular, I sold it to someone else. I know, my bad, but they are family of my machinist, Bill, who has helped me in more ways than I could put into words. So I still had one to make for the previous order I did not fill, and Bill, wanted one for himself. That makes two more. So I thought; why just stop with two? Lets make four! So the last day and a half I've spent making all of the components I will need to assemble 4 new desktops. Oh, and these desktops use 1" marbles. See a picture of the individual components below:

What is shown in the photo is everything I will need, except for the track that will lead the ball from one element to the next. There are the frames, (upper left and right), the loop d' loops, the track splitters (center), tipping arms (right of the splitters), teeter totters (bottom center), and spirals. 4 of each. The one element not shown is the "marbles on track" element. That particular element is added to the track where the ball has enough speed. Want to see what I'm talking about? See the video below of #16. (Thanks Ann!)
