Hi, thought you may wish to see my progress so far.
Posted Image
Alway fancied making one of these and finally got around to it , so out comes the box of scrap metal from under the bench and work began with no set plan. I began by twisting the brass around in a spiral to lift the balls.
Posted Image
The spiral is driven by a small motor and sometimes the ball get jammed and overloads it so I found a good remedy was to place a clutch in the drive mechanism. Anyway got it working roughly and dismantled everything in order to improve the way it looks.
This is it so far.

OK I made a short video as it's not finished and still a work in progress, as you can see I'm turning it by hand . The track was fiddley and took ages, still not happy with it, but it works, just.

Made a support for the motor and polished it .

We were just at the St. Louis Science center and they have a huge area that has rolling colored balls. I took some pictures and was thinking of making something small, but it looks like you already have one completed. I would love to know more specifics of what you are using. Looks great!!!

Hi Phil, it's nearly all from my scrap bin under the work bench, mostly mild steel and brass. The track is made from brass wire purchased from ebay held together with solder and copper wire ( not too happy with the results) and may need changing for a more suitable material. As it's for display on a shelf strenghth is not to crucial. Thanks for your interest.

Welcome Steve! Looks like these projects would take a lot of time to get them to work correctly. Best of luck.

If you have some time check out Andrew Smith's work. He has done some huge ones.

What you have to do is to think that each leg, foot, ear or whatever is a separate sculpture and all together make the finish piece.

Thanks for the video link. That is cool. What are you using for steel balls? Motor? connection to twisted copper? Very neat idea. I saw one on TV last night in a commercial or when the wife was flipping channels or something while I was working on paperwork for today and made me think of this thread.

It looks like a roller coaster I rode on as a child [Punk] I do like the raceway, I know they are quite a project. I think if you've built one you'll probably do another one.

Well done

Love it. Someone, maybe you, should offer a "kit" manual,  instructions for make things like that. Point me if you can.
