Re: SMOT closed-loop roll arounds? (2nd msg)

[Bob Fickle]

Why not just dispense with the ramps altogether, and instead mount the "ball" on the rim of a bicycle-size wheel- using the smoothest bearings you can find, and very lightweight construction?  That way the "return" is free, with less friction than you've got now;  just position the magnets along the rim's path, and  we could settle this close-the-loop question in short order.

So then, stable or not, what was *your* record for number of roll-arounds? Hi Bill, Sorry but I don't have my original notes so I can't give you more info. However when I finish the single ramp return device maybe I'll put it on a web cam. Then you can count the loops yourself ;-) Now it's just engineering effort, time and money, Greg Find local movie times and trailers on Yahoo! Movies. http://au.movies.yahoo.com
