probably be hard to make true. i would say get a cheap big version of a ball castor and hack out the inside roller. that way youve got a strong purpose build item that you need. _________________ www.demon50s.com - Minimoto parts

carbatec is probably about the only place i know of where you could walk into their store and buy them over the shelf. RS is an internet store ($$$$$). _________________ www.demon50s.com - Minimoto parts

Heres an idea just get an inflatable ball use a vacume and such all the air out of it then fill it with resin. Dunno whether it would work but saves all the time of making moulds and when you want to get it out just cut off the plastic. I don't know much bout casting stuff so just tell me if it wouldn't work. _________________ Steven Martin

“The Audi RSQ does not transmit its engine output to four wheels, but to four spheres. They endow the sports coupé with supreme agility and manoeuvrability.”
Is this the sort of thing you had in mind? I was intrigued with the Idea when I first saw the movie Thinking how best to suspend and spin the spheres.
yeah that was kinda thinking.
im not sure about the resin filling of an inflatable ball.

Mabe get them filled with that stuff Jake makes his wheels out of if the ball is strong enough to take it with out distorting while it cures not sure how hot the stuff gets .
Yay i found an alternative to ordering ball transfers, thier so much better too, ring bearings fron the handlebars of two push bikes . Will be making up a mock up of the system soon.

Heres another resin ball idea. Rather
then an inflatable ball, put a
slit in a tennis ball and fill it with resin.
Just squeeze the ball a bit to open the
slit and fill him up. Once its full it will stay
in shape until it sets. Then sandpaper it
once youve cut away the furry rubber skin and ......
Hmmm.....
OR, if you can turn a split ball inside out,
add a little glue so its round again and
THEN fill it with resin ....
It could be a go if you can get the inside
out ball to stay round. _________________ "The future is not set. There is no fate but what WE make."

@ aaron concerning the 3 wheel idea from first page
the idea is good strafeing would become practally impossible but you could move in diagionals easly enough. _________________ as a shadow is seen and not heard i am here
