Hi Darkware,

You might like to try the howto on the AW site that uses the particle system to drive a gear which then drives a further gear.

I got it going with the first driving a second and then driving a third gear, great fun, all done with dynamics.

I had the same problem of gears flying off but in the end a bit of tweaking solved it all.

It's on AW 'community' 'howtos' 'dynamics howtos' - I've not given you a link cos it looks a bit like it's got sessionid info in.

Cheers

Ryan
