I hope that this little MOC contains enough Technic and isn't too silly for this forum.
On a vaguely serious engineering note; I'd be very interested in any suggestions that experienced Technic builders might have for replacing the cams that I've used. They're 1x2 45deg slope bricks. After long-term use, they detach from the Technic connectors with studs that attach them to the big gear. I'd like to build a motorised model using this technique but the current cams won't sustain it. Any ideas please?
