Gearing up constraingts

Is there any way to effevtivly (GEAR DOWN) a rotation contraint? For instance, lets sya I have a copy rotation on sylinder one… to copy cylinder two…

is there any way I could make it so that when cylinder one rotates 90 degrees, cylinder two rotates 180?

Just curious

(imagine bicycle gears)

nope

though there is an action constraint which can play an action (for armatures) based on the [global] rotation of an object, it is a bit odd

theeth had a demo of it once, I don’t know if that can be found easily
(I am too lazy to search for it)

This? http://www.clubinfo.bdeb.qc.ca/~theeth/CtrlObject.zip
