Flip Face – Latest Mechanism Variant

Fri, 9 Mar 2012

Part of the process of making the revised
Big Gear
experiment is this long flexible rack. It got me thinking about yet another possible mechanism for the flip face project.

I constructed this box with a curved top and a slot…

…fitted a slightly shorter rack into the slot…

…and added a pinion. (With involute gear teeth of course)

With a second side in place holding the pinion, it is just a case of pulling either hand to rotate the axle.

Next, a redesign of the flip-face artwork. As I may have mentioned, it was beginning to creep me out.
