After trying a number of things (like beveling down the "teeth" of the dog gear), we switched to this idea.

It is a 1.5" bore cylinder with a 1/2" throw.

It's been a little while since I've seen a mesh-shifter in FIRST, and this is about as close as I've seen recently. Definitely cool, used to be a lot more stuff like this in FRC.
