DIY Linear Actuator or...

[Rvjimd]

Guys,

I am ready to try and remote/automate the four doors on my lock chamber. I want to try and do something myself for the challenge and maybe to save a bit of money vs buying frigilli brand units or the like. I am NOT convinced that linear actuators are the only or best way to do this but seems like one choice. I have also thought about a curved rack and pinion setup.

I'm looking for ideas. Here is a pic of the open and closed position of one door. I have the zip tie in position for a test of the potential geometry.
