I remember seeing such a set up on a EME website. There were 2 linear
actuators one on each side. They both drove separate rack type gears that drove
a single gear that was in the middle. This gear was coupled to the mast. I
looked pretty cool but was probably not easy to build. Unfortunately I am not
sure where to find this. Mike

Hi Danny,
Rack and pinion is mostly for linear motion. I believe a worm gear with
direct drive or a chain drive would be a better choice. Using a worm gear
you have the breaking function built in. Good luck!

I have been intrigued with putting together my own antenna mast rotation
system and wondered if anyone has any info on using a rack and pinion gear
type system in conjunction with a linear actuator. If the rack and pinion
turns out to be too expensive, my second choice would be a chain drive with
the linear actuator.
Thoughts?
