Where did you source the rack and pinion on the servo, please?

Now that is interesting - looks like it's 3D printed as well .....

I bet you only buy one of any at all, why would you when you have cracked 3d printing?

Points Control, see post #16

My own use of Servo's, the item as in post #62, would give this idea consideration.

I am thinking of some type of RC points and servo is one option, I assume if I have 3 points close together I could use a single Rx to control the 3 servos :)
You certainly can..
Just remember you will need power for the receiver and servo's..

Power to the Rx I assume would around 5 volts dc, but I thought the power to the servo would be via the 3 pin plug into the servo.

It is (normally) especially if everything is local..
However, it is possible to run a single 'control' wire, to more remote locations, with a locally derived power supply. - For example, something derived from a solar garden light.

Hm that sounds good, points that only work in the sun. Currently cloudy and I am looking at 3 solar powered pumps totally inactive just now. However possibly with a back up battery charged via the solar cells when working may be fine.

Phil, I assume that is the top "signal" wire :)

That would only work for people who are "fair weather" modellers - oh, that'll be me :)

Yes, the 'top' signal wire..

I would make the installation such that the electronics could be switched off between sessions.. Leaving the solar charging circuit active.

Even low standby current, combined with a little damp, is enough to cause pcb tracks to disappear, over time.

I used a small solar panel connected via a charge controller to a 12V 5AHr sealed lead acid battery, output is via a 5V buck converter.
Power 24/7 to a 5V main power line that I just tap off where required.
