What happens if you leave a piece of machinery outdoors, don't use it for several months and don't oil it from time to time? That's right - it seizes up. Which is exactly what has happened to the linear actuator on my amateur satellite elevator.
And in trying to free it, I think I have burned out its motor. I should know better :-(
I have manually positioned it to about 30 degree elevation (and disconnected it from its control system) and will see what I can work like that. In particular, I'm trying to download the telemetry from Delfi-C3.
To fix the elevator, I suspect I will need to replace the actuator, which is not cheap and is a big job. Not sure when I will be able to do it.
