Answer 1

A bit of work, but it would be an excellent project. I think it's excellent that someone would be motivated to go out and learn the inner workings of something rather than just buying it.

Unless you are just interested in a DYI project, you would be covering ground that has already been covered. ( commonly referred to as "re-inventing the wheel" )
Do a search for linear actuators and look at what is available.
