So, my first question would be how is it possible to keep the rails true when lifting it and fixing it to the wall?
Yes that was it first proped against the wall.

Well in my case then the frame is Rock solid and rails setup on the same plane on the floor so when lifted it hardly moved. The bit it did was a simple case of adjusting with packers and plenty of test cuts to get it back true and setup permanently.

If Building from scratch and designed to be vertical then it would be completley differant and I'd probably build a sturdy Sub frame base that supports the Rails which can then be adjusted or shimmed onto the same plane. It's not really Rocket science just takes time and patience and this is why I'm always saying build has much adjustment into machines has possible because it greatly helps at DIY level.
