Process Plan generation for building all four machines!

Hello, Greetings!
I am trying to build machines and shredder would be my start point. It would be of great help and knowledge if any one of you could prepare a process plan chart for building these things! When I cover any one of the machine, I would sure share this with you all. May be some production engineer or any enthusiast could help with it!
Thanks in advance
Cheers 🙂
