Dude, why not get yourself on a mechanics course at your local college
I can't for the life of me understand what the hell you are thinking
Spend £s on a shed, strip it down then rebuild it, is that just for knowledge? Buy a zed workshop manual, cos what you learn stripping a shed won't necessarily be the same on a zed.
Anyway, what do you want to be able to do? Are you modding a zed mechanically?
I don't get it sorry
