Well, there is always the skill factor.
I've never done anything of this magnitude before so I had to gather all of the tools I needed prior to the project. On top of that I'm a light weight with very little muscle mass
So the entire experiance was tiring from just fatigue of holding wrenches, bolts, axles, or whatever in pace..
I'm guessing if you've done something like this before then it'll be quick and easy. But for me this was a first time experiance so it took a lot longer
