You're not derailing anything Star.
The reason your questions are hard to answer is because there are so many ways to do each little step.
What I did was gather any and all the information I could for a half year or more. I mean I was not messing around about either. I knew I had to have my head together with the best attempt I could make
because I knew if I did it I would be investing at or over $20,000.00 dollars.
When I could build the guitar in my head I invested enough to build one on my patio. It fortunately turned out better than any Strat I own...and I own a lot of them. So I took the plunge and it wasn't to make money...it was to do something I wanted to do and hopeful be able to enjoy doing it for as long as I care to.
I also had to clean the slate for all other hobbies because I knew it would take ALL my free time.
Lucky in a way that the X series hit and wouldn't work for me...cleared that time anyway.
When I found a process that made sense to me for each step I studied about the tools needed to perform it. A technique that "felt" like one I could manage. Those are things that another can't answer for you.
So if you dive off that cliff...maybe best if it's all your doing. That method worked alright with me.
