really cool that yer a yungun and interested in building. there might be hope for your generation after all (hehe). wish I had tried a scratch build when I was your age... one of my lifes biggest regrets.
I like that you are gung ho about building a neck (most folks are afraid of that), and I don't want to discourage you from that at all, but I also know it can be challenging and would hate to see your zest for building get dampened by a rough "first time". With that in mind, I would humbly suggest that you start by building a body. It's much easier... and if you get that right... then go on to build a neck. I would think the experience of building a body would get you a lot of skills that would help you successfully build a neck.
remember - you can spell success without SUCC hehe!
If you go fwd with the neck - great. It might be a bit stressful but with help you should be able to come out ok.
to build either a neck or a guitar... unless you plan to do it all with chisels (ouch!) you are going to need a router. You could do almost every step of that with a router.
the one thing I would say to look out for afa putting a new radius on an existing neck... going flatter you are going to take off a fair amount of wood. generally the finished dimension on a neck is 1/4" thick at the center... and if you take say a 9" radius and drop it down to a 16" radius... you might remove enough wood that it compromises the stability of the neck, or makes the action impossible to get low enough. things to think about anyway!
truly hope for the absolute best result for you and am happy to help all I can.
cheers
