It seems as though whenever i think that I know every aspect of making a guitar, 10 more pop up out of nowhere.
That is the facinating part of building and I can guarantee that the new things keep on popping out even you have made 10 guitars.
As said by Simon buy Courtnall and go for it. It is a good step by step book with several plans to choose from and a lot of general information about different aspects of luthiery.
Many of us began that way.
Kit or not - your choice, but buy only good tools, medium price is normally ok.
You can also find used, but that takes time.
You can make many of the special tools yourself,
you' ll find ¨how to¨ videos, threads, articles on the internet.
And this forum is a good place where you can ask when
you don't know what or how to do or when things go wrong.
