Well, you do start doing a lot of things by hand.....hand saws, lots of sanding etc. I make guitars, but still sand the fretboard with a radius block rather than the sanding jig they use.....and fret slots are sawn by hand.
A router, drill press and maybe some kind of dropsaw are the main ones I use, with a myriad of small hand tools you'd see in most sheds will do you.
