Back when I didn't know anything about woodworking, I was taught through multiple sources that the first step was to square up your lumber. The second step was to lay out your joinery and cut them while the wood was still a rectangle/square with squared edges. After those important tasks were done, you do any cutting of curves. Once there were curves, then it was harder to do the earlier tasks. I always applied and still do apply this technique to my instrument parts. If I were making a leg for a Duncan Phyfe chair ( I never have done one) , I would apply the same kind of techniques. The last step would be to cut the curves and shape the legs. If I were making a moustache style bridge for an acoustic, I would cut the saddle slot early on and the last steps would be to shape it and sand it. So my question is this? Why are people cutting out a neck shape as step number one instead of doing it down the line in the process? The same thing holds true with the fretboard radiusing, slotting, and dot holes. I know that there are plenty of ways to do things and the end result is the same, but why make it harder than using your router with an edge guide or a router table? This concept has come up a couple times recently and it seems only a handful of people are doing the truss rod slot early on in the order of operations. If one were setting up a small factory to produce guitar parts, you would want to do things in the most efficient way, and that means breaking down the part into its individual operations and analyze them before putting them graphically in a flow chart. I'm just throwing this out there for discussion, as I'm curious why people do what they do and when.
