There´s an old saying "Only a bad craftsman blames the tools", and this discussion is kind of symbolic of that. There are a hundred ways to do a forearm contour or the multiradius bevel the OP seems to be looking for, both with hand tools and with power tools, and in the hands of a skilled craftsman that knows how to use the tools at hand properly the technique all of them will yield an equally good result.
For ex. someone with many years of experience and just a touch of daredevil might carve necks freehand with an angle grinder (guilty as charged), or they might do it traditionally with rasps and a spokeshave (god that takes forever....)
And the exact same craftsman might do a fretjob with a radius beam, radiused files and an eraser, or he might need some "screw everyone else time" and do the same fretjob the really oldschool way with a bastard file, triangle file, sandpaper and steel wool.
Will the player ever notice any sort of difference if it´s done properly? No.
Does one way save time and therefore lend itself to industrial manufacturing settings or professional shops with high throughput? Yes
but does that matter for a hobbyist that´s doing it to his own guitar? Not in any way shape or form, the important thing there is to make sure the knowledge of how to use the tools is sound, teh mental concept of the final result is correct and feasible, and that both the guitrar and player survive. Everythign else is icing.
And just for teh record, even though I as mentioned do necks and most countours with an angle grinder and have since about 1997, i still teach the traditional hand tool methods first. Because as a professional you will inevitably at some point in your career come across a job that either cannot be done properly with modern time saving techniques, or an instrument that wopuld lose massive value if restored /repaired using modern techniques. For example fretjobs on Compound Radius fretboards are the exact same job as with a flat radius if you´re using anm OG bastard file or beam, but an absolute clusterf* if all you have are modern radiused blocks because that´s all you ever learned to work with.
The important thing (as a profesional) is to keep an open mind and actively explore other methods when they come to light, so as not to see the use of any specific Tool as essential or universally bad, but to understand where and when what should be used in which situation by whom. For example, most 9-5 working people aren´t necessarily going to have a belt sander just lying around... but angle grinder, rasps, files, sandpaper, thatßs much more likely. So while recommending the use of a belt sander might be the generally accepted way to do a forearm contour or tummy cut fast and clean in a professional setting, that doesn´t help the hobbyist that doesn´t want to spend 2000$ on a belt sander and empty half his garage to modify a 100$ guitar body.. . And we that have acces to thse tools and methods sometimes need to remind ourselves of that. :friday:
I´ve seen people hack out pickup cavities with a flat head screwdriver on their personal guitars.... will anyone ever know once the pickguiard is on? No? The fuck it, went faster than settig up the router and still works just fine when all the dust settles.
