What good is a track saw when building guitars?
A good bandsaw is the ultimate luthiers machine, and for everything else that is behind the scenes like making benches and general stuff, it'll do all you'd ever want that a tablesaw could.
A small one will be noisy and a PITA and won't rip stock like what you'd expect from a TS.
The only thing missing might be a router or two.
A few hand planes will do the job for surfacing timber, unless you're making batches of guitars, like twenty at a time.
I had a quick look around for instructional videos, on making electric guitars with mostly hand tools and nothing jumped out at me.
You might be better off requesting a link for a video series or two to get an idea of a sensible shopping list from a luthiers forum like the OLF, or MIMF to name but two.
You say time is your greatest commodity, and have the idea that power tools speed up things.
This is true, but you still need the hand work first,
I'll give you an example, since you seem **** bent on power tools...
You cut out your shape of the template for your guitar parts using a turning saw (strange looking to some, archaic looking saw with rope to tension blade) or a bandsaw, and refine with spoke shave and scraper or with sander.
Flush trim bit on the router will do the rest.
This leaves you with very little amount of material to remove, and now you're intending to learn to use hand tools with no room for error.
Doing things by hand will give you feedback, and experience with the tool you need, and you hopefully will have learned the don't do that again's doing the roughing work, before you go past your line.
Going back to the impression of being in a rush, which I get from your posts,
say you do buy all those powertools.
With the budget you are giving yourself, I struggle to see how you would honestly see value on those tools after an hours use.
Value... as in your greatest commodity.
That attitude many get from a cheap tool with a screaming universal motor, which could die at any minute, is of...
It'll be grand, sher I have seen the tools limitations and already have outgrown it...
I aint spending time working on this machine, as i have a proper machine coming on Wednesday.
and then something goes BANG....
Which cheap,
get you by powertool, will it be?
You have a shed full of things not seemingly good enough to warrant time on making parts for, it could be any of them you have an accident on, and they all could break at any moment.
Let's hope it wasn't involving your hand, as you spent lots of time making the machine safe to use, including making custom guarding for specific things,
and making sure everything including the tool itself will stay put,
even though you're getting a new one on Wednesday.
Make your mind up about what you actually need, rather than want for time saving reasons.
The super dangerous router is the only tool that you would find reasonably necessary, and/or a drill speed wise.
Truss rod slots, pick up cavities, fretboard radius jig use, binding etc..
Everything else hand tool wise for a simple design electric guitar
will be more than quick enough, unless you're making large batches of them.
Another difficult proposal of having to learn how to use another tool, the hand plane with minimal feedback/room for error.
The spiral cut from a rotary tool like a planer or thicknesser will need to be cleaned up with a hand plane afterwards, if you want a better joint, like one would for a guitar.
And guitar sized blanks are about the minimum dimension you could work on with one, and with shorter blanks comes more opportunity to encounter planer snipe for example.
You could prep enough for two guitar blanks at the same time, but if using exotics
becomes an issue with waste from longer stock having the opportunity to warp and become unusable for your purpose.
Somebody here gave away a Jet pillar drill for free recently.
I bought mine for cheap, you don't need to spend a whole lot on one.
As I said I won't give any advice on routers, and all I can say is
you'd be mad to use one without ever using a hand plane first,
(which MAKES you understand "flat" and have a really good grasp of using various reference)
Learn some skills on youtube by watching, just for starters...
The English woodworker, Paul Sellers, David Charlesworth (a personal favourite)
Phil Lowe, Mitch Peacock, Heritage woodworking, Wood by Wright, Renaissance woodworker, Rouden Atelier, Chris Tribe, Rob Cosman instructions only and skipping sales pitch of everything, he's getting ridiculous. older stuff preferred of his, as well as old stuff from Frank Klausz, or even Roy Underhill for a bit of get it done in a few minutes, fun.
Look on this forum for favourite youtube channels in the search.
No point in looking at skills for fitting kitchens, and debates on which domino is best, if you're wanting to do something a lot more similar to
cabinetmaking.
Different equipment and techniques entirely, like a brain surgeon and a hairdresser might both work with heads.
All the best
