My sequence is different from Hesh's...
I do the bridge height first - THEN cut the nut. I set the bridge height with the strings capoed at the 1st fret in case the nut isn't cut. You ask why I do the bridge first? Because years of working on cheap stuff have shown me this method works better in case of extreme lack of setup for new instruments where the action is high at both ends of the string. I should add that if you can't get the truss rod straight enough to begin with, you'll just be chasing your tail trying to setup the guitar and get it intonated.
Also - I measure string height at the last fret because I assume the player uses ALL the neck, not just up to the 12th. For acoustics, many folks will ask, "What about the fall away?". I hate fall away because the fingerboard should be all one plane - not two. So I plane out the hump on a raw fingerboard, and if it's fretted - I level them all to the same height if the hump isn't too bad. That is how I get 12 string acoustics to play as well as a stupid low setup on a Les Paul all the way to the last fret.
Also, I have been using the same 6" scale to set action for 40 plus years. I don't use that scale for anything else. My tool & die training emphasized consistency, so that scale is a "known value or quantity". I trust it.
Very cool and I was able to understand your sequence perfectly with your excellent description here Chris.
We are doing some of the same things anyway and what I do is just what I do and one method to get folks for lack of a method where they wish to go.
Both of us take the nut slots out of play when we set action at the saddle/bridge. Chris capos and I cut the slots first using the first three frets as references. Either method will permit the saddles/bridge to determine action height wherever you measure it.
Lots of shops have their/our own way of describing what we see so we can talk to each other in our shop. Sadly though there is no "Loothin language" that we all speak, yet....
Fall away is really the inverse of a ski ramp which is the last thing you want. When Leo RIP invented the bolt-on neck or at least was an early adopter of it the ski ramp was also invented. Much of the time the single most limiting factor action wise on a Fender style instrument with a bolt on neck is the rise in the frets from the 12th to the last. This is a ski ramp. bends and more may fret out on the high frets.
So we mill in fall away which really comes into play and has the greatest value with the bluegrass players like Billy Strings who have a heavy attack and really get the strings lashing out. Folks with a lighter touch don't need fall away. And no one needs a ski ramp which will require the action to be set often higher than desired to clear the high frets.
So on an electric a dead straight neck with no fall away is fine. The real goal is no ski ramp. A dead straight neck on an acoustic would work for my personal attack too but for folks competing with a banjo fall-way is the solution if they hit hard.
The only different between capoing and cutting the nut slots first is when Chris goes back to cut the nut slots after setting action AND if he does not cut them to have the same clearance over the next subsequent fret to the capoed fret his action measurement wherever he measures it will change by some percentage of the variance between the capoed fret and the clearance of the next fret.
How much of a difference is this? Mouse nuts
It's inconsequential in my view.
I posted this because I had two PMs over the weekend asking me about the set-up toot and in both cases the real answer was my method has a sequence to it and is dependent on the sequence for excellent results. So I am driving home if you use my method as per my toot do it in order please or all bets are off. The entire point of the sequential method is when we address something it's now done and will not need to be revisited. This is how I work too. When I pick-up a #2 screw driver that tool hits every #2 screw of consequence on the instrument before it gets put back in its house.... Yeah yeah I know.....
So when we remember that nut slot depth, relief and action measured anywhere you wish are ALL functions of each other it's helpful to do things in an order that takes one variable after another out of play as we work. Hence my sequence and Chris's too we are both working toward isolating variables and then addressing them one at a time.
PS: My most used tool is my 6" engineer's scale too. Mine is a StewMac one that I put self stick 120 paper on the back of it to help hold it in place when I press down and am marking something. The Starrett ones are great too, easy to read for old eyes and I have these in my home shop.
