Hi. thank you for all of the comments. I'll have to make it through these after work, but just wanted to clear something up, the tape measure was only used to show that moving the bridge forward would put it closer to 25.2-3".
For measurement and placement I relied on the saddlematic. The placement is based entirely off that and following the instructions here with the compensation of the high E string at .062 and the low E at .156: https://www.stewmac.com/video-and-id...e-saddlematic/ Also, the fretboard was a stew mac pre-slotted fretboard that I bought after I messed up the inlay on the fretboard I measured. I've also measured stew mac's work today and seeing it match their fret calculator. Last edited by jmurret; 09-18-2023 at 04:34 PM.

agreed. I'm confused because where I need to move the saddle to is in front well in front of where the pins come out of the saddlematic. so even if I got the adjustment of these pins wrong, the new location takes them out of the equation.

Thank you all so much for your time. I really appreciate it.
I've updated the photos to show the below measurements with a metal rule: - nut to 12th fret - 321.5mm / 12.6575in - double this to get scale length - 643mm / 25.315in - nut to front edge of high E saddle slot - 644mm / 25.3543in - nut to front edge of low E saddle slot - 646mm / 25.4331in From this, is the following true: - if I double my 12th fret measurement to get the scale length, it looks like it is 643mm / 25.315in. - based on stew mac instructions, my high E should be 25.315 + .063 = 25.378 (currently is 25.3543in) - based on stew mac instructions, my low E should be 25.315 + .156 = 25.4715 (currently is 25.4331in) Do these all seem accurate statements based on the photo measurements?

yikes!
OP: the comparative numbers you just offered...your measurements vary from the theoretical calculations by FOUR HUNDREDTHS of an inch as I interpret them. That's no problem to deal with, or ignore, for that matter. If that is so, then I think any intonation problems are somewhere between minute and nonexistent. I'd be looking to see if I was doing my intonation verification right.

you might be right! oh my. i have strobe tuner around here somewhere that i will verify, but a chromatic tuner appears to show no detectable intonation issues beyond intonating the saddle a little further. thank you for bearing with me. user error! :face-palm

if one is using a fairly new measure made by a reputable manufacturer then push and pull measurements are the same...I've been using tapes for almost 40 years now and the only time I've had issues is when I've dropped it and bent the hook, and I've never seen an error even close to an eighth on an inch, more like a 32nd at worst. And said error was evident when pulling the tape not pushing it

Just to be sure, I've always use the 10" mark as my zero.

Sorry I brought up the tape measure
 I see now. What book or plan or online resource are you using to build what I presume is your first guitar? At this point I simply can say check with that. Typically when building a guitar you have most of this ironed out when you design the X=Brace and the bridge patch. Do you remember taking that into consideration when building? IF so maybe look back to those notes.
