you can never have too many clamps for a First Build.
As someone equally consumed with establishing the perfect bridge position this resource is fantastic https://www.liutaiomottola.com/formulae/compensation.htm
Work backwards from the actual strings/tension you intend to use and then you can establish a bridge position that is accurate enough for any further adjustments to be achievable in the filing of the saddle. You may need to get your digital callipers on the strings to measure the core diameters of the wound strings but it is really worth the trouble. The results are spot on.
yes I do seem to recall a Forum discussion over this one.....
If I really push down on the bottom E I can get an extra quarter-tone (12th fret) so I don't push down there! One forgets that one uses this when playing sometimes and I should be aware of it.
I didn't take much off the frets in the end and felt quite pleased that it was reasonable straight. However, the frets are pretty much full-height and that really makes a difference. I might consider taking them down a tad.
Also, I got worried about the edge where the string takes off from the saddle and how to be really accurate about this. Anyone reading this might think that I have good eyesight and good hearing. Far from it. I have various magnifying instruments and lots of tuners, but I do love guitars.
The URL has been duly bookmarked..... many thanks for that. I get a feeling that it's going to be a two coffee read.
I seem to be here now
This is something for the next build.
Hey folks ! I think it is very easy to get hung up on this - Everyone who has built a guitar using my methods has reported 'almost perfect' intonation - that is good enough for a first build...you can spend a lifetime trying to get it 'perfect' but guess what?
There is no such thing as perfect.
When it comes down to it how hard you press (playing style) can have much more of an impact.
Having said all that - thanks for posting those links! ? Fantastic for those who want to 'go deep' on the theory!
I still prefer to use the same simple tried and tested method we use here in the workshop - as described on my courses. You can make fine adjustments until the intonation is 'perfect' for you (but it may not be the same for another player).
Measure twice, cut once...
No fears Mark, I'm with you all the way.
It's my first guitar and I'm amazed that I managed to build something that actually plays. The "wanting to go into depth' comes from my love of learning and a desire to understand what's actually going on here.
I am reminded of the rehearsal, after I had been playing for a little while, when my mate moved E up a tone and it became F, which became G after a move of two frets. Up until that point I had believed all chords existed in isolation (as shown on the pages of the cheap chord book) and had no idea that there were relationships to consider. I went home that night and it all became much easier.
The guitar build sounds great, though I suppose I do secretly compare it with my more expensive guitars. As my wife always says "why, if there are two routes to chose from, do you always opt for the difficult one?" Answers on a fiver to my home address please.
Yeah..I don't mean to be a PITA...just can't help myself ?
Truthfully - I want folks to understand it is not as difficult as they might imagine...I really believe anyone can do it...
It is not a good idea to over complicate things - at least for a beginner...
But like most things ... the deeper down the rabbit hole you go...the scarier it gets...
Measure twice, cut once...
I can only echo that both of my guitars were very close to perfect intonation once action was set - and both play really well!
Sod it - make tea!
