Re: Neck Angle Calculator Question
I have an excel spreadsheet that explains this a little better....
Its for neckthrus... but the principle applies...
PM me with your email and I'll send ya a copy.
BUT.. here's the jist of mine... its to calculate the neck angle for the neck WITHOUT the fingerboard on.
When building a neckthru you have to cut the neck break angle at the neck to body join and then install a shim over the body....
but here's how it works..
you take the thickenss of your fretboard, the height of your frets and your string action height, add this together and then subract if from your bridge. This gives you the heigh that the bridge would be if there were no fretboard on the guitar.. This is necessary because the bridge sits on the guitar face, and the fretboard is glued onto it, making the surface of the frets higher in relation to the body... Then the program calculates the angle and gives you a measurment that you use to create the neck drop angle.
The neck drop is the distance from a horizontal line drawm from the guitar face to the nut, that the nut sits BACK from this line. This creates the clearance necessary so that the bridge does not have to be recessed into the body (as on a carvin neck, where there is no break angle)
This guys program works the SAME way..
You put your ACTUAL bridge hieght in and then the program does the subtraction of the fretboard thickness, etc, and gives you the angle you need to make everything work when the fretboard is put on.
His calculator may actually be a version mine, I give it out freely and it was posted years ago on the MIMF....
You want to build a "Fudge" factor into the guitar... you can always RAISE a bridge... but you cant lower it past the surface of the guitar!!!!!!! I use 1/16th of an inch additional bridge height that the bridge actually is!
If this ls clear as mud, let me know and i'll help ya through it!
