Hi - I'm about to start working on my first guitar, and I've been wondering about the positioning of frets. When you press a string down to a fret the tension in the string is increasing a very little bit so that essentially, it it detuned a bit. I've no idea how much this is, I've no idea if this is a real of a theoretical problem. Anyway, I guess it should be "worst" at the first fret. Now, while calculating the correct fret positions, would you take the mathematically correct positions or should one introduce a compensation for that ? Ludo

I think it depend on the type of trussrod you intend to use. The pressure/forces are depending on whether it's a single or double rod. With a double, you'd need 1/8 at least - with a single bent rod, you could maybe go a tiny bit lower ...
