| Post subject: | side dots and fretboard edge thickness after radiusing |
For side dots I was wondering if there's a way to calculate where to place them so that after radiusing the fretboard they don't end up too close to the surface of the fret board. Especially since I haven't settled on one radius. Or to put it another way, how would one go about calculating how thick a 1/4" fret board will be at its edges after being radiused... |

Radius then put them on. Bam! |

You could use this http://liutaiomottola.com/formulae/sag.htm I just position all the marker dots a constant distance from the bottom surface of the board and assume it will all go according to plan. About 2mm to dot center, so 1mm between the glue line and the edge of the dot (eyeball it... if it looks right, it's as precise as it needs to be) |

Sadly, I’ve spent way too much time on this and there are tools that help (aka Elevate tool), jogs I’ve built, but in the end Dennis is right in my opinion. Even on boards where it’s not consistent thickness all the way down, if the dots are the same distance from the bottom it looks good. Sent from my iPhone using Tapatalk Pro |

It's fairly easy with this calculator https://www.liutaiomottola.com/formulae/sag.htm If you use this for the FB width and radius at the nut, and then for the FB width and radius at the last dot, the difference in the results will give you the taper in the FB. Or of course you could just measure your radiused FB at the edges with a caliper, easy peasy. |
