A while back I actually made a jig that would create a ruled surface irregardless of starting and end radius, producing straight surfaces along every string line. Unfortunately, the jig was nine feet long and impossible to store here in the new place. But I was able to create fretboards that were "compound radius" and with an 8 degree twist, along with the matching twist on the neck wood. And it's actually very simple in design and concept. |

I like the scribe line idea.

I remember that pic in his book. I never had a thickness sander, so I couldn't do it that way. I had tried doing so on the tablesaw, but it required a custom zero-clearance insert for that particular angle. Too old for that stuff...

Wow, this is like Groundhog Day .
And I mean that in an extremely positive way ! Louie and I have been debating conical surfaces for like almost twenty years ... there was an epic thread on the MIMF back in (I think) 2000 where every aspect of conical/compound surface was debated, with Louie emerging the ultimate winner ... but there still remains one small point to be debated ... more later. John (Arnold) if you are still watching this thread there is something I would like to ask. I have a memory of you posting (long time ago) that your method of fretboard radiusing was first of all to establish the nut radius and then use a hand plane to shape the fretboard so that the height of the fretboard sides remained constant, and also the center height from nut to end of fret board remained constant ... the radius at the upper (lower ?) end of fretboard being irrelevant. Is this a fair summation of your approach ? |

I do feel confident that I can make a very playable guitar ... what it will actually sound like is another matter entirely ... |

Sorry Louie, but I am afraid that your recollection is way out ... how I wish it were otherwise ...

I calculate that the "rise" should only be 1 mil for a 10" radius and typical string spacing. Would you mind sharing the method you used to calculate this? |

I calculated .001", but because of these "dumbphones," I apparently missed a zero. This is for a 25.5" scale, with an 18.5" fretboard, 1-3/4" nut, 2-1/4" fretboard end, outer strings 1/8" from edge constant.
