Does nobody use a Plane ! (or is that far too simple and easy)
p.s. I don't use much pearl

What is your preferred one on an acoustic? |

So far 16" although I would like to do a compound radius sometime. |

I like 12" best. No problem with 14" or 16" but it seems a bit easier for my fat fingers to cover the board on a barre chord with 12". Tim |

I like 12. I did a 12 to 20 compound radius on my last one. I don't think you really "feel" the difference, but I've been able to set the action lower on it than any other guitar I've built, too low probably. Something like 070 on the bass and 045 on the treble. I'm wondering if that is due to the compound radius. Bob |

I use a compound 12" to 16" unless the client wants something different. In my mind a compound radius could allow for lower action. The string spacing spreads as you go up the neck, so the radius should spread also. Again, that's the way it works in my mind. As always, in real life YMMV. |

I did mine on my DIY CNC machine, also did a sanding caul. Never tried doing one by hand, but I would imagine that 2 or 3 different radius sanding blocks could get you there. |

If you're going DIY on it then there are some neat jigs that'll do a compound radius. Mario used to use one, as well as some others, which had two pivots. I think I saw a commercial jig that got fed through a sander or somesuch. |

Woody that is very cool. I take it the inner piece has graduated slots as well? |

I think luthiers cool tools has a plan for one that can do compound radiuses. |

I level the fretboard with a .75" sanding block, working from the outside to the center, following the angle of the edge of the fretboard, coming straight in the center and angling back out to the far side. This gives a compound radius, the longer you go, the bigger the difference between the two ends.... |

I don't use much pearl I use a plane. It allows me to quickly get very close to the desired result. Follow up with a couple of swipes with a block to assure everything is true. Dots are added after radiusing and I use a block to sand them flush. -jd |

Every time I try a plane it ends up tearing out chunks at one end or the other. What am I doin wrong? |
