When measuring an existing instrument the external measurements are pretty easy, and using a light inside the box makes it easy to get the brace patterns and widths, but is there an easy way to record brace height, scallop patterns, top, side and back thicknesses. etc without tearing it apart? |

An inspection mirror with a small light on it and a short (half of a 6") scale wedged in the end of a 1/2" dowel rod. It is a pain but I know of no better way. |

You can press Silly Putty up against the brace and pull it out to get a reasonable estimate of what the brace looks like in hieght and cross section. Almost forgot to mention that if you place some plastic wrap between the putty and whatever your measuring the putty doesn't stick to it and thus doesn't distort so much during the removal process. |

You could also make up a little stick, with a disk or small ball (with a hole in it) that slides over the end. Give it a decent friction fit and then put it inside the guitar and set it on the brace at various locations. Then pull it out of the guitar and measure it. |

Use a Hacklinger gauge-if you have a spare $320.! |

[QUOTE=Robbie O'Brien] how about a contour gauge?[/QUOTE] If you do use a comb type contour gauge, make sure it's one with plastic teeth not metal. Colin |

Yes, Robbie. I think the contour gauge might be the ticket for the braces. It could measure thickness and profile. Now how about a cheap method for measuring side and back thickness? |

You can also bring the guitar to a dark room and put a lightbulb into it to measure the placing of the braces, from the outside. Also you can make several distances to put beside the brace and just moving your fingertip to feel if its the right height. Last year I did a complete measure and drawing of an old Masaru Kohno, and you have to be really creative sometimes! Its really fun, but very time consuming... |

Bruce Dickey used tin foil over the braces when doing his measuring on an Olson once. Cut some strips of tin foil and put it inside the guitar, than form it around the brace, than try and pull it out without distorting it. |

Bah, you guys are creating too much work! Just line it up really good and cut right down the center seam on the bandsaw. You can always glue it back together later. |
