Well, since the meastro spoke, I might take a turn.
Regarding the players responses to the listening test being contradictory and variable. Browns summary on the subject:
Martin Schleske a modern violinmaker who is alive today makes "tonal copies" of some of the finest stradivari and del Gesu violins. He charges a small percentage of what it would cost for an original. As a physicist and violinmaker he has developed some techniques to test and replicate violins. Schleske was quoted by Brown in the dissertation on page 47 to say:

While on the subject of bass back bracing, some colleagues of mine suggested installing what amounts to a single angled long brace, which I have used with excellent results. It's up to our esteemed host whether he wants to post the pics. (Nick Lloyd used this same system in his 2009 Silver Medal ISB bass.) It provides the requisite support for the soundpost, but avoids the cross-grain attachment which makes traditionally-braced flat-backs so trouble-prone.

This was some minor inspiration for some that I have been trying...and just good work to look at. http://www.talkbass.com/forum/showpo...4&postcount=39 I will say I did try one thing Hans did, but with bad results (I had to replace a customers back). He said he did spots of glue every inch or so to allow for wood movement. I did this...and the wood moved...causing a bulge in between two of the glue spots. I won't try that again. |

And, what do you mean by Spots of Glue? Just Glue over the wood or with patches or braces? Ever seen the upper back bend of a Panormo School Bass? |

The wood was plenty dry and about 8 years old. The bass was made in the fall of 08...did well through the winter, and then I saw it at the ISB (June 09) and it was fine...perfect even...I looked it over well as it is the one and only I did with glue spots. We had a record breaking amount of rain in June and July...and it was July when it failed. I suspect the owner let it sit in his house with the windows all open and 80 to 90% humidity instead of running his air conditioner to keep it at a more healthy 40 to 50%. Regardless of his care...it wouldn't have developed the problem it did had I glued the braces normally.
By glue spots...I mean take your brace (This bass had traditional horizontal bracing) and put a one inch drop of glue every 2 inches across the brace. This is a bad idea and one I will not do again. |

Really?

I have seen plenty of natural glue drips inside of a bass that was just sloppy work but I am sure none of it was done intentionally. My Gilkes had just about the entire Back covered in drips from seams being sloppily glued. Arnold made mention that he scraped off about 2 lbs. of glue from the back during the restoration. I am sure it was more like ounces than pounds but either way, the glue was not there to serve any purpose at all. I have one old Italian bass in restoration with the upper and lower braces beautifully scalloped. They are slightly wider than normal but fairly shallow with a slight 'roller coaster' design from end to end. I asked the Luthier working on this particular bass (Nick Lloyd) to leave the original 'bars in place if at all possible. This way I could see if the bass sounds good with them in because we could always replace them later if 'bars are not destroyed blindly just for tradition sake. Glue Drips? Maybe it's some sore of low cost 'sealer' to the wood that a Luthier/Witch Doctor came up with. Leave windows open in the Summer with the Rain and high humidity? Why would any human punish themselves like that and try breathing that heavy wet air. I would suspect he was at least as sick as the bass by that time.. right? |

Haven't you ever watched the New Yankee Workshop Ken?
Naam is always gluing things that way! " ...I only apply glue to the center of the breadboard ends to allow for expansion and contraction of the tabletop." If you don't believe me, a video is available which includes a measured draring. Eric was just applying this concept a little differently, by applying spots of glue to the brace so the back (underneath the brace) could expand in between those spots. There is no glue drips outside the braces. Now he is admitting it is not advisable. |

Yankee workshop? I hope NONE of the Luthiers working on my basses watch shows like that for advice on how to restore an Italian Bass or even a Yankee bass for that matter. Chairs and Tables do not get played. They do not travel around to gigs in varied climates. If you have to watch the Yankee Workshop to know how to fix something on a professional level then maybe that person needs to apprentice somewhere a little while longer. |
