    Steve, If you were to become familiar with tuning EBVT (plenty of aural checks once you learn the ropes), you will immediately see the resemblance in the shape of KV1.3. I'm sure even greater resemblance in KV2.1 )I haven't tried that yet though. ...

    Thanks to all for the great advice! After further consideration, I've decided to "farm" this one out. I wouldn't mind doing the work, but I'm not sure my arthritic hands would hold up to the many hours of fine work required for this. I've contacted ...

    As Keith said, if you repeat a single operation at a time on each part the work will go much faster. It also really helps to have quality tools for the job, in this case a good center pin end nipper, Mannino reamer/burnishers and WNG pinning tool. Anybody ...

    Bridge pins are designed to have a clamping effect. The bridge transfers the string vibration to the soundboard, not only from the up-and-down vibration, but the string yanks on the bridge top to create a rocking motion back and forth. Ribs underneath ...

    Theer is one more thing the bridge pins do. They unsure that the strings stay down on the bridge to keep the down bearing.

    Since cristofori was mentioned, he actually had a better idea than merely changing string angle for some hypothetical gain. Cristofori had the nut underneath so when the hammer struck the string, the string would seat or dig in rather than lift off. Hence ...

    At our last chapter meeting, Mike Reiter showed us his method for repinning. He said it takes him about 90” or so per rail (doesn’t include rebushing though). The key is to find the small efficiencies that add up over 88 flanges. If you are going to convention ...
