Standard bridge procedure includes, scraping off the old DAG, sanding the caps, gluesizing the pin holes, re-notching the bridge, etc. Here's my question/comment. When sanding, the old string groove is not completely removed, but it is minimized significantly. When I'm not trying to alter downbearing, just reproducing what was there (mostly), is that OK? In other words, is leaving a little groove a problem? Is removing it completely more of a problem or more desirable? Y'all have fun with this one. Thanks, -- Jeff Farris Hi, Jeff - I think there is no need to remove the string grooves. Years of pressure from the strings have compressed the wood of the cap slightly to create the grooves. That compressed wood at the bottom of the grooves is very slightly more dense and very slightly more stable than fresh wood. The angled bridge pins have a clamping effect as they trap the strings against the bridge. This effect would be very slightly enhanced by the 'form fit' of the grooves. All these factors are minute, but to the extent they are there, they are probably working in our favor. ~ Tom McNeil ~ Vermont Piano Restorations VermontPiano.com 346 Camp Street Barre, VT 05641 (802) 476-7072 **************Start the year off right.
