Nice experiment there Wilcox. The biggest reason why the bridge lifts, aside from what John mentioned above that cheaper guitars glue to the finish, is the distortion that happens the top right under the bridge. Particularly if the X-Brace is loose under the bridge wings and or if the X-Brace is not under the bridge wings. That allows the top to distort, and bridge plate, so much that it breaks the bridge glue joint. A failing bridge plate can cause this too.
So in your experiment if you thinned that top or let it sit for many years you would see more lifting there I think. |

If you do I want to ask you to not use pins , place a piece of 1/8" Lexan under the bridge plate as the place to anchor the ball ends and place a stop at the front of the bridge to prevent forward motion and then post the result . Oh yeah , one last thing , if you will . Thin the bridge down to about 1/8" in thickness where the strings emerge from it before the saddle . |

Guys and Gals, I apologize for my ignorance about the term "bridge lift".
Thanks to all of you I now know it is the bridge itself actually lifting off the body. My bridge is solidly attached to the top. As I so poorly described in my inital post, I used an envelope perpendicular just below the bridge and noticed I was able to rock the envelope slightly East and West. Thinking that the envelope should not be rocking atr all, I figured the bridge was "lifting" the body ever so slightly. I had no idea that the body has a radius as well as the neck. My whole takeaway here is that in spite of vague, misinforming information, you reached out to me to try to help, and for that, I thank you. As I visit this site from here on out I'll have more questions than comments or answers, but to all of you, you have made me feel welcomed and I appreciate that! |
