Hi Gene! (I always feel so clean when I can address someone that way!)... I frankly don't see any reason why you couldn't jigger a capo bar. Everything else is jiggerable to some degree or another. There are serious geometries and bearing tensions to deal with, as well as just the structural materials you will use and how you will clamp them in place. But why? Are there problems with the existing agraffes? Personally, me, I like agraffes to the top. And would not redesign for a capo bar. It was Erard's solution to the economics of agraffes, and not a design for the better necessarily. Cheers, Paul In a message dated 2/2/2009 4:54:09 P.M.

Much of the belly work has been completed. It has agraffe's up through note #88. I had considered the possibility of installing a capo bar to replace the agraffes. Either in just the top or top two sections. I am curious if any living techs that read the forum have had experience with similar redesign issues. I have looked at Bosendorfer closely and think that a similar type of bar is possible.

Anyone ever consider doing this? Thanks, Gene ____________________________________ _Great Deals on Dell Laptops.
