Wow! That's a question from a totally unfamiliar angle! All the pianos that have gone through my shop get a new redesigned soundboard, new bridges (new root, everything - because of string rescaling), new laminated bridge caps, etc., etc. So, as long as I have a new bridge root loose from the soundboard, it is an easy matter to simply notch the bridges before you glue/bond the bridge root to the soundboard. Indeed, if one were to want to notch a bridge of some very hard material, that would be a problem. But I suppose, that is a good application for a cap with thicker laminations - as I stated, not a whole lot harder to notch with a chisel. And regarding your comment "Since you're using a cap I suppose that you are not removing the bridge root from the piano." What do you mean by that? What does using a bridge cap have to do with using an original bridge root or a new bridge root?
