Hi Greg Aside from the point you are making about friction and bearing points... a C88 at 63 mm is going to just break period. I cant imagine any scale was designed this way, unless they had some kind of string material nobody knows about today... :) I can only imagine there must have been some error in placement of something that caused this condition when building the thing. We see regularly that all instruments...even those purported to having the most consistent assembly methods vary pretty significantly in this (and most other) regards. We have two (three years apart in production) new CF III's in town for example and C 88 varies by 3 mm on these two. I dont think given a reasonably executed scale will experience undue problems with string breakage to begin with... so I wouldn't consider bearing point friction an issue in this regard. Cheers RicB
