Stephen asked: "What is the "official" rationale for splaying the strings within a trichord at the bridge? or is it one of those little bits of piano folklore that keeps propagating because it's assumed to be "necessary because we've always done it"? It's done even on straight-strung stringbands, as much as to the point of having all strings the same separation at the bridge, like you see on some over-strung pianos. What dire consequence might result from keeping strings parallel within a trichord? And have these consequences actually been confirmed experimentally or by supposition?" Stephen, The only reason that I've been able to come up with is to"spread" the hitch pins, so that they are not so close to each other, which might exaserbate a possible crack in the plate. After all, drilling holes in a casting does weaken it and if the hitch pins are all in a very symectrical fashion and close together, it could cause plate failure. (Or so I surmise.)
