Interesting assumption. it may well be true but why would you want to subject the intonation screw to this kind of bending stress regardless.True, but RR probably uses a beefed up high-tensile steel 4mm intonation screw (hopefully) instead of the typical 3mm. As long as the components are sufficiently strong and high quality, which i expect they are, and they look like they are, the 60 pound tension of a string is not large compared to the strength of the components.
Why put all the string tension on the intonation screw? There is no string tension on the intonation screw in a conventional design. It's a compromise that is needed in the RR design, but it seems to me that there are a lot of compromises we have to accept in this design. I still wonder if the stated advantages of this bridge are worth all those compromises. Perhaps they are.The maximum stress on the RR intonation screw will be string tension plus the force needed to overcome friction between saddle and baseplate. Despite the downforce this friction will not be huge due to having 2 large smooth flat surfaces sliding against each other.
I think it is possible the components are strong enough for this to not be a problem.
