I always examine the angle formed by the counterbearing bars and often find that some modification is necessary (as has been discussed) because the segment lengths are either too long or the angle not acute enough for the length. But on these particular pianos the angle seems adequate so sometimes I keep them.

He doesn't know the purpose either but chooses to keep them. I always assumed they were meant to prevent any sliding that might occur during stringing or shifting from torquing the screws down. I keep them if I'm keeping those front bars, which is becoming less of a practice these days anyway.

What is the function of that screen? Is it necessary to replace it when remounting those bars?
