It's a total load resulting from the angle difference between the speaking length, and the rear "duplex" segments, regardless of what the front and rear angles are relative to the bridge top. >Still, Frank Emerson earlier gave an example on > Baldwins with a significant mismatch between front and rear bearing where it > would be important to know.

As long as there is a total bearing angle in the range you allow, without a negative front or rear angle, it'll be fine. Ron N
