5 years ago I did some research on John Monteleone's one piece mandolin bridges that he built in the early and mid 70's. I found that like violins, he was striving for the bridge to be perpendicular with top at the inntonation point. Like a violin, it would seem while looking at it, that the bridge leaned towards the tailpiece. As I set bridges for customers, I take this same approach and I find that it loads the top well if the tailpiece angle is natural begining from the rear rim/tailblock area. Ken C
