Thanks. I'd love to see the math just for my own edification. BTW Why would it matter if the front and back angles are symmetrical or not?

Assuming symmetrical front and back angles, etc. -Mark ================================================= Let's simplify a bit more. Take the scenario below and let's say there's a 15mm spread between the front and rear bridge pins. What would the reading need to be to indicate a total bearing (front plus rear) of 1 degree. I just need a baseline. I use this for checking bearing on a strung piano at tension. A couple mm difference in the bridge pin spacing isn't that critical for this operation.

I zero the three prongs on a level surface. I place the center plunger on top of the string in the center of the bridge. The two outer prongs are resting on either side of the bridge. The dial reads .018. Do I have 1 degree of overall bearing? And if it reads .036, I assume I have 2 degrees. Do I have that right?
