I haven't done too many bridges, but I wonder if there is too much side 
bearing. To make sure there is just enough, but not too much, set the pins along 
the string line. In other words, before drilling the holes in the bridge, attach 
the new bridge to the piano, and put the strings on. Draw a line on either 
side of the string, and drill the holes, (with corresponding angles, of course) 
in between the lines. If the pins are put in the same line as the string, 
there will be enough offset for side bearing.
