Ok guys I finally had time to take some measurements on the CMM with different combinations of inserts. I also measured the distance to the centerline of the mount insert pockets. It was worse than I originally thought. All measurements are to the centerline of the chassis. Here's what I found:
Inner hinge pin angles with 0 inserts:
Left 2.73 degrees
Right 3.60 degrees
Inner hinge pin angles with 0 insert right side and .5 insert out on left side:
Left 3.22 degrees
Right 3.60 degrees
Inner hinge pin angles 0 insert left side .5 in on right side:
Left 2.73 degrees
Right 3.08 degrees
Inner hinge pin angles 0 insert right side 1 insert out left side:
Left 3.69
Right 3.60
Centerline of chassis to centerline of insert mount pockets no inserts:
Left .9004"
Right .9280"
Offset of pockets to centerline of chassis:
.0138" towards right side.
I measured my mount at .010" offset with calipers, but looks like the holes in the case are also offset about .004"
No bueno.
