I found a hard copy of the analysis Oakley sent me. I couldn't figure out how to get the diagram posted so I'll try to explain the legend
A= Distance between Fret 1 and 2
B= Distance between Fret 1 and 3
C= Distance between Fret 1 and 4
D= Space between String 1 and 2
E= Space between String 1 and 3
F= Space between String 1 and 4
G= Angle of forward slant from Fret 1 to 3
DIMENSIONS FOR THE THREE GUITARS ARE AS FOLLOWS:
[All dimensions are in inches, as measured on my guitars with a ruler calibrated in 1/32 of an inch. Dimensions may vary slightly from guitar to guitar of even the same make. But this should give some idea of the degree of angle on the bar on the nonpedal guitars under consideration.
A=Frypan=1.1265;Rick=1.1719;Sierra=1.250
B=Frypan=2.2656;Rick=2.3125;Sierra=2.4676
C=Frypan=3.2813;Rick=3.3594;Sierra=3.5937
D=Frypan=0.3281;Rick=0.3646;Sierra=0.3385
E=Frypan=0.9843;Rick=1.0938;Sierra=1.0155
G=Frypan=66.5172;Rick=64.6861;Sierra= 67.6312 (degrees)
Consider a forward bar slant across strings 3 to 1, and from fret 1 to 3. The angle the bar would subtend in that movement is approximately as follows:
The arctan of G is B/E. For the Frypan: 66.5172 degrees; For the Rick: 64.6861 degrees; For the Sierra: 67.6312 degrees. To give some idea of how small the difference in these angles are, comparing the Sierra and Frypan consider the following:
The difference in the angle through which the bar pivots: 67.6312 degrees less 66.5172 degrees =1.1139 degrees difference with the Sierra moving the greater amount.
Or another way of evaluating just how much the tip of the bar on the Frypan would move by holding the pivot point on string 3 at fret one and allowing the hypotenuse of the triangle to be the radius of the arc one is swinging with the bar, the bar on the Frypan would have to move an additional 48 thousands of an inch, just slightly over 1/32th of an inch, and less than 1/16th of an inch. Pretty small
Interestingly, the Rick requires the lesser angle of the 3 guitars, with the Frypan second, and the Sierra a close third. Well, that's about all the damage I can do, Rick. The reverse slants should subtend the same angle from string three to string one if the slant is conducted on the same frets under consideration. So, the Sierra, with the long scale will require greater movement up and down the neck (but not a bunch as it is only about 1 3/4 inches longer from bridge to nut, and the string spacing is almost as wide apart as the 6 string Rickenbacker.

Thanks again Oakley
