I have been playing with this layout for one of my customers. Here is the info I obtained.
For a CLT, place thumb in ball w/ the fingers resting across finger holes. Make sure that the arm is straight and the elbow is locked. Draw the CLT line from the center point of the bridge down between the fingers. Extend the line from the ball bridge center line down to the CLT line, to past the thumb hole using a Pro Sect. Draw a line from the Bridge center (between finger holes) through the center of thumb hole for the grip line. Measure distance from the finger to thumb and mark the center of grip.
PLace fingers in finger hole and place thumb halfway in thumb hole and mark both sides of thumb hole at half of thumb hole diameter. Use the lines on the back of the customers thumb for reference points.
To determine finger degrees and thumb offset, place zero on the pro sect scale on the bridge center point. align the back of the pro sect with the center line of grip. Read where the Clt line intersects on the degree scale on the Pro Sect to determine the degrees for fingers. Example 13*
Measure from grip center line at top of the thumb hole to the CLT degree line to determine the offset number. example 1/2 @ 13*
To determine the oval degree for the thumb, place pro sect scale zero in center of thumb hole, on the grip center line. Use the thumb lines to align the pro sect with scale on the left side of ball. Read where thumb line intersects with degree scale for thumb oval degree.
To use the CLT line for positioning inserts, place Pro Sect on CLT line with Zero on CLT line and at 90* angle to CLT line. Draw a reference line. Turn grips to align for customer trial.
