If you want to use a pivot then try this:
Put the OB in the center of the table with the CB on the spot. Put your Bridge/hand 12.0” behind the CB.
Drop down with the center of the CB aimed at the right edge of the OB, shoot and mark where the OB touches the far rail. This is approx. 30 degree cut angle.
Drop down on the shot with the tip of the cue ½ of its diameter to the right side with the shaft aimed at the right edge of the OB. Pivot the center of the tip to the center of the CB, shoot and mark where the OB touches the far rail. This is less than a 30 degree cut angle
Drop down on the shot with the tip of the cue 1 diameter to the side with the shaft aimed at the right edge of the OB. Pivot the center of the tip to the center of the CB, shoot and mark where the OB touches the far rail. This is less than the cut angle above.
So if the shot at hand is less than 30 degrees, one can make an adjustment based on the results above.
Do the same exercise above except with the fractions of the tip to the left side of the CB aimed at the right edge of the OB pre-pivot. This will result in cut angles greater than 30 degrees.
Do the same exercise with the fractions of the tip aimed at the center of the OB for cut angles that are not quite a straight in shot.
Do the same exercises above with the tip 2 diameters to the side for even greater cut angles than those above. This is particularly useful for CTE aiming greater than 30 degrees where the final aim line is outside of the right and left edge of the OB where
one can’t use imagined points on the equator around the OB as a reference.
The rub is when the separation between the CB and OB are closer or farther apart but the principles are the same – just different tip fractions. Use smaller fractions for large separations and greater for small separations.
Now repeat the exercise using the quarters on the equator of the OB, then eighths etc..
Have fun or use ghost ball, DD, Cp2Cp or HAMB or…instead.:smile::thumbup:
