Contact Point + Bridge Shift Aiming System

Colin Colenso said:
Hi Rick,
The ball at 2.25 inches is 1.125 inches from center to edge, or about 28mm or a bit over 2 tips. The contact point for a half ball hit is half that, hence approx 14mm or nearly 1 tip.

Partly responding to Pidge here too. It is hard work to do this, as it was hard to do arithmetic tables in our early days, as it takes time to learn CTE etc.

One would need to learn to do the math in a couple of seconds prior to each shot to work out the pivot shift required, then align to contact point and then bridge shift.

Of course it won't suit all, but it can be a an objective way to put a player in the ball park if they become au fait with the measurement estimations and the quick division, which will require more effort when trying to be more accurate instead of rounding off.

Cheers,
Colin

Hi Colin,

Got it, that's what I thought.

I'll give it a try probably later in the week.

Later,
Rick

I don't understand. Does anyone have time to put it in a picture?
thanks!

(shooting left to right, with the OB going diagonally to downward-rightward)

the gist is in how to go from first, sighting with the cue on the line from the upperLH black dot to the lowerRH red dot (this line is NOT in the picture), ...

...to then getting the cue onto the line between the upperLH and upperRH black dots (indicated with the solid black line)

How about one tries for the 90 degree cut where one has to contact say the 3:00 CP edge on the OB with the 9:00 CP edge of the CB and with a constant 12" bridge behind the CB?

Locate the center of the GB (can use the arrow) and aim the center of the CB at it with the cue. Then pivot the tip of the shaft from the bridge until it is pointing at the CP or 3:00 on the OB. Then memorize how many tips are needed to be offset then pivot back to the GB to check and shoot.

Do this for every diamond separation between the CB and OB.

Repeat this for every cut angle and memorize the results for use later...like a multiplication table.

Be well
