CLT Grip
« on: October 28, 2008, 11:19:09 PM »
I have always used a t-grip with a span of 4 5/16 middle, and 4 3/8 ring, with 1/8 reverse on the thumb, and zero lateral pitch on the thumb.  Does anyone have a suggestion on what pitches to start with if I wanted to experiment with the CLT grip?

Thanks

I understand the theories, and quite frankly, I agree with the notion that all are t-grips, but for the sake of argument, I am just interested in trying something different.  I actually drill balls, and some customers have specifically asked for em to duplicate their "offset", so I do.  I am just more interested in the theories in the thumb lateral pitch, when doing this as opposed to current lateral pitches being used, or if they should be the same.

Even though I drill balls, I don't like to assume I know everything, so I keep myself open minded about other techniques and then make my own opinion about them.  I usually don't venture in this section of the forum that much, but I happened to speak to another driller recently who I came to respect, and just wanted to get some other feedback.

All grips are T-Grips. What the CLT amounts to is the finger pitches not being straight forward towards the thumb. For a right hander, the finger pitches are turned to the right while the thumb pitch is drilled the same as it always is.

Being trying to find Mo's claw grip, it is a variation that works better than a standard CLT. The claw creates easier grip pressure and more hand in the ball without trying, the less you do the better.

I searched some of the morich site with no luck finding it for you.

Barry, let me know if you find it. I'd be interested in looking at it and trying it on an old ball to start.

Thanks for the opinions.  Now for another question.

Couldn't we make the CLT line, line up more closely with the inital centerline by changing the angle of the oval in the bowlers thumb?  In a sense, isn't that what drillers who use this technique are doing?

There is no such thing as a CLT grip.  There is only one set of measurements that will describe a correct bowling ball grip in a sphere.  One can move the thumb to a tangent line off the middle finger but you still need to have a center line in the grip.  That's the standard for measuring the grip and pitches.  If you were to take a bowling ball with no label on it, you wouldn't be able to tell the difference between a CLT and a "normal" grip.  You can only lay out a certain spec in one way - CLT or otherwise.  The only thing that CLT is doing is altering the thumb pitch - more left lateral than "normal" for a right handed bowler.

Not true....The CLT Grip is altering the finger pitches, not the thumb pitch. The CLT Grip does exist. The thumb pitch is drilled the same as it always is for a T-Grip. The fingers are drilled in the same place as they are for a T-Grip also except the pitches are turned to the right for RH bowler. (left for a LH bowler) They are drilled off a different center line, thus the name "Center Line Transfer (CLT). The distance this line is from the middle of the thumb hole will vary from bowler to bowler depending on the size and how his hand is shaped.

here try this it is pretty comfortable.
SUGGESTIONS FOR MAPPING OFFSET DRILLING

1.  First draw the finger line with bridge & line for the first span.
2.  Split the intended hole size in half   (Sample drawing is 31/32 hole for finger inserts - actual size)
3.  Measure the first span from the center of the finger hole towards the thumb hole (Sample drawing is actual size of 4 3/4 span) and make mark.  This mark should be on the width of the offset you intended to drill.
4.  Draw a line from the finger line towards this mark for first span. Measure the width distance of your intended offset (Sample drawing is actual 3/4 inch offset)
5.  Draw a line from the offset mark towards the first span line to the bridge line. This is the thumb line.
6.  If you are using thumb slug or thumb insert subtract 1/8 or 3/16 from the span for drilling.  (Sample drawing is actual size 1 1/8 as if the thumb hole is the finishing size)
7.  As to drilling the thumb hole here is one major change from in-line (traditional) drilling.
Here is our recommendation
You set the ball for drilling the thumb hole on the thumb line.  The reason for this is the pitches you are putting for the thumb hole will be the true pitches for bowler’s comfort. You will find with longer spans that the reverse pitches do not get to the 1/2 to 3/4 inch area, 1/8 to 3/8 will be sufficient. Most bowlers will be happy with 1/8 to 3/8 reverse pitch. Right lateral pitches, for better feel with offset thumb.

8.  Drill thumb hole and finish to fit comfortably.
9.  Re-measure the first span from the center of the thumb hole to the center of the finger hole. Then measure & mark your second span to the center of the finger hole. (Sample drawing is actual size of second span 4 7/8)
10.  Finger holes are drilled on traditional center line for true pitches.

NOTE
To determine the width of the offset
Set the span lengths on the span gauge.  Loosen the screws on the thumb hole & move the thumb until you see the customers palm is nice & flat on the gauge. Then tighten the screws to set the gauge for the offset distance.  
Here are some guidelines to offsets:
Small slim hand  - offset 1/2 inch.
Small meaty hand  - offset 5/8 to 3/4 inch
Medium slim hand  - offset 3/4 inch
Medium meaty hand  - offset 3/4 to 7/8 inch
Large slim hand  - offset 3/4 to 7/8 inch
Large meaty hand  - offset 1 to 1 1/4 inch

This is the most convoluted BS I've ever encountered.
READ BT;s Book please. NO such thing as an offset thumb. This is just complicating what was simplified yeeeeeaaaars ago. Why are we re-inventing the wheel? Cuz Mo, Del Warren, Joe Slow-in-thinking say so. Just trying to make names for themselves, nothing more. Sheesh...…………………
BT's methods were proven & worked. Fit a ball to bowlers hand not what some 'new' guru 'thinks' it should be. WTFEver

This has been around since the 1940's.  Brunswick even had a patent on their "Brunswick Offset".  As each generation comes along, it gets pulled out and given a new name.

Brick Guy speaks with straight tongue.  The only thing I'll add is, it takes a bit of fussing around to get the right angle of the new centerlines if you try to fit each individual.  For many years I used a point  1/4" from side of thumbhole(Rt for RH and LFT for LH) to center of fingers and used same span on ring finger as the middle finger.   I made a lot of bowlers happy with that setup. I usually added of bit of "under" pitch on the fingers to make up for relaxing the grip.
