Center line transfer Questions
« on: June 08, 2003, 04:52:42 AM »
Ok, going back thru the posts for this and have a few questions.
I am going to try it.

1. Would you lay the ball out on the centerline of the thumb or the centerline of the fingers?
2. Should I make the thumbhole tight and oval it after completion of the drill?
3. Will the pitches of the fingers change?
4. Will the pitches on the thumb change?
5. Span stays the same right?
6. Has anyone tried a sarge easter drill with this?
7. If there is ANYTHING I missed please let me know...
8. Will there be a pap shift when I drill this??

Let me see if I can answer your questions....

1. Would you lay the ball out on the centerline of the thumb or the centerline of the fingers?
lay the ball out as normal, drill thumb first. then insert thumb into hole and lay your fingers out so they are where they would be according to your layout. Take a layout pencil and draw a line between your fingers. This becomes your new centerline to drill the fingers.

2. Should I make the thumbhole tight and oval it after completion of the drill?
make your normal thumbhole

3. Will the pitches of the fingers change?
use the same pitches you always did to drill the fingers. will they change? no. If you then measure the pitches off the original centerline, they will be different but don;t do anything different when drilling.

4. Will the pitches on the thumb change?
no

5. Span stays the same right?
yes

6. Has anyone tried a sarge easter drill with this?
no

7. If there is ANYTHING I missed please let me know...
not that I can think of

8. Will there be a pap shift when I drill this??
I did not see any

Good luck!!!!

So doug your telling me that I should lay the ball out on the thumb line..how would this make the layout readable. I am quite confused by the 1st question I asked...
anyone else. I am taking all this down in notes...

The reason for a CLT is to put the pads of your fingers in full contact the with the ball. This is accomplished by creating the new centerline between the middle and ring fingers as your hand sits in the thumbhole with your fingers stretched out in the area where the finger holes will be drilled.

Most of the time the new centerline ends up in line with the right edge of a RH bowlers thumb hole.

You can initially lay it out off the finger centerline if you want....drill fingers first and then kick the thumb out but it is much easier to do it the way I describe. You achieve the same results.

If I could understand what you are confused about, I could help you.

I am talking about the pin and cg position layout on the ball...
off the thumb line or the finger line....

Your center of grip won't change enough to make any difference so therefore the layout won't either.

With the balls I have done for myself the actual grip center has moved less than 1/4"

hi Doug,

May I ask if you've encountered any slowing down as to the exit of the thumb with this drill?

Been thinking of trying this for awhile, but am concerned that I my have to change pitches with the thumb again.

Regards

Even with the pdl file I am still foggy on this... Damn I must be thickheaded.

Ok the file says that you draw a line between your existing bridge how will this change the layout of the ball? How are the spans going to stay the same??
I am going to try this but I want everything to be figured out in my mind first....

ambi,

I oval my thumbhole a hair just like I always did so I have not had any problems with the thumb exit.

Buzzhead,

no the spans do not change, you are simply changing the reference point for the pitches to be drilled. This is why I said...you lay out the ball using the thumb centerline and then find your new centerline based on how your fingers lay in the ball, but you drill the holes in the sam spot as you originally were going to...you simply are rotating the ball to use the new centerline from the fingers as the reference line. The layout will not change.

Nice file there BT...good representation of how you drill a CLT.  I will agree that marking up a ball this was as apposed to an offset thumb is easier.  But aligning the drill bit to the cut lines is a little bit trickier for the driller depending on the press set-up.  Really just take a little bit of practice.  

The only thing that I did notice in the PDF file BT gave us is that the CLT measurement is taken differently than what I use.  By this I mean the CLT distance was taken at the center of the grip?  I extend the CLT line down past the thumb location and use the distance from the thumb hole to this line as my measurement.  Not that it matters for anyone that I drill for...but is there a standard for noting this measurement?  I would hate to see someone say that they have a 1/2" CLT and get it drilled wrong.

I noticed one thing on the document. the picture of him marking the line between the fingers.I don't think that is much of a an angle. depending on your span and hand, that angle could be much more. I know mine is.

as a personal observation. I think a CLt is ideal for a nice relaxed span. It allows maximun contact of the palm on the ball. this has to create stability and lesson the tension of twisting your thumb to face the finger pads.

Any crankers try this?

My guess is that strokers and tweeners would like this better. I would think power crankers with the cupped wrist and extreme hand action actually need the tension in the hand to help there releases. Now some slow crankers may favor a CLT because they can roll it off there hand better.

I am more of a tweener and I love the fit. MY .02c

Well I am a cranker and while I haven't utilized the CLT method on to many of my bowling balls I find that the relaxed grip is a definate improvement!  But that's me...

Unless I'm missing something, this just gives you a different center of grip reference line for positioning the ball in the jig, which I guess would alter your finger pitches slightly. Is that the idea?

The PDF document seem to take a regular T- grip ball then take the measurements to transfer over to CLT on a new ball.  i had a viper drilled up CLT and we drilled the thumb hole first, then i placed my hand in the ball, and he drew a line between my fingers, then traced it down to the right of the thumb hole (RH).  Then he laid out my fingers  using spans from a ball that I knew fit well.  The ball fits more relaxed.  I did experiment and I put 1/16" Forward pitch on the fingers because I figured the more relaxed grip would give me the sensation of falling out of the ball.  It works nice.
