Title: Change finger pitch = span change?
Post by: JS on February 27, 2007, 10:54:03 AM

Does a change in finger pitch also indicate a change in span?

I recently changed my finger pitches from 1/8 forward to 0.  No other changes were made.  After bowling and the next day I have some pain in my middle finger between my middle joint and the knuckle (on the back of the hand). I read Bill Taylors book on laying out a ball but it wasn't too specific on this.  Does the span have to change for this kind of pitch change?

I would not change spans for a 1/8 pitch change.  Probably would for a 3/8 change.  The finger hole's not too tight, is it?  --  JohnP

JohnP,

No, they're not tight.  I have "arthritis" bumps on my fingers and I open the finger inserts with a hand drill.  The fingers go in very easily.

I did switch from Turbo to Vise grips.  That wouldn't have an effect, would it?

Thanks....John

Not sure, but I wouldn't think so.  Was there any change in the lateral pitches?  --  JohnP

Both were ovals.  I checked the span and it is exactly on.  The laterals are supposed to be the same.  I will have them re-checked this Friday.  Thanks for the responses.

So who's drilling your balls now, John?

My laterals are the same: MF 3/8 left and RF 3/8 right.  These are the same laterals that I had with the 1/8 forward.

Jeff....pm sent.

John,

I agree with JohnP.

Could you just have had a tendonitis attack or an arthritis flare-up?
and the change is coincidental??

Jeff, I guess it's possible that it could be attributed to something else but this is the first time that I had pain in my middle finger.  When I spoke with my driller he just suggested that I go back to the 1/8 forward pitch in my fingers being that I had no problems before.  My fingers are very inflexible due to many, many years of bowling and I'm sure that 1/8 forward is not the right pitch for me.  Although I had no pain, I never felt the ball on my finger pads either; felt the ball on the side of my fingers.

I tried going from zero to 1/16 forward in my middle finger and used it yesterday but still had pain.  The Vise grips seem tackier than the Turbos I used in the past.  Is it possible that the tackiness has something to do with it?  I guess my next step will be to order some Turbos and try them in these balls.

I can see how a tackier grip could cause more stress on the finger joints.  Have you considered trying a ball without grips?  If your joints are very inflexible, you need a fair amount of reverse pitch.  Your finger pads should be in full contact with the front of the holes.  I personally use 3/8 rev on my MF and 5/8 rev on my RF, without grips.  --  JohnP
