Title: Thumb pitch problem-help needed
Post by: 1fife on September 11, 2003, 04:02:43 PM
well i have a hang spot in my thumb. It was there last year, but not as bad as this year. I have been searching for the right thumb pitch for 2 years.

if my thumb hole was a clock
its rubbing at 11:30-10:00

i bevel alot, but that doesnt seem to do the trick
i have tried
3/16-3/8 reverse
and
1/8 under to 1/8 away

all seems bad
i realize everyone will say-go to less reverse, but why would that cause the ball to hang where it does.

i drill my own stuff-only ever seem to have problems with myself
span(cut to cut)
4 5/16 for ring finger and  4 3/16 for middle
im right handed
grips(both 3/4) turbo soft ovel 1/4 reverse on both and both pitch 5/16
thumb 63/64

last two balls drilled
3/8 reverse 1/8 away
5/16 reverse 1/8 under

both seemed equally bad

could a finger pitch help?

WELL?

1Fife,

I have trouble giving advice to someone with your profile.

But what should be your lateral pitch?  Coke Bottle test?

Also on bevel have you seen the tips Mo Pinel gave me on the drilling section titled "What Mo Pinel taught me about bevel"  I thought what he showed me was great.

I rarely hang (well except for last night???)

REgards,

Luckylefty
PS based on what you are saying it is side bevel but front is propably fine!
Also your reverse pitch is in the right area too.  Maybe a slight bit forward is perfect but not if your thumb is stiff or you hang.

coke bottle
between first finger and middle, but closer to first

which points to 1/8 away

and i bevel just like mo says

ring finger only in hole and release themb
then middle finger only and release thumb


AND WHATS WRONG WITH MY PROFILE  

i talked to lots friends and they give advice. seems like locals anll think the same way-maybe a view outside of the window would work. Or maybe someone has had sme problem and came to a solution

Nothing the matter with profile, just thinking of how I bowled last night in league versus your impressive average and profile!  (Should I be giving advice!?)

It just sounds like going 0 lateral might work also, like maybe you have a little too much reverse.  And it sounds if you are hanging in the 10 to 11:30 area like it is a middle finger test/side bevel area.

Regards,

Luckylefty

You are probably hanging worse this year because of the warm weather causing you thumb to swell or be tacky.  The location of the hang implies to me that
you will need to make the hole larger in that area.  3/8 rev and 1/8 away should make you fly out of the thumb if the hole size is correct.  If so, then you are probably squeezing another cause of hanging and thumb swelling. We have the same span and rev pitches on fingers, but I use 1/8 away and 1/8 rev for my thumb.  I have even used 0 rev and 1/8 away.  It is very important to have a relaxed grip and reducing reverse helps with that.

the mo finger test doesnt feel bad when im at home-just seems to get worst as the night go one(or the lights turn on)  

thumb swelling-it does and i have to take about 2 pieces out as the night goes on(always have had to)

squeezing-probably have always have, but this year i thoguht that may have been the major problem and have relaxed my thumb-still happens

i have a huge bevel in the area of problem and thnumb is not close to round anymore. oblong (sp?) in shape


should i try more under or more away than 1/8?

hate to say it-more reverse

i have tried (experimented) with 1/8 reverse only and 0 lat and that didnt seem to be better.

since i have went either way from 1/8-3/8 reverse and 1/8 lat both ways, im thinking maybe i need to try more?

i have all the equipment, so im game to try anything(its not like plug material cost much)

this sucks, my game is suffering big time
i have big expectations and small performance

This is just some thoughts,Is the span correct?You said you have had problems hanging before.I think that if you tried 0 lateral that would take care of the 10.30 hang.
Do you oval the hole or have tri ovals.if so is the angle right.should you be using ovals.

I have seen people who have gained wieght and develope hanging problem.Did you?

maybe you body is changing and thus you may need a new fitting.Try and stick you thumb in the thumb hole and see where your fingers lay across the finger holes.Is the first crease even or past the inside part of the grips.Tension in the hand can cause you to hang,have you tried a CLT drilling"realy makes the hand more relaxed" These are just some ideas from out side of the window.

checked span again yesturday

center of finger grip in directly between the crease in finger

i have tried shortening span by as much as 1/8 inch and lengthening it by 1/8 to no help

weight, well some, but not much

maybe i should drop ring a little or lengthen the middle a little and give it a try.

Well, one more thought.

Next time you go and practice, bring a bevel knife and bevel as thumb swells?!

Just a thought, if it is good on bench but not at alleys!

1fife,

1. Where are you hanging on the thumb..?

2. Where are you callous's..?

3. After putting your fingers in the ball first, as you drop your thumb in the hole, does the back of your knuckle hit against the back of the hole..?

4. Do you also feel the top front edge of the hole, pinching at the inside base of your thumb..?

5. Can you feel the sides of your thumb touching the sides of the thumb hole, more than the front and back of the thumb, when your thumb is inside the hole..?

After answering these questions, I will be able to suggest a recommendation for you. =:^D

Which thumb slug are you using?  There are vynl and urethane, the urethane makes for a quicker, smoother release.

1fife -- You did not tell us if you use a thumb insert.  The resin balls can "bleed" inside the thumbhole, causing stickiness, especially in combination with a damp, swelling thumb.  I recommend that my customers use either an insert or a slug on these balls. -- JohnP
Title: Re: Thumb pitch problem-help needed
Post by: 1fife on September 12, 2003, 12:39:00 PM
t god

ill think about them and answer in a bit


slugs-
well some balls have them and some not, to ne honest i have never seen much difference.
I plug and redrill thumbs all the time, some have slugs-some not

i sell all balls i dont like and it easier to not have slugs-easier to slug it and sell for new customer(ball looks new-no plug)

so i have slug and not, but all balls are doing the same thing-hanging

1fife,

SIDE NOTE_MY THUMB IS NOT VERY FLEXILBE-short stubby little thing(yah i heard all the jokes already)

1. Where are you hanging on the thumb..? when im releasing the ball on the front(closest to fingers) left

2. Where are you callous's..? back left and right in front-none really bad. My thumb looks good, not like some of the ugly bowlers thumbs ive seen

3. After putting your fingers in the ball first, as you drop your thumb in the hole, does the back of your knuckle hit against the back of the hole..? no front hits(in 10:30-11 area), then i can feel the back(in the7:00) area-

4. Do you also feel the top front edge of the hole, pinching at the inside base of your thumb..? yes

5. Can you feel the sides of your thumb touching the sides of the thumb hole, more than the front and back of the thumb, when your thumb is inside the hole..? yes, but left more than right

Post by: T-GOD on September 12, 2003, 09:57:09 PM
1fife, here are some suggestions..

1. Because you're hitting on the front left of the thumbhole, you will usually need more right pitch. You can also try more reverse pitch, i.e. 3/4"

2. The span is slightly too long, because you feel the front edge of the hole as you're putting your thumb in the ball.

3. Because your thumb is short, stubby and not very flexible, I would think that your ring finger should be shorter. Place your thumb in the ball, then lay your fingers over the holes. Then measure the distance from the front of the hole, to the crease of your finger. You want the distance to be the same for both fingers. The crease should almost be in the center of the hole, but probably just before.

Let me know what you come up with for the distance of the crease to the front of the hole for both fingers.

4. You will need more/the proper bevel. Bevel is the most important thing concernig a thumbhole. Try beveling down deeper inside the hole, and taper it out towards the top like a funnel. This will allow your thumb to go in deeper, but also come out without hanging.

Keep beveling the ball, wherever you're hanging, until you don't hang anymore..!! Then, tape up the hole on the front and backside, until you're able to hang on to the ball without squeezing it too much, while also being able to release the ball whenever you want to without hanging.

Do whatever you have to do to get rid of the hang, as far as reverse pitch and bevel goes. You say you're using a lot of bevel, but it probably is beveled properly.

So, my recommendation is to use 3/4 reverse, 0 lateral pitch. Let's start out with alot of reverse, so you can clear the ball. It's better to exaggerate to the extremes, so you can feel the difference and get the desired effect. Then, you can cut back on it later if you want.

Also, I'm guessing that we'll have to shorten your ring finger to 4 3/16. This should get you out of the ball along with some bevel. After you're clearing the ball cleanly, you can start to reduce the reverse pitch and bevel to where you start to hang again. Then, you'll know where you should be.

There's nothing wrong with using 3/4" reverse pitch, it's only a number and may be what you need, depending on your thumb and how you want to release the ball. =:^D

T-GOD these are good points and should help him out alot,this is what I was getting at that maybe his span was to long but never got a chance to answer.I also thought he may need a little oval if the sides of his thumb were hitting.But it could give him trouble if the angle of the oval is not correct.I think he should try what you suggested first,then go from there.

Ok, the more you bevel your thumb, possibly the more you will squeeze it later when it gets cold.  It appears to me that you need a oval thumb.  Go back to you original pitches and oval the thumb.  No ones thumb is perfectly round.  Please remember, more bevel means you have to squeeze the ball.  It will change your release point to some degree.  Also, if more bevel is working, then your span is too long.  All bevel does is place your thumb into the ball at an angle and sometimes if too much will cause you to knuckle the ball.  Go to a good pro shop that has a Mill/Drill and let him oval your thumb.  Good Luck

Post by: T-GOD on September 13, 2003, 11:08:20 AM
Stan, as long as you keep the thumb snug with tape, you will not have to squeeze the ball. Actually, you should have to grip the ball slightly to hang on to the ball. If not, the ball is controlling you, and you won't be able to release it when YOU want. The key is to minimize the gripping as much as possible, but still be able to exit the thumb freely.

And, with the proper bevel, you will be able to place your thumb/hand in the ball at different angles, which changes your grip and release/turn. Being able to change the way you hold the ball or having your hand in the ball at different angles, and allowing for different releases, lets you throw the ball with different rotations and will aid in "pocket carry' instead of having to switch balls or move on the lane.

If you don't use bevel and your thumb is snug, i.e. "a perfect fit", you can only come out of the thumb one way and your timing must be perfect, or you'll hang up. =:^D

Post by: Stan on September 13, 2003, 11:48:01 AM
T-God I am not saying not to bevel the thumb hole, but just make it enough to be comfortable.  I agree that tape has got be be used in the thumb in order to maintain a good feel.  Too much bevel is not good for anyone and I srtongly disagree that it is used to change the roll on your ball.  Yes you will release the ball differently with a lot of bevel but with too much tape, you will not obtain a smooth release.  It sounds like you are a avocate for a lot of reverse with even a lot of right lateral (right handed) and just use a lot of tape to keep the ball on your hand.  This may work for you, but when it comes to forward or reverse thumb pitch, it is based on the bowlers physical makeup.  Lateral pitches can be used to drill for performamce.  The more right lateral (right handed)the easier it is to turn or spin the ball.  As I said, most people need an oval thumb in order to get a good snug fit (with tape but not too much).  Review the IBSIA guide for fitting.  I know the current guide is outdated, but there are still some basic guidelines that can be followed.

You fit the ball based on the bowlers makeup, then you fine tune with lateral for performance.

This was intended to give 1fife some insight to his problems,We offer ideas for him to try.I am a fan of the ovals exspecialy the tri ovals"milled".the bevel issue is touchy some say bevel till you can get out of it,and most of the time after you bevel it you have to stick a wad of tape in it to hold on.We all have good points and ideas to try but I still think his span is to long and he needs an oval.He could mill it out him self if he marks were it is hitting his thumb and sets his pitches.This will give him the right pitches "no funnel"And some where to start.

The unfortunate thing in all this is pitch is all about experimenting, i used to use 1/4 under and 3/8 reverse, always had to oversize the hole and didn't know it until i looked at my thumb at the end of the night. I now use 0 and 1/16 forward, much more comfortable for me. As most have said, tape is a necessity, or Magic Carpet, talk to my buddy Ron Clifton if you wanna try that, aka magic carpet on this site. Just keep trying new stuff, but remember, you want a snug fit that you can release without grabbing the ball, once you find that write it down and remember it.

Finger pitches can be critical to the release of the ball, depending on the flexibility of the finger joint.  If the joint (of either or both fingers) is stiff, it has the same effect as lengthening the grip.  I've put my customers into finger pitches as high as 3/4" reverse, with the only effect being that they can release the ball properly and their finger no longer hurts.  It does not seem to reduce the amount of lift on the ball.  But if all else works, do as T-GOD said and keep increasing the amount of reverse thumb pitch until the hanging stops.  --  JohnP

Yes,

I forget his screen name but Bowl Better Now was also commenting on coordinating finger pitches with Thumb pitches.

I wish he would elaborate more on this.
