Title: CGs/MB back towards the grip center. Whatever happened to those old label drill
Post by: LuckyLefty on September 02, 2012, 08:21:26 PM
We all know, cg or mass bias out usually creates more midlane.  CG or MB stacked creates less.  Cg back towards thegrip center(correction) or  MB or under the thumb or in the track seems to create what used to be called lope or wait before the ball made it's move!

What is the relavance of this not as often used drilling in today's game?  Especially for bowlers with plenty of side roll.  Lope is a part of their roll already.

I am bowling in a center where drillings that create midlane just force me very deep.  I have 60 to 70 degree side roll, can cg back towards the grip center or MB under the Thumb work for me.  Traditionally they haven't but I think that certain conditions make it more likely it would work for me. 

Drilling gurus?

Cg nomaddah. Right.

Mass bias is totally different.

"Cg back towards the MB or under the thumb seems to create what used to be called lope or wait before the ball made it's move!"

That makes no sense to me but I'm sure it will to someone.

Not sure about cg under the thumb as you listed but the cg location is really only relative in terms of static weight and if your going to need a weight hole to make the ball USBC legal. Or if your wanting to put a weight hole in a specific location to effect the balls reaction. The cg isn't always inline with the pin and mb, so where the cg ends up in the drill pattern isn't relative unless for static weight purposes as stated.

Now in terms of putting the mb near, or below the thumb it just delays the reaction of the ball more. It doesn't kill the reaction by any means. You can even move the mb to the side of the ball you track on for delaying and taming the balls reaction.

I have a Clutch drilled 90x4x65, and its awesome on the ths. Strong pin, with a smooth MB. Have to watch the surface on it, because oob, it was too much on the ths, but at 1000 with polish, it was not enough. I think I have to keep it at about 2000 with no polish.

I have had great success with balls with the MB in the track. Predator, Vortex Afterburner, Tomahawk, Stinger, Heat remake, and probably some more that I can't remember at the moment. All different pin lengths and angles to the val. For me, it allows me to stand closer to the friction, and not have it go crazygonuts off the dry.

For Impending Doom.

Did you see much different reaction when the pin was next to ring finger or up with all of those label drilled balls?

For the other posters...

I have found lately at least one company that is totally confused about CG when giving their drilling Instructions...  900 Global.  In their comments on their drillsheets which I picked up from a bounty drill sheet(included symmetric also).  They mention the CG position as earliest(3 inches to PAP), early(4 inches to PAP) and latest(5 inches from the PAP).

What do they know!?

Longer pin to pap on asym to make the ball roll forward sooner. Longer pin to pap on asym wont reduce flare..

I looked through the drill sheet for the Bounty shown above and it never gives any specific measurements for the CG, it does give specific measurements for the PIN to PAP along with a general area the CG should end up in.

All the pin placement did was dictate the amount of flare. I've gone anywhere from 1 inch pin to pap (Track Money) to 2 inch pin to pap (Predator, Blue Heat, TNT) to 3-3/8 pin to pap (Afterburner, Tomahawk) to 4 inch pin to pap (Threat) to 5 inch pin to pap (Heat remake, old Tidal Wave) I usually used holes on the shorter pin to pap, to make them even smoother. My Threat, drilled 60x4x20 was too sideways off the dry without a hole. I took it to .5 negative, and it became a lot more controllable. I didn't normally use big holes, but smaller deeper holes on my pap.

Obviously, the 5 inch pin to pap had more jump to it at the back, but it was still super smooth. It's my belief that you should have a least one ball drilled to have tight flare, so you can feed it to the dry without it going nuts. The ball motion of the new AMF Cobra is similar to that kind of look.

pin to PAP dictate overall amount of flare potential....after taking that into consideration, you have take the strength of the mass bias into the equation + the amount of flare already created and use the mass bias as more of a down lane adjuster or modifier. IMHO a mass bias is comparable to a weight hole in a symmetrical core ball....

Yes they have posted videos showing the cg location and the effects on the ball being thrown by a throw bot. That has nothing to do with what I've read and tried to translate from your post. I will just assume that your sheet for the Bounty has the listed information that Global doesn't list on the sheet from their website. As mentioned already, the cg location and the MB location are very important in the layout of the ball and its reaction. The end results of the cg are important because that weight has to be accounted for when making the ball legal for static weight purposes and also for adding weight holes to specific locations to change the dynamics of the core for a desired reaction. Still it would appear no current drill sheets list anything about the CG being a certain distance from the bowlers PAP. Most give general areas the CG should end up on a first quality ball.

When reading your original post the comments/assumptions you make I've not read else where. If you take what is written below and subtract the CG then it would be what is generally seen reaction wise by most bowlers.

"We all know, cg or mass bias out usually creates more midlane.  CG or MB stacked creates less.  Cg back towards the MB or under the thumb seems to create what used to be called lope or wait before the ball made it's move!"

"....can cg back towards the grip center or MB under the Thumb work for me."

Post by: LuckyLefty on September 04, 2012, 07:54:40 PM
Two of the settings from these older type of drill sheets, That discuss cg position on symmetrical balls, could end up with no weighthole possibly(depending on starting top weight).  Still the drill sheets imply different reactions with the same pin position?
I believe it is possible/probable your thoughts?

I do appreciate where this discussion has gone and the last several posts I view as well thought out, helpful and introspective.  Thank you.

Post by: kidlost2000 on September 04, 2012, 08:16:30 PM
Back in the day the thoughts were lots of finger weight caused the ball to have more length and lots of thumb weight cause the ball to roll sooner. Since USBC limits you to less then an once either way I'm not sure it is really true.  That is to say, take two identical balls with two identical layouts. One having one once finger weight and one having one once thumb weight and using a machine to throw the ball and see if there is any difference.

For me, my only concern when drilling a symmetric ball and the location of the cg is if I'm wanting to have the option to add a weight hole in a specific area to increase the dynamics of the ball.(internal differential)  Between the large hole drilled for the thumb and the weight hole you are taking out very large pieces of the ball and some(in most cases) parts of the balls core.

Generally I'm looking to have a weight hole at least 3.5" deep for that reason.

Kidlost2000,

For your consideration
From Ebonite's website today.
http://ebonite.com/resources/drill_detail/symmetric_core_drilling_instructions/

Note in many of the instructions they detail who these drillings are for.  Note all of cg back towards the grip center they note minimal axis rotation or a hooking track.

Note all of the maximum axis rotation drillings have the cg out and weightholes on the Val either near the PAP or down(for more rev up), like the Revs Leverage(one of this lefties favorite drillings!)

The point being that Max axis rotation bowlers(like me) often create lope and the cg out combined with the weighthole, give me midlane.  While a hooking track can add the element my ball needs to create midlane with my side release that being friction!  This friction in special circumstances can make the label drilling appropriate for a maximum axis rotation bowler.

This above ebonite drill sheet in my mind confirms the 900 global sheet I referred to above.  CG out, stacked, or towards grip center give different rolls and looks on the lane according to 900 Global and appears to being confirmed by the Ebonite sheets   The Mass Bias orientation(or angle) in my opinion appears to be a multiplying factor where the ball reaction becomes more magnified for every orientation.

Post by: kidlost2000 on September 05, 2012, 02:19:14 AM
In all of the layouts they give no exact CG to PAP placements. They give areas between the center grip line and out towards the VAL to move the CG so you can add a weight hole for a desired reaction. It is the weight hole not the cg location that cause the desired reactions.

In every layout you can leave the cg on your center grip line and place the weight hole where listed. You will not be able to drill as big of a weight hole as deep as preferred to effect the bowling balls internal diff. As mentioned before, its the weight hole not the CG that makes the difference. Now the CG is relevant to help drill the weight hole in the desired location and size to make it worth while.

Post by: LuckyLefty on September 05, 2012, 06:51:53 AM
My point is that in the 900 global sheet 2 of the cg positions 4 and 5 inches can be drilled with no weighthole and the drill sheet indicates that one can expect different reactions.

Possible?  My tests say yes..

Post by: kidlost2000 on September 05, 2012, 07:51:10 AM
Your point varies and I can only go off of what your reading from a drill sheet I can't see. Your point about the Ebonite article isn't correct because what your saying they state in the article about the specific CG to PAP distances isn't true. They give suggested areas to locate the cg to add a weight hole to a specific area and then change the reaction of the ball. None have the pin in the same location and only move the CG with no weight hole to change the balls reaction.

Now I can only assume that what your reading in the Bounty drill sheet that is different from the one Global post on their website is true.

So on the Bounty drill sheet the pin to PAP is identical and only the cg is moved 1" and is suppose to have different reactions with the cg being at either 4" or a different reaction at 5" ?

The reason I find that hard to believe is because I don't have the mentioned drill sheet and because there is no way to determine the exact top weight of the ball to be specific when making that suggestion.

Example being,

One ball has a 3" pin and 2 ozs of topweight
one ball has a 3" pin and 4 ozs of topweight

Both balls when drilled identical and the cg is say 4" from your pap will have two very different side weights at that time prior to adding a weight hole.

Lets say you have the same two above bowling balls and both have the exact same layouts and the lighter topweight ball has the CG 4" from the pap and the heavier topweight ball has the CG 5" from your pap, because of the difference in top weight and location, they can have the exact same side weight on the ball with the exact same pin to pap location and two different CG to PAP locations. Are you saying the will react different because the CGs are different distances from the PAP even though the side weight will be the same?

Shifting the CG and leaving the top of the core/pin in the exact same location, doesn't move/shift the core on a symmetric ball. It is only shifting excess weight that can allow for larger weight holes, which then change the core shape and effect the balls reaction.

When you watch this vid you can see two balls drilled the same with two different cg locations and two very different side weights. You also see after that demonstration the inner core of the balls and what happens to the core as the cg is moved around the cores axis/Pin.

Lucky,

I think what you might be seeing is the "CG Zone" or some such thing. So if you don't have a ball with a big cg out of line with the mb, then the cg will be in this area. I guess 900 needed to verse people that can't understand mass bias? I don't know.

But take a look at this video.
http://youtu.be/UKLrdm6PtK8 (http://youtu.be/UKLrdm6PtK8)

You look at Tony's layout, it has the cg almost in his track, but the MB right of the centerline. Out of line CG doesn't mean much there.

I've thought a bit about this post and done a little work on a couple of balls(symmetric).

I was wondering if anyone knew back with the Throwbot testing referenced above,,
What is the axis rotation that the throwbot was using in the video posted by Impending Doom?

To me it all depends where your PSA winds up whether it's symmetrical cores or asymmetrical cores.  You use x holes on the gradient line to tweak desired ball reaction.  The issue being most pro shops do not have a Determinator so where the PSA winds up is up for question.  Note on the RG Shout that I am posting where the PSA is with no x hole and where the CG is and most would think the PSA would be in the thumb hole but it is not.  The actual drilling angle PAP to pin to PSA on this ball is 105*x 4.25"x 65*.  Ball is a solid nice length because of it's 1500 polished OOB and heavy arc on backend without a lot of over reaction.  My PAP is 5" over and 0.

I have made a couple of mistakes in my posts in this thread that may have gotten the discussion off track.

Mistake in #1 is that in that the original post I note the cg back towards the MB.  I meant back towards the GRIP Center for a symmetric ball or with the MB of an Assymetric ball under the thumb or back on the track.  Now corrected.

Mistake #2 is I referenced Impending Doom's reference to a video when I meant to reference Kldlost posting of the Brunswick video showing different CGs and throwbot throwing.

So given that here are my questions and comments so far and continuing.

1.  Does anyone know what axis rotation throwbot was set at to do the above different cg position videos?

2.  Scott above with the lines on his ball is illustrating basically the drilling I am talking about.  What used to be called 1:30(imagine the cg right on the grip center or very close.)  This on a symmetrical ball.  Or a this video drilling #4.
http://www.youtube.com/watch?v=iR3eKsm8LKY.

Now again I am a 60 or 70 degree axis rotation bowler and have done some testing of these different positions on my oiled to 35 foot shot, that supposedly is a 40 foot shot!  Yeah right!

LL--I would say that because you have a reasonable amount of axis rotation you struggle from the left side in that you maybe the only one on that side of the lane and get very little head break down as well as carry down.  Hence your side of the lane can be either a boon if you are a lower axis rotation player or a bane when you are higher.

I'd say you need to learn to lessen your axis rotation to calm the ball down off the spot.  I assume you are speaking more of house type conditions that have less side to side amount of blend and have a lot of friction to the outside.  Use a forward roll type of release to calm the ball down off the spot and maintain speed.

What I have learned in these situations (see my stats in profile) is that I use weaker balls like the Shout with weaker layouts like the one above or 1:30 drills as you suggest on the fresh house type condition as they break down I can move to something stronger.  1:30 layouts for me are good from the outside but not as good on carry from the inside.  With the Shout above I generally use a line of something like slide 23 with12 at arrows to 7-8 at break point and early on try to cut down on axis rotation with more forward roll.  As I move in and play increases I go to more axis rotation/side roll or a stronger ball (QZ-1 Red/Frantic pin up) if my carry suffers.  I can use the Shout OOB 1500 polished without the over reaction because of layout and 2.57 .022.  I am also bowling house shots on 1st Gen. Bruns Anvilane and have that for me with the 16 yr. old Anvilane though the surface is very hard the panels are very worn and polished equipment is a must anything with some surface tends to bleed energy quickly and hits poorly.  Low Rg balls for me on this condition and lane surface also tend to bleed energy.   

My reality is that most decent players with a decent hand and medium speed can use any lower cost entry level ball like a RG Shout or Motiv Ascent Solid and do well with them and save money on ball cost.  Generally most bowlers are using medium to high end pieces when they do not need to on house shots.  Only folks that need high end equipment on house shots are the high speed rev challenged bowler.

So with cg placement meaning little. You could ultimately drill a ball upside down with the cg above the fingers as long as static weights were legal, you would get the same.reaction as if the cg was rotated 180 degrees from that?

Yes, for symmetrics and depending on the weight hole. Pin placement is the key for symmetrics.

I am adding a link here that Scott33 sent me.

http://www.blueprintbowling.com/Blog/Posts/blueprint-testing-by-earl-and-supercats.aspx

This link does speak to the subject of different drillings but it does speak to the subject of how much a 60 to 70 degree axis rotation player adds to ball movement!!
Also the concept of effective rev rate based on axis tilt is interesting also.

The above concept of how much more movement one gets with a lot of side roll versus a small amount of side roll is quite dramatic.  Thsi is why I ask my question about throwbot and it's axis rotation for the cgnomadeh test referenced above.

I have recently done a bit of testing with some drillings that are symmetrics to verify some of my ideas.

Please anyone involved in the Brunswick tests above...axis rotation used?

so what happens with a pin in ball or a 1in pin and cg distance?? i have a total nv with that and was wondering if cg placement has any effect on the ball other than being legal? or if i can put cg anywhere and just use the mass bias for ballreaction??
Title: Re: CGs/MB back towards the grip center. Whatever happened to those old label drill
Post by: kidlost2000 on September 28, 2012, 10:26:56 PM
The EBI info does show some interesting things. Still the cg is merely weight displaced in the ball to keep it legal when drilling. If your going to test the theory yourself because you believe your axis tilt will make the ball move more if the cg is on the center grip line or towards the positive side of the ball it is simple to do.

Buy and drill two of the same symmetric bowling balls. Put the pin in the exact same location and then have one with the cg in and one with it out. Then go and start bowling. See if your results vary.

Post by: Rightycomplex on September 29, 2012, 06:49:17 AM
Stickz,

With a pin in ball i would recommend that pin and cg in the palm to provide normally depths of drilling or mark the PSA 6.75" from the pin, put the PSA beside the thumb and keep the pin about a half inch from the ring and bury the fingers while drilling and that way there's a possibility of adding a flare increasing hole later. But, same rules apply. It limits what you can do to a ball without doing something stupid like pin up and having to bury the fingers add/or P1, you can do it but its just easier to do the two above layouts. When i layout a ball, im trying to optimize the ball to their stats. If i know their stats arent going to match up with a pin in then i drill another pin distanced ball.
As far as the total nv goes, will have the same affect as above. CG on any ball will only have an affect on statics and weight hole placement. When you move too much of the weight away from 1 quadrant you will be require to have a weight hole.

Lefty,

Whats up man? Lol! I think your reading too much into the layout of symmetrics. If your axis rotation is affecting the ball that much then you need to weight the factors that are causing the reaction. Obviously the lanes and dry the whole way around so the ball of choice will be a low diff low end ball. If your getting around the ball to much, then drill the ball with more right lateral pitches (add an 1/8-1/4") to sit the ball more square in the palm so you come more up the back. And being left handed you dont really need the skid flip so i would lean more towards a solid low end like a manic if you wanted more hook or karma urethane if you wanted less. Placement of the CG will only matter to statics and weight hole placement. The ball is going to do what it is designed to do off of the bowlers stats. Pin placement will affect flare.
Now, if you layout 2 identical symms with the pin in the same spot and the cg in 2 different places, barring a flare increasing/decreasing weight hole, the balls will do the exact same thing give or take a board. If you do the opposite, putting the cg in the same place and changing the pin distance then you'll see a major difference in where and how much the ball reacts.

That's what I think too....I still say it's a technique issue rather than put a lot of effort and money into equipment fixes...I'd fix the axis rotation issue first. 

My guess is that the ball "fit" is an issue and only allows one type of release rather than multiple?  I have seen this time and again.  Fit only allows one way to get out of ball and maybe loose thumb so the use of death grip hang up and muscled arm swing.  Maybe yes maybe not but I tend to think it's more than than keep buying weak equipment.....though I shouldn't point fingers.   ;)

Here is a link that was just posted yesterday in regarding positioning of the weight hole on symms and how they affect differential and flare. Great work by Triplicate to show how all five positions (one not having a hole affects these properties. Lefty, I think this will do you more good than trying to figure out how to position the cg on symms.

Some wonderful points above.  Funny and I appreciate the comments both Scott33 and RightyComplex.  Funny in that just yesterday I rotated pitches more right!

I liked the results.  I again note on this shot unless lofting over 6 feet over the foul line with good speed I haven't seen hardly a bowler over 30 degrees of axis rotation have any good results, but at 20 degrees from fluffers to revvers it likes fish in a barrel.

I will tell you I bowled with one of the best bowlers in the house the other day, 230 average and 30 degrees axis rotation.  He doesn't know what he is doing....pin about 3 3/4 and up cg next to the grip center...House drilling, everyone that tries it seems to be dramatically better than those with Mass Bias or CGs out.

I can fight um...but i have to say I've joined em!  A drilling that has very seldom worked for me....DRAMTATIC difference in pocket ownership for me!

PS I think the changes recommended for my game above, will be very beneficial for me!  I do appreciate it the learning process.

I'll add even though for me I can lessen axis rotation I still maintain my tilt 17*.  The tilt part of the equation for me is what gives me better carry and ball match up, ball surface and lane surface/lane condition.  Being a lefty you see way less head blow up and head oil depletion and less carry down if anyone is using urethane/poly.  On the right side it is much more dramatic.

Well Lefty,

With 30 AR, they are getting the ball to roll heavier in the backend. You're getting around the ball more with 70 (i believe you mentioned) so its going to flip, so your going to cover more board and surface will be a premium. I just think an earlier rolling layout will a dead surface will yield better result because you want to get the ball to lay off.

LL--Have you ever tried John Jowdy's "ring finger lead drill".  That should help lessen axis rotation.

Guys,

Alsways room for improvement.  While I continue to use my old dead Ti Messenger with a 4 X 5 drilling!  I really can move left with that thing(no midlane like the rest of the bowlers in the house! when they apply that drilling, hmmmm?)

I am working on less axis rotation, note pitches recommended above!  I also have been using a 1 3/4 X 5 Vibe, and will soon have a 2 X 2.

Regards,

Luckylefty

Guys,

I'm working on everything.  A better night last night with one good game one barely acceptable and one F up!

The positive I am seeing is I finally in my mind am ignoring what I am seeing in practice and on the right and treating the shot like a 35 foot wet dry!  Despite the fact they say they oil to 35 but buff to 40.

I started using the technique I read about on the Columbia website years ago and basically throwing 5 boards wide of the oil line (instead of throwing to the oil line at 10 throwing to 5 or 6) and I am also looking  long to 6.  Started a little strike party second game and then started 7 pinning to start 3rd.  Crowded left and looked firmly at the long 5 and finished out strong after a string of missed single pinners!

Looking around my garage for that plastic ball.

By the way....used one of my stronger balls with a strong Mass bias for nice results!

REgards,

PS I've used this strategy on a 35 shot before and been the high lefty in a league that sent most of them home in the past.

Rightycomplex,

I also used a lightly polished 900 Global Favorite and if I had not had thumbhole exit issues on a few shots (new thumbinsert in that one).  I loved it's reaction playing the wet dry strategy I suggested above!

I believe it has quite similar specs as the Storm Manic...Right?

Pretty spot on. Manic is a little stronger in core numbers. I think the favorite is going to be smoother and a bit more predictable but thats slight.

I am adding a link here that Scott33 sent me.

http://www.blueprintbowling.com/Blog/Posts/blueprint-testing-by-earl-and-supercats.aspx

This link does speak to the subject of different drillings but it does speak to the subject of how much a 60 to 70 degree axis rotation player adds to ball movement!!
Also the concept of effective rev rate based on axis tilt is interesting also.

The above concept of how much more movement one gets with a lot of side roll versus a small amount of side roll is quite dramatic.  Thsi is why I ask my question about throwbot and it's axis rotation for the cgnomadeh test referenced above.

I have recently done a bit of testing with some drillings that are symmetrics to verify some of my ideas.

Please anyone involved in the Brunswick tests above...axis rotation used?

purduepaul at bowlingchat.net was very involved in the ball motion studies.  Ask your question in the General Discussion forum under Mo & Friends and you may get answer (he's not on the boards very frequently).  --  JohnP

John P,

I'll give it a shot I think the answer could be interesting!

Anyone know how to make Youtube go to slow motion?

On this pattern and solutions. 

I'm learning!  And enjoying the learning.

Every part of my game is having to be changed but I'm seeing some intermediate results.

Where my game loves oil and I spent a couple of years bowling in tournaments where it was FTL day!  I got nicely pretty proficient at it!

Now this center with it's Prodigy oil, Kegel stripping, and 35 feet of oil with buff out to 40 is in my opinion one of the most extreme wet/dry 35 feet shots I've seen.  Especially on the left!  Oh did I add they don't have oil for about 24 inches over the foul line.

SO, no more down on the foul line.  No more looking at the dots or arrows. In fact if I have seen a pattern look more like Cheetah as I have seen it on TV?  Not really!  Have I seen a pattern match up more difficult than this one for this revs dominant slow speed lefty with my high axis rotation?  Not really!

But all of sudden I am having some noticeable improvement.  Some from the guys right here! 

Steps taken  1. rotated pitched to the right a little over 1/8!  (Less axis rotation).
2.  Raised my eye focus to the white board running down next to 5(yes the 6 board).  3.  Extended my arm aggressively out to and throw the 6 board while standing 27 or 28. (result more speed and clearing the two foot no mans land desert).  4.  Taking a high pin, power house assymetric pearl and flinging it into that desert near the gutter at about 32 feet.  Result lots of hit, hold(in the dirt), and pin action at the pocket.

Surprises?  I am very surprised how strong a pearl I am using, and how powerful it's assymetric is leading to lots of hit! 

I note that the left side has this wet dry look with the "buff" area reacting like the Mojave.  I have thrown crossover spares into the righty " buff" area from 35 to 40 and note that after practice the hold in that area is unmistakeable and quite nice.

Where the lefties "hold" is in the dirt near the gutter(1 board right in the 36 foot mark of the pattern from 8 to 11 for a lefty is brooklyn plus sometimes MUCH!  For those not seeing this pattern aggressive brutal crossovers far from the headpin are common and funny!

Also, regarding the label drilling above.....seems very nice playing to the end of the pattern for righties  For Lefties 45 degree drill angle drillings with strong mass bias seem to work real well using the Columbia wet dry tip of 5 boards outside of the crown edge noted above.

When reading the description of the strategy of cheetah,,,,that is what I am doing!

While currently most of the telephone number scores are being shot by righties, I believe telephone number scores possible for a lefty that figures out how to play this pattern!  Which to my untrained eye moves like cheetah on the left!

REgards,

Luckylefty
PS anyone like to describe their impression of Prodigy oil?


   

 

Here are my attemped changes
