Re: long full roller

A "long" layout? Do you mean a layout that makes the ball go longer? (Seems right, but just making sure). I would simply choose weaker cover/core balls (low end reactives) and/or weaker surfaces (2000, 4000, or polished). If you want a stronger ball with a weaker layout, I believe you can adjust the...

Re: Very strange

Measure your PAP when you bowl upside down. Then measure the layout for when you throw it upside down. Maybe the pin-to-PAP distance is shorter, resulting in more flare- which usually results in more/earlier hook.

Re: *NEW* - MOtion Hole - Video - How To & Demonstration

[/color] Thanks for the clarification. Since the 10" distance is very important, based on your research, do we move this tape, when necessary, ONLY on a radius of 10" from the pin (left or right) to clear the flare and to maintain the exact 10" distance when moving? This is not clear in any instruc...

Re: Pin over/Pin under

Since I asked the initial question I feel a need to add a point here. I asked the pin up/pin down question to see what the general thought was about that. My driller uses the dual angle method and does try to layout a ball with my best interest in mind. However, everything I currently have is drill...

Re: Pin TO PAP Distance - Asyms Vs Syms And Retaining Tilt

5" pin-to-PAP distances on asymmetricals are tricky- very, very tricky. I've seen dozens of bowlers struggle with heavy forward roll when promised big backend with strong asymmetrical pieces. I've seen plenty of bowlers get great recovery in similar situations with similar pin distances. One of the ...

Re: Reducing forward Roll

A P1 will delay the second transition. Try that before a total plug and redrill.

Also, if the pin is near the finger holes, you could drill those deeper and get a similar effect.

Re: Question about the rg of of a bowling ball.

I'm still left with a lot of unanswered questions from previous posts that no one has explained. I'm eager to learn but in all these posts I'm still looking for confirmation and/or explanations. Why is it that the RG of the ball is one of the largest influences of ball motion second only to COF var...

Re: Question about the rg of of a bowling ball.

Interesting - hopefully Steve will chime in and clarify. The function has to level out at some point close to the high rg axis because the rg surface is continuous, so it can't actually BE a cubic (can it?) (just modelled well by one between high and low rg or for one half of the ball). Are there a...

Re: Question about the rg of of a bowling ball.

Not to interrupt the debate, but a little more back to the original question. Low Rg layouts. One of my favorite layouts, is a 25 x 2 x 45. Small angle sums, and obviously a lower diff drilling including a p1 hole. I would love to see the rg numbers on this, and compare it with the different rg val...

Re: Question about the rg of of a bowling ball.

This is one of the few times where my lack of attention in my college math classes begins to show. I've got no idea what you're talking about here! LOL! Which part? With a linear relationship, the RG of any axis could be determined by a function RG=AX+Low RG, where X is either the distance from the...

Re: Question about the rg of of a bowling ball.

LabRat wrote: With a 2" pin-PAP the rg will be roughly .3 to .4 x (differential) + (low rg).
Anyone know if the change in rg from low to high axis is linear or sine function?

When I asked Steve, he said it was a cubic relationship with r^2>.999.

Re: Question about the rg of of a bowling ball.

Note that the differential ratio was dropped from the regression due to what is called multicollinearity. It was not dropped because it had little effect or an inconsistent effect, but because it overlaps with both total differential and intermediate differential. I think the regression should be ru...

Re: Dual Angle resulting in pin down layout

After trying to figure out how they were that drastically different based on how the holes could've changed the diffs, I finally noticed how much the Low RG moved in one of them. The final pin-to-Low RG must have been near or more than 6". Another variable that's difficult to account for. Blueprint ...

Re: Dual Angle resulting in pin down layout

I agree with what you're saying entirely. Here's what I'd like to do (but would take quite a bit of work): Using Blueprint: 1) "Drill" a symmetrical, weak asymmetrical, and strong asymmetrical using average spans, hole sizes, and a "normal" PAP. Record the RG of the PAP, the real pin-to-PAP distance...

Re: moving track / bowtie by balance hole

Really large horizontal component with a small or negative vertical component to the PAP? Like 6" over by 1/4" up or less? Maybe even further, like 6 1/2" over?

That's the only thing I could visualize that would possibly hit that hole (based on Triplicate's screenshots).

Re: Hole 1" down the VAL?

It might be an effort at manipulating static weights. He might just have wanted more finger weight and less side weight. But as far a measurable effects from a 1" down the VAL balance hole, you could expect to PSA to move towards the VAL, but less than 2" down the VAL hole. One might also choose thi...

Is it just me, or is it darn near impossible, using the dual angle method, to stay within the guidelines (90/10, 70/20) and end up with the pin below the fingers? Have tired every configuration I can think of, and sums exceed 160. What am I missing? It's not so much that I'm enamoured w/pin down la...

Re: CG relevance for symmetrical layout

Both affect the pre-balance hole static weights, which can limit the placement/size of a balance hole. The pin length and OOB statics as well as the ending placement of the CG contribute to whether or not particular balance hole placements are allowable or feasible. Thus, as said before, the "drilli...

Re: Negative Tilt

So really there are no set rules for negative tilt. It all depends on the PAP and initial track. Then all you need is a full understanding of how to manipulate the axis migration about the Rg contour of a given ball, have Blueprint software or a previous guinea pig experiment. Sounds simple enough....
