Re: Danger of flaring the wrong way?

Drilling high track bowlers with pin to PAP distance > 4 3/4" can pull the track up on the holes, but won't reverse the flare until you exceed 5 3/4".[/color] If this does happen, and you pull the track onto the holes, is there any way to correct this with a extra hole, or do you need to ...

Low Flare

I don't know if this question can be posed quite easily, but I will try. Lets say you have two symmetric balls. Both balls have a similar low RG. One has a low diff (0.020), and one with a medium diff (0.040). If you drill them with a 5-1/2 to 6" pin to PAP (and similar val angles), at some poi...

Need drilling advice for two hander with strange track

I'm trying to drill a ball for a guy who bowls in my league. He doesn't use his thumb, and as hopefully you can see from the picture, he goes across his middle finger. I tried to highlight the track with yellow grease pencil. The white tape below his thumb hole is where I estimated his PAP to be. I ...

Re: Layout help

What ball did you drill? What ball surface are you using? With such low drilling angles your PAP is about a P3 and should increase the flare while getting rid of finger and side weight. I drilled a Brunswick Mastermind. I have the original surface on it for now, which is 1500. The CG was not in lin...

Hi all, I have received help on here before in getting my benchmark layout. In general: Right Handed Ball speed off hand (17-17.5) Tilt 25 degrees Revs 275-300 Axis rotation varies (30-70), typically 65 or so. PAP - 4.75 over and 7/8" up. Benchmark: Asym - 25-4.5 -45 Sym - 30 -3.5 - 40 So I hav...

Thanks for taking the time to reply.

I'm going to have to drill up a symmetric or two, and see how I like them.

Few questions about Tilt

A have a couple of questions. if anyone can shed some light on these topics I would really appreciate it. 1. If you look at the Dual Angle Ratio versus Tilt chart. It appears pretty obvious that the higher tilt that the bowler imparts on the ball the smaller the ratios that they should use. What is ...

Re: Brunswich Nexxxus f(p+s)

Thanks for the reply. I did notice that hitting it with 3000 didn't seem to change the cover much. I'll see how he likes the current cover, and adjust accordingly.

Thanks!

Re: Brunswich Nexxxus f(p+s)

Thanks for the reply. So given the situation where you had a high tilt bowler, and they are having trouble with their ball finishing on a pattern with more volume, would you recommend a symmetric over an asymmetric ball so that it will give up it's tilt quicker? Or is that too simple a situation? I ...

I have a question if anyone has the time. I drilled this ball for a friend today. Specs: Revs approx 250 - 275. Speed - 16-17 off hand. Tilt 30 degrees Axis rotation - Close to 90. I put a piece of tape on his PAP and basically it is pointing straight at the bowler, and fairly high above the equator...

Re: Do different cores equate to different rev rates?

In my opinion I think the lower RG ball will have more revs off your hand. Torque - I * alpha Torque = Torque applied to the ball I = Moment of Inertia Alpha = Radian Acceleration Torque is the amount of force through a distance (radius of ball). Assuming the same release and same weight ball, the t...

Re: Drilling for low rev spinner

Right Handed Speed 17-17.5 at foul line Revs 275-300 Axis Rotation 45-60 ... but I can go 0-90 pretty much. Axis Tilt 27 From the Wiki my sweet spot is like angle sum of 80 with 1:1.5 or 1:1.75 ratio. I am in the category of more speed dominant. On typical house shots, I get good entry playing down ...

Re: Drilling for low rev spinner

Thanks for the reply. I have seen the chart before, but was never really sure what forward roll truly meant. If you (or anyone else) doesn't mind answering another question or two, I have 2 quick questions. 1. I see on that chart that it says pin distance of 2 3/4 (for asymmetric) promotes more side...

Re: Drilling for low rev spinner

Hello Drew, Track flare for asymmetrics will be roughly the same from 4" - 6-1/4", but for high tilt players, pin - pap distances from 4" to 5" will read friction and cover more boards, while pin - pap distances from 5" - 6" will give you more forward roll. Cheers, Rob...

No sir! Surface changes will just increase, or decrease, the total amount of flare. 2 minutes in the penalty box!
