Pin positions
« on: July 27, 2005, 04:32:30 PM »
How would you get the maximum hook out of a bowling ball.  WOuld it be to put the pin 6" away from my PAP or closer? I told my pro shop owner to drill my Track Animal for max hook.  He seems to know enough about bowling balls, but some of the things he has told me don't make any sense, especially when I got my first ball I asked for a ball that hooked in oil and he pointed out the Brunswick Power Groove Teal/Purple Sanded, which worked good the first couple of weeks on heavier oil then only worked on light to medium conditions).  The first couple of weeks my Track Animal was working great, whether it was the condition or not I don't know, but lately by ball hasn't been hooking a lot, if any.  Last week it seemed like the lanes were so flooded, that I had to come in off the corner.

A ball has the most hook ponential when the pin is placed 3 3/8" from PAP other wise known as leverage. This places the core at a 45° angle to your axis which is the most unstable position.
A Purple/Teal Power Groove that is kinda comical since it is no where near a heavy oil ball. But the proshop operator may see things in your game and know that there isn't enough oil where you bowl to need anything stronger than it, which is a medium to med/lt ball.
Are you sure that it is excess oil that is preventing your Animal from hooking or is it burning up to much energy getting to the break point.
More than likely it is the latter of the two since the Animal will handle quite a bit of oil.

When you ask is it just burning up does that mean are the lanes too dry, because if so then no because I tried my Power Groove from the same line as my Animal up the 1st arrow and it didn't hook either.

That doesn't mean that it isn't still a lack of oil.
The PG has a dull surface and will burn up too if you have left it OOB.
I would be willing to bet that is the issue since most every house has dry lanes in the summer especially out at the first arrow.
Does the ball still have axis rotation when it gets to the break point?

I would change the surface of the PG to something like 1500 polished and see what happens.
The dull surface causes it to want to roll real early maybe even earlier than your Animal.

I already polished the PG. Everybody in the house had problems with their balls not hooking, even the higher rev players had to move right. In this center it is drier inside of two and much more oil outside of 2. My animal's surface was dulled with a green scotchbrite pad.

Oh I see the dreaded reverse block pattern, not very common to find that.
I would either get a ball more suited to HEAVY oil such as a Track Rule GP2, Storm Trifecta, Ultimate Inferno, etc. or dull your Animal then.

How is the Animal drilled?
Have you tried playing inside of 2 with a weaker ball?
A urethane ball may be just the thing.

Pin is about 1-1 1/2" over and about 1/4" up from my ring finger, mass bias down about a 1/4" and over about a 1/4" from my thumb.  I am not someone who knows a lot about ball drilling. Animal is dull.  From what I have heard the Animal is a heavy oil ball.  I polished the PG mainly for my ten pins, I haven't tried it dull since the fall. Before this fall I am going to have the PG and Animal restored to their OOB finish.  Thursday, July 28th is our lasy day of the summer bowling, it is a fun night.  There is another house that I bowl at that is the same reverse block condition, except at his house inside of 2 is so dry that most balls made for medium-heavy conditions will hook off the lane and ouside two your ball will just skid about 50-55 ft down the lane.

Pretty strong drill and dull surface it should work fine on heavy oil.
No other suggestions, wish I could see you roll it to get a better idea of what is happening.

The only way to see if the Animal works is to drill it 3 3/8" away from PAP right?  Which way left or right should the pin go?

I am not totally sure because I have not measued the distance my PAP is, but I think it is roughly 1-1 1/2" from my CG.  SO that in mind the MB should be 4" right of that and the pin should be 3 3/8" right of my PAP right, if not could you tell me how I should have my Animal drilled for maximum hook.

Given where you say the pin is placed I would think it is fairly close to 3 3/8 now. Surface has much more to do with ball reaction than drilling anyway.
Especially since the Animal has an assymetric core, they do not loose as much flare potential when placing the pin at longer distances.
Without knowing your PAP coordinates I can not say where you would need to have the pin placed for a 3 3/8 drilling.
If you happen to know your PAP and can give me a more precise description of the pin and MB placements based off of grip center I can find out what the pin to PAP and MB to PAP are.
Ball reaction is roughly:
1- Coverstock and surface preparation 65-70%
2- Core 15-20%
3- Pin placement and Dynamic weights 10-15%
4- Mass Bias 0-10%
5- Balance hole 0-5%
6- Static Weights 0-2%

My PAP is about 1-1 1/2" from my Ring finger, I will get the other measurement in a couple of minutes, if I can figure it out.

MB is about 1 1/2" down and 1" over from the center of my thumb.  Pin is about 2" over and 1 " up from my ring finger.  Sorry for the explanation but I do not know a lot about ball drilling.
