High tracker--Pin under ring?
« on: July 05, 2008, 05:31:22 PM »
Hey,  I was just wondering why people often say that it's bad to put a pin under the fingers if you have a high track.  I track quite high, and I had my Special Agent with the pin under ring.  It rolled very nicely.  Granted, it a had a very weird track flare on the ball, but still rolled very nice.  Any input is appreciated.  Thanks,

Zach

Pin under the fingers for high trackers does not generate weird flare, but you risk that the ball, esp. when it is a high differential piece and you have lots of revs, tracks across the middle an even ring finger, what will have negative effect on traction and a stable back end reaction. This does not happen on any piece drilled this way, but can happen, as well as negative flare on a high MB ball when you put the MB into a high tracker's track area. It is just a risk you can avoid before you punch up a ball.

Therefore you find in some drilling instructions a so-called "safe zone" for pin placement in some balls - it normally excludes a triangular area between initial and final track under the fingers for high trackers.

This layout, for a high tracker, can possibly cause a track to roll up over the middle finger, thumb, or even all the way over the ring finger in some cases.

A prime example is the Total Inferno. I track high as it is, and I drilled a Total with pin directly under the ring finger, which causes the ball to roll over the thumbhole. That being said: the ball reaction I was looking for with this ball could not have been attained as well with a different layout, so it's not always 100% necessary to follow the specific instructions of a ball manufacturer. Don't be afraid to toy with layouts, because a ball rolling over the thumb or not will be less difference in carry (in some cases) than the ball hooking 2-4 feet further down the lane because the ball driller used a different layout than the perfect one for the desired ball motion.
--------------------
I am a righty, with a high rev rate (400-500 rpm) and semi-high speed (16-17 mph). Book average is 202, and I consider myself one of the most versatile bowlers I know I can play a stroker, tweener, or cranker line, depending on what the shot calls for.

For a game based on the principles of science and math, bowling sure does have a bad habit of being illogical.

I'm a high tracker and pin under fingers doesn't work for me at all..

Tried it on my Ogre Solid but it's been plugged and re-drilled with pin above fingers..

Like it better now..

Pin on the side of ringfinger works for me too..

I've got a high track, and I've got balls which are both pin up and pin under. The majority of my equipment is pin high but I can bowl well with either one or the other, depending on the lanes.

I think that the location of the track appears to be less important in deciding the pin high/low than the combination of the bowlers revs/speed and the nature of the ball to be drilled. Most of my stuff is pin up because I used to be a little rev dominant. Now I'm a little more balanced, the high, long pins give me a nice even reaction, with nothing too extravagant.

So I have a rival with the pin directly under my ring finger, about 1/8 down and 1/8 left(right handed) from the middle of the hole.  On this particular ball my track is about 1/2" from my middle finger.  Doing a Rico layout would make it flare over my middle finger?

If this is the case, what is it that makes a ball track higher when the pin is lower?  Does it necessarily mean I would track a little lower with a pin up layout?  Is there a way that I can track low by learning or is my high track something I'm stuck with because of how I roll the ball?

The balance hole is a very important part of the Rico layout.  It is located 6 3/4" from the pin on a line through the cg (or mb for an asymmetric ball).  That puts the large balance hole in the positive thumb quadrant, which raises the bowtie enough that most customers don't hit the finger holes.  Still, if your track is VERY high and/or inverted, I would recommend staying away from Rico.  --  JohnP

My track is like this

--------/-----------
-------/--o o-------
------/-------------
-----/--------------
----/------0--------

Closer to the middle and far away from the thumb.  It's about 1/2 inch from the middle finger.  Not super close but close enough for me to be cautious.  is that too high for me to do a Rico?  I bet it is.

well funny thing (lot's of funny things lately)

I am getting a ball with a short pin drilled tomorrow... pin under ring is the plan.

But I am not a high tracker anymore. but my track has moved 1" away from the old one... but I can throw it like in the old days

I call it "stroke" it

Let's see if it clips the fingers but I don't think so

Are you sure that's the first track ring?  Or could it be the third or fourth?  If it is the first, your track is inverted.  I would not recommend Rico - too high a chance of hitting the fingers.  --  JohnP

Well, that's where the rack itself is.  As for the oil rings I can't say for sure but if by first ring you mean the one closest to the holes, it's pretty close to that.  It's actually not as far away from the thumb hole as I have made it looked, but it is indeed closer to the fingers than to the thumb.

The best way to determine your PAP (and thus your first track location) is to use a non-flaring ball, one without a dynamic core.  Then adjust the location of a piece of white tape until it looks like a stationary dot as the ball rolls down the lane.  If the vertical component of the PAP location is "down" your track is inverted.  --  JohnP

When my pro shop measured my PAP he measured 4 3/8 over and 3/8 up or something similar.  Definitely not down on the vertical component.

Then your initial track ring is closer to the grip centerline at the thumb than it is at the fingers.  You're seeing some of the later flare rings, the flare carries the track into the configuration you drew up.  --  JohnP

My track goes something like this....
On my urethane without core, track goes on right side or over thumb hole and over left finger.
With low flaring ball, on the left side of left finger and over thumb hole...
No tilt.
Is it full roller or what?
Can I use Rico?
