understanding pin in vs. pin out
« on: August 29, 2014, 01:33:50 PM »
Correct me if I am wrong. Over the years I've purchased balls with CG's close to pins on sym balls - by chance. I noticed that most were "smooth" going down lane. The balls I had with 4" or more pin to cg distance were the old Depth Charge, Toxic, and Fired Up. these had a sharp move at the end of the pattern. So....

Are pin in balls on the smoother side in ball reaction and pin out the opposite?

I picture the pin in more like a figure skater with arms/legs close to the body - spin faster? With pin out balls like a figure skater with arms/legs further out spinning slower...is this correct?

No...to create a 1" pin out or 1oz of top weight, the core is shifted approx 1/32" from the true center of the mass...4" pin out is less than an 1/8" of shift...

Then start. Bowling and quit over-thinking so much

There really is a ton of wisdom in that remark.  Guys can talk endlessly about the "numbers" of their bowling balls, but what really matters is how YOU throw (roll) the ball.

Have you ever noticed that most bowlers play the similar part of the lane they always do regardless of which ball they use?  It's their "A" game.  It's the part of the lane that matches up with their speed, revs, rotation, etc.

You can tweak the ball's surface to dictate length before the ball finds enough friction to change direction, but for the most part you'll play in an "area" of the lane that works well for you.  Talk is talk.  High score still wins (and Brooklyn strikes still count). Free up your mind and bowl like YOU bowl.  Realize that you probably get as many good breaks as the next guy.  The sooner you do this, the more fun you'll have.

Actually, I don't dip my brain into the dynamics of bowling balls. I find it near the bottom of my list when it comes to understanding bowling as a whole. I was just being inquisitive this morning.

I'm actually one of the guys who gets hated on when I "giggle" or give that "Tiger woods type of smile" when other bowlers talk "pin up, pin down - I need length or to roll early. blah blah" or I hear "i miss my mark"....

I'm simple, I keep 3 or 4 layouts I like, use the vortex if need be, and bowl. If I need to play the twig or the 5th arrow, I'll do it as best as I can. and one thing I don't do when bowling, is pay attention to poeple lol. It's funny how my friends/teammates get all worked up over a guy who carries everything.

Simple is good.  It's only 60 feet, not sending a man to the moon...

RG is more analogous to the spinning skater. Lower RG is like the arms being pulled in so the ball Rev's up faster.

The pin simply shows the top of the weight block.

A pin near the center of gravity limits some versatility for drilling a ball without a weight hole to make the statics legal.

A pin near your track reduces flare potential to zero. Pin's positioned mid-way between your track and axis produce the most flare.

Moving the pin up or down moves the bow ties of the flare.

Many drillings like the pin near the fingers and outside the ring finger. This moves the bow tie up, helping to miss the finger holes, gives more length and provides good core leverage for flare.

If you do that with a pin in you will end up with too much finger weight and possibly too much side weight that will require a balance hole to be drilled.

If you label drill a pin in ball it tend to be smoother in shot shape. You will end up with near zero statics and the weight block will be in a fairly weak position.

Asymmetrical balls can overcome this somewhat. But a 3 to 4 inch pin gives you the most options in drilling.
