Long/Short Pin benefits and disadvantages
« on: May 10, 2009, 11:35:01 AM »
I never gave much thought to the Pin length, but last year I was so happy with my first [Hammer] Anger, that I decided to get another one. When I got to the pro shop, I was told that they only had one with a relatively short pin (1 1/2 or 2 inches it seems), and asked if I wanted to wait a few days for one with a longer Pin to arrive.

Being into immediate gratification, and not really understanding what the pro-shop owner was trying to tell me about the ball, I decided to go ahead with the purchase.  I use both angers and don't notice a huge difference, except that the one with the longer pin (3 1/2 to 4 inches) does seem to be more predictable and go a little deeper and have a slightly better backend.

Is this a result of the Pin diffeences, or just psychological on my part since the pro-shop owner put the idea in my head?  

I had the drilling of the first Anger (with the "long" pin) copied onto the second "shorter pinned" Anger, and to the best of my knowledge, everything else about the two balls is the same...except the PIN length.

Just curious and hoping to be educated. Not a problem I actually need to correct.

My experience is , short PINs for heavy oil drilling ! Long PINs for dry conditions. This is what works for me...handmeDN

I have a dumb question about the information contained in this link. If the true CG of a ball is 0.04 inches away from the dead center of the ball, what determines where on the ball the CG stamp is placed? Do you just take the shortest path from the CG out to the surface?

So would it be an over-simplification to say that a shorter pin will contribute to an earlier roll, and a long pin to a later roll?

This is true usually because a shorter pin forces you to limit your drilling options to pin-under drillings. And a pin-under drilling, in most cases for most bowlers, is going to roll earlier than a pin-over drilling.

You could take a short-pin ball and drill it with the "Tommy Jones" layout and it would probably still react like a Jones ball -- but it would also likely be statically illegal unless it had a really low top.

Even with a higher top, you would just need to drill the fingers extra deep. Yet most people dont do this because they dont understand that you can do this. It is also alot easier to do this with people who use grips. Two 31/32 holes going down say 3 inches can get alot of weight out. Even more if you have alot of top and you take them over 3.

The fact of the matter is, if you have a 1" pin and a 3" pin. The difference between the two when you go down into the ball at the core is at most an 1/8 of and inch and that is giving it the biggest difference. So there is somewhat of a difference but not enough to really see a change. Where most people do see the difference is like stated above, in the layouts. Most people will use a short pin with a more roll type of layout, most of the time because they are scared to put it pin up and very away from the normal spots for pins. The same is true for longer pins.

I have two storm jolt solids. The first one has a 1 1/4 inch pin with a 5 x 4 1/2 pin under ring, my pap is 5 1/2 over by 1/2 up, and the second one has a 2 1/2 inch pin with a 4 1/4 by 3 1/4 pin under ring with a small hole in the thumb area. The first jolt with the short pin actually goes way longer down the lane than my second jolt solid with the 2 1/2 inch pin. So, having a shorter pin does not always mean that a ball will hook sooner or be smoother.

The first Jolt is 3/4" further from your PAP, that should make the ball go further down the lane. Combined with the cg being kicked out with a hole on the longer pin ball you will see a pronounced difference in reactions between the 2.  More than any pin distance will show.

Pin length doesn't create reaction.  It only makes it harder or easier or drillers to drill a ball a certain way.
