Title: Why the 8 pin?...
Post by: carlitopeters on June 26, 2008, 12:09:20 AM
Yesterday I left the 8 pin three times. If it's a 7 or 10 I understand, it feels bad but I understand that I will leave those pins and why. But the 8 and 3 times? Second game I left it after a double and then I proceeded to miss it = 191. Then for the 3rd game I go strike - 8 pin - double - 8 pin. An easy 230 game was 185 instead. The lanes were drier than usual but I felt I made a good adjustment, the 3rd game I think I missed the pocket only once. Well, 8 pin happens. This on the same pair I have my best series (720) and with the same ball I put that number (RedZone - pin just above and to the right of ring finger, CG stacked, PSA at the edge of thumb hole, flare increasing X-hole).

I think it has something to do with the way the 5 pin travels.  I once heard that the 5 5 goes straight back and misses the 8.  I could be wrong though.

Sometimes you carry, sometimes you dont! What really happens is that the ball flies right past the 8 pin without hitting it and the 5-pin is deflected away from the 8-pin and unfortunately nothing flies off the wall to knock it over!

One once in a great while is pretty much bad luck as described above.

When I leave 3 or more on a lane I generally feel there is something wrong with the rack. The 8 is slightly left or the 5 is slightly right giving a little more room for the ball to chop the 5 off the 8.

The bigger cardinal sin is missing an 8. One of the easiest spares on the lane.

The 8-pin leave for a right hander is caused when the head pin deflects off the 2-pin and takes the 5-pin straight back or towards the 9-pin - before the ball can ever contact the 5-pin. The ball continues straight through the pin deck without contacting the 8-pin or driving the 5-pin into it.
This site has great videos showing the leave in slow motion:

and here is a nice slomo:

the 5 pin simply is missing before the ball gets there so you get no deflection towards the 8 pin (of the 5pin) and the 8 pin stands there laughing at your face.

The ball generally doesn't hit the 8 pin unless it is a very high shot.  THe ball contacts on 4 pins in the rack.  For a right hander it is the 1-3-5-9. Lefties 1-2-5-8

Just a  bad luck leave, like others have said, the 5 pin gets kicked straight back (ball is driving hard through the deck) or towards the 7 pin (ball that has rolled out and is deflecting through the pocket)  Either one could/should fall, just some bad luck.

I wished I left an 8 pin one shot last nite. However (I am right handed) I drilled the 8 pin head on.....but watched as I stoned a pocket 7-9....sort of sucks when you are on a 4 bagger and mash the pocket and leave something you cannot pick up....

Some of the ole timers would say...if you leave the 8 pin, it was too perfect of a shot.(if there is such a thing). I guess meaning for a right-hander, entering the 1-3 pocket...either it drives in front or behind the 8 pin.

As one person said previously..."just bad luck"

I would say a tough break not bad luck. It can be explained. Since the ball doesnt hit the 8 pin on a pocket shot the ball drives in a way that the 5 pin goes straigh back instead of taking out the 8 pin. Like you said you know how to adjust for other pins which is good. The 8 is one you cant adjust for becuase there are other variables to take into account other than deflection. YOu have to take into account the rack not being exactly on spot.

Just take it as a good shot pick up the spare and dont let it get to you. And quit the idea of thinking that there is luck in the sport. There are good breaks but not luck. Keep up the good bowing.

I would say a good break is good luck and a bad break is bad luck.  What is the difference?

Bob Hanson, I think, wrote a good analysis of where stone 8-pins come from.  Basically, it's not any one thing that does it, it's a confluence of things that have to come together just right.

But no matter how many 230s turn into 180s, they simply cannot compare to this (http://"http://www.youtube.com/watch?v=NSOTzi67jYQ").

"I don't believe it!!"  Whenever I see a stone 8 pin, that's always the very first thing that comes to mind.

funny thing... I threw it real hard today but had not a single "8er" today
seems that certain entryangle avoid this and with some it can happen more easy..
I guess speed and rev match also play a bit role.

well.. I had days I had at least three 8s laughing at me

i always seem to leave quite a few when i am coming into the pocket with very little angle,

Im so glad people are brainwashed to thinking that if they buy a new ball they will carry everything. And its even funnier when im carrying with my 15 year old ball and they're going flat ten.

Blame it on technology!  The reactive resin coverstocks have been perfected to such a degree that the ball just rips into the pocket once it hits the dry.  As many have said before, the stone 8 comes from your ball driving through the deck and kicking the 5 out a little stronger than usual.  The ball still deflects off the 5 to carry the nine, but the end result is no stike on a high flush shot into the pocket.  That can tick off even the most affable bowler.  

Something as little as not cleaning the oil off your ball between shots can make the difference.  Perhaps if your Red Zone didn't have the weight hole you would have carried those shots. Who really knows? Sometimes it's just the bowling gods keeping you humble.

I bowled four games on the Scorpion yesterday with my Cell and left two stone 8s and a stone 9 in just the first 2 games.  However, I did not leave ANY 10 pins in the entire 4 game block.  I'd rather shoot at an 8 pin than a 10 pin, so I think it's a fair tradeoff...

Kind of sad, but my buddy Nick Meko shot 299 with a solid 8 in the 12th ball. I yelled, thats it 300! and what else but an 8 pin.. Buried the pocket. But I guess it was okay because the very next weekend, he buried a 300 for regional play. Only wish I could of done something like that, where I had 3 279's that day.. lol. A 10 Pin that slid to the 8 1/2 spot, 9 pin, and 7 pin.. Gahh.

A little off-topic but I've always thought the 'prettiest' strikes to watch are when the last 2 pins standing are the 8 & 9 and the ball rolls off the deck splitting them.

I agree with Dan I would much rather shoot at an 8 or a 9 pin than a 10 pin.

That is a good looking shot to watch, and one of those "good Break" scenarios.  Good thing that ball continued to drive through the deck.

i left three solid 8's today in the course of 5 games. the first two looked absolutely great but the 8 pin stood. the 5 pin was pushed straight back by the ball both times. the third one was a bit odd. the 8 pin remained but the 10 pin was "chopped" down by the 6 pin. the ball appeared to deflect thru the pocket slightly instead of pushing the 5 pin straight back. i'm going to attribute this leave to the pins being slightly off spot and a lane that had not been cleaned or oiled. all three 8's were left playing 12 to 2 with my total inferno.
