I just bought a Yeti with a pretty short pin length (about 1-1/2") and I was just wondering if anybody has something similar or if anybody can recommend a good drilling for this pin layout.
-
well there isn't a whole lot to do with a short pin. You're pretty much stuck with using a pin-down layout.
Probably something with pin below bridge or middle finger with cg kicked out a little. The actual numbers will vary according to your PAP
-
So I should not use any of the suggested layouts that came with the ball?
-
Throw away the drill sheet!!! Go to a shop ask the driller if he can do anything different. Short pins on symmetric balls don't mean that you have to settle for a pin down. Granted, I'm not discrediting what SV is saying because he's right. Most times, short pin= pin down. You can go pin up if the driller buries the fingers to ensure statics. Just nothing dynamic.
The Yeti is a very dynamic ball all its own. There are just more variables, like grips or no grips, span, etc. But see your driller they can help a lot more.
-
Yea, I already have pin down stuff including a Mission X pin down with a short pin. I was wanting to try something a little different.
On the Yeti, what would putting the pin down lower in the palm area do?
-
Will give you a boatload of thumb weight and at that point, you could use a Double thumb or P3 weight hole increasing flare and making the ball more aggressive.
-
Umm, no one has asked what the top weight is on the ball. How much top weight does the ball have?

slipped my mind. Plus when he takes it to the shop they'll be able to weigh it. We're just speculating on possibilities.
-
you can also keep the pin even with the fingers and go with a pin anywhere fron 3-5" from your pap and use a p2 or p3 location.
Your proshop who is hopefully drilling the ball should have no problems helping you with that.

3.0 oz top weight.
-
Plenty of options. Drill away
-
You shouldn't have a problem unless you go FAR off the center line. Depending on your span, you can go pin up and drill the fingers extra deep.
-
Very easily stated and I hear a lot from pro shops.
"Drill the fingers much deeper".
What is the effect of doing that in many cases? In many balls the area near the pin is sometimes the densest part of the weightblock and a flip block?
Anyone have the feel of the general change in reaction by going an inch deeper in both fingers, Versus standard depth?

You drill the fingers deeper when you'r trying to shift static weight because you have a short pin and put the pin above the fingers. You can drill the fingers normal and add a weight hole by the fingers as well. The weight hole location or the fingers being deeper slightly lessen the diff, and raises the RG.
I would never drill the fingers holes deep just because.

IMO, the fact that USBC still has the static weight rule in effect is stupid. It's paramount to dusting off a atomic bomb before you drop it because you don't want the dust to somehow hamper the destructive nature of the bomb.
-
Give a ball 3-5ozs side weight and let us know if your opinion changes.
-
A 15 lb ball is 240 oz. I honestly don't see how 1 to 2% of that matters any more.
-
After playing with bp software it shows a significant and undesireable affect. USBC has done studies with Mo that show as you approach those numbers it does affect the ball motion.
My question is does the usbc rule actually affect you? Who and how often is the static weight of your bowling ball checked? Honor scores? Nope. Local tournaments? Nope USBC Nationals? Yes
So you like many others can be very illegal in static weights and never be affected. See problem solved.
-
Is there a difference in final numbers post drill between drilling the fingers deeper vs a P1?
-
couple of thoughts.
For Kidlost. I don't drill for profit but for fun. Typically thumbholes to 2 1/2 inch and fingers to 1 1/2.
Of course all discussion regarding drilling fingerholes deeper was regarding the above discussion of short pin outs and with the pin up and the cg near the fingerholes. Of course the necessity of doing it was the reason why discussed.
I guess the link that you took me too was how to drill a double thumb weighthole if the ball was not set up for thumbweight(ie cg down). I get it....drill the fingers deeper, create thumb weight. Voila Double Thumb or P3 weight hole.
The other question to Impending Doom.
Have you tried balls with dramatic side weight say 2 ounces on a wet dry before the weight hole? It is quite revealing how much recovery there is off the dry and how much skid there is when the ball is pulled in the oil? That is why many drillers will keep drilling to even negative on these situations to reduce the over under.

To a extent you guys are arguing semantics...unless you do a true controlled test it's all conjecture...there are too many variables when making certain statements as well as gauging ball motion by an individuals perception of motion.
When I was still drilling professionally I drilled thumb holes 2.5-2.75" deep and fingers 2-2.25" deep, by the way.
-
I drill for me not for others.
The title the effect of drilling finger holes deeper says a lot.
Look at the numbers on the core prior to drilling an x-hole and the difference in finger hole depths. That is the information most benefical to the question you asked. It is discussed else where as well that once you go beyond 2-2.25" on finger depth the numbers begin to lower the diff and raise the RG. It may reduce the desired results one original wanted.
-
Really, I am trying to learn, so much good information out here!
Just my note on drilling is only related to the fact that I understand the most basic of cg location starting top weight relationships. With my size fingers thumb and inserts my depth of holes seems to leave finger thumb the same as the cg location expectation. I will double check that soon due to a switch to urethane slugs for my thumb.
The information on hole depths link was helpful! Also, Kidlost further posts or discussion of these items referenced or linked would be very helpful.
I do see the subject of this post relates to "Drill suggestion for Yeti with Short Pin".
but it has recently morphed "Short pin CG up drillings". Right now I have a few 2 inch pin out NIB balls I want to pin up(for my local shot) and was wondering about all of this.
For both Kidlost and JustRico. Kidlost has referred to weighthole quadrant references by JustRico. I would love to see a link to that post.
Thanks,

PS just yesterday I set up a cg up one inch cg out 1 1/2 inch pin way up Freeze starting top weight 2.75. I love the reaction, illegal now and cg location is pointing to a 1 1/2 inch up from PAP weighthole. I want to see retention of current reaction to slightly faster rev up. Ideas?
-
Lucky this is my point, you are basing your views off a single instance and your viewpoint only, you can't do this. Making the comment of seeing a greater retention could very well be a brand new bowling ball, this less wear or burn on the cover.
If you have shorter pin to CG balls, instead of distorting the core my drilling the holes deeper, merely move the pin 1/4" farther from pap and place the pin under or simply drill the pin out.
Keep in mind, there are no absolutes in drilling, we know the probabilities of safe layouts. Everything is going to be first & foremost surface and where & how the ball slows down...and understand, being left handed the surface or topography of the lane is different than on the right side...thus creating an illusionary ball motion in comparison to the right side.
-
Illusionary reaction? I don't comprehend?
More oil, less surface/lane topography roughness I do understand. Different for same drilling on right with a mirror bowler of myself, I do understand also.
4 3/4 pin to pap, up enough that the pin buffer is 1.5 up over an inch higher than ring. Would that be the same as say 5 inch pin to pap under ring using the 1/4 inch rule?

Illusionary reaction is what you think you are seeing...in most ball motion the minds eye perceive motion created by lighting or color of the bowling ball or even side to side friction.
