How many have tried the 315 degree drilling?
« on: April 08, 2004, 04:01:46 AM »
I have a ball I am going to drill like this because the is not much else I can do with it with the 1" pin and all.  I was wondering what kinda reaction you got out of it.  I have read about it giving a hard arc with medium length but want to hear from people that have tried it.

I just tried a Sonic-X pearl with it and it (& I) bombed. The normal advice from people who know is to use a ball with a built-in, designed-in AND MARKED Mass Bias. I think miine failed for just that reason - didn't have one; core is symmetrical. Be sure yours has a built-in MB, don't just measure 6 3/4" from the pin thru the CG!

A word to the wise is sufficient.

You can still drill a ball with a 0-1" pin in the normal way; place the pin where you want and can, angle the core the way you want/need. Th eball will hook earlier (however much and where it hooks) than a longer pin-CG distance and will flare less. The ball is the ball and will react the way your release, the lane oil and ball's design will permit.

It is an Ebonite Shooter so it has a marked mass bias.  The reason I got it with a 1" pin is because I won it on ebay (for $70.00 shipped, well 69.95 to be exact) and in the discription they said I could request a pin a top weight but it could not be for sure that I got it, I asked fo 3-4 and got 1", oh well now I can try the 315 drilling.

The ball doesn't have to have a marked MB, but a symetrical
won't do you any good.

I have a Charcoal Executioner, drilled lable leverage, and one
drilled 315 pin in the leverage position.  The ball dosen't
have a marked MB but there is one there as the neck of the core
is tilted.

To think about the cores the two are just about 180 from each other.
The 315 gives the ball the feel of a higher RG ball (for mae at least).
You can feel the shift in weight due to the moving the neck of the core.

I am still playing with the ball, but I do get the hard arc, almost like
a hockey stick that is rounded instead of the sharp break.  You get the length,
but the violent skid snap on the ball, and I even have the ball polished to
1000.

They say the drilling alows for release mistakes.  I am still playing with that
too, trying to force mistakes.

I don't really think the driling is for the stand left throw right bowler.
I haven't tried that release, but I will.

Last night I took it and was playing straight down 10.  The ball would arc in
and would finish light.  I think this is more because it was first game, fresh lanes, and 1000 polish.  I was playing right on the edge of the oil.  Mid 1st game, it was moving a little more.  I kept moving left and it was holding the line until the heads broke down.

All in all, it is an interesting drilling to play with.
My only advice is if you are going to try to do a comparison,
I think you need the same ball drilled you regular way.

I've tried this in many Symmetrical balls and it's worked fine.  Some of the best reactions I've ever had.  I've tried it in an EZ Money, Ebonite Stinger 2 Piece and Columbia Pulse solid.  You don't need a ball with a pre marked mass bias, just something that's very core aggressive.  Many people try this with a weaker ball already which completely kills the reaction(much like charlest did).  You won't get a good read of what the drilling can do for you unless you use an aggressive ball or if you have a ton of hand.

Does this drilling require the ball to have 0-1" pin and low top weight?
