Stable Drill Help
« on: October 12, 2004, 01:25:06 AM »
Hi All,

I have just purchased a Storm Triple Extreme, i am after a stable drilling that will give excellent length with a very hard continuous arc.

Me: 450-500RPM, fast speed and minimal axis tilt. 5-1/4 x 1/4 up right handed.

Will polish the ball to help with the length.

Thanks

pin 5 to 6" from pap for late flair and length . kick the CG out.

I'm not familiar with this ball but maybe pin up depending on the length you can get normally with the shell type.

some ball polish have a nice length but I find these balls to be to flippy so having the CG kicked out 2.5" along grip line will work for a symmetrical ball.

another nice drilling for Sym. balls is place the pin 4" from pap as high as you can and place the cg on or past Val.

if this ball is aysm. place the pin 3" or higher over grip line and place the MB at 5-3/4" place the pin 5" for later revs.

Stable drill 1.5-2.5 away from PAP.  Cg / mass bias can be swung either to track area of even the VAL.  Revs and hold line and recovers smoothy and controlled with arcing pattern.  With your higher rev and speed it will be fine.  The 6" drilling will hit dry and stand up.  Not my fave for stability. Of course with the Lo Rg drilling you may not be in the left gutter and swinging 30 boards.  It does enable one to get straighter and hits great.

I don't think placing the pin near pap will result in a hard arc.

pins placements at the pap produce and early roll and no real flair.
pins placed in the track are stable and produce no real flair but roll later( pin up)

I'm pretty sure you would want a pin up drilling. I have had a ball( monster bruiser) drilled with pin and ring and cg 1/2" negative. and man it moved on the backed. clean through the heads. this may work.

depending on the oil. just about any pin up position from 4 to 6 inches will promote length. I would swing the cg towards the track for a tamer reaction or near pap for stronger arc. 4.5x5.5, 5x3, 5x6. just l keep the pin up.


you have higher revs with little tilt and I would be concerned that pin pap may roll outand hit weak. how is you axis rotation? with a pin on pap and high

axis rotation you will get length with pin on pap. if you have no rotataion a pin on pap may roll out and not produce a hard arc.

1.5-2.5 form PAP is not near enough to reduce the flare of a Triple Extreme that much.  Stability was the goal. It will work.

ok basic label shift drilling with the mass bias located next to your thumb and to the left if you a righty and right if you a lefty......this is what I drill alot of the mass bias at since most are so strong......it gives that BOOM sound and also is very easy to control
