Drilling Suggestions for strong pearl
« on: April 14, 2009, 01:28:39 AM »
getting ready to punch up a new peice.  I have a few holes in my arsenal i'm trying to patch up.  I need a reaction thats clean through the heads but still has some pop.  I went with a low rg/high diff piece just for hitting and b/c i seem to get great length with any piece i drill from pure axis tilt.

Now this seems to be a no brainer, EXCEPT my past history with pearls is not so good.  I get a verrrrrry skid flippy rxn and it's not controlable.  I want something clean through the heads (once again) and some pop, but i don't want the ball recovering off the dry sideways.

I'm goin with a 5 - 5 1/4 pin-to-pap drilling for the length.  should I go Pin up or Pin down?  should i shift the imaginary MB out close to the VAL to combat that jerky down-lane rxn, or keep it closer to the thumb for the POP i'm looking for?   Thanks in advance.

i usually go pin down, if im trying to get away from the hockey-stick reaction on the dry. if you want a reaction that allows you to still cover some boards, i would keep mb closer to thumb, so it will still retain some energy going down lane. let us know what you went with and what ball.

good luck!

I will be going with a Storm 2nd Dimension.  Drilling is still up in the air until i talk to a couple local storm reps.  We'll see.

I agree with inverted I would try a 4-1/2 pin to pap as using a 5+ inch pin will make it tougher to use on heavier or longer patterns.
4-1/2 pin down will allow the ball to clear the heads but be smoother off the break and not left turn off the dry.

The only thing you may have to watch for with pin down is clipping the holes. You should be ok just be careful. Your driller may be able to tell you if you will be ok.

My 2nd dimension is drilled with the pin 4-1/2 up and mb 1/2 way b/w thumb and VAL (3 or 3-1/2 from PAP can't remember off hand). it gets good length and has good pop at the back.

The Second Dimension is going to be pretty darn skid flippy out of the box.  You'll need to adjust the coverstock.  Check out my video review of it on a sport pattern -- I adjusted the surface to 2000 abralon then polished it by hand with Snake Oil, and it's still very strong off the friction.  Also, it's such a strong ball (very strong coverstock, medium-low RG core) that I would not recommend putting a stronger, higher flare drilling on it.  Use a lower flare drill, then use surface to adjust the reaction shape.

Based on this, I also agree with Inverted 1.  If you don't want too much length and then have it fall off a cliff (so to speak), I'd go with a 3.5-4 inch pin to pap to get the ball started a little earlier so it won't have so much energy stored to be released all in the backend.

I recently did this to a Mars.  Knowing that the ball was a little flippy (and I also tend to make u-turns on the backend), I went with a leverage drill to offset it and it just gives me a continuous strong and smooth movement throughout the lane, very nice.  Hope this helps some...

i ended up using a Dual Angle drill on this 2nd dimension.  Found where the MB would have been and used the for reference.  60* x 5" x 40*.  this put the pin about and inch to and inch and a half above the ring finger and left ~2" pin buffer from the VAL.  i didn't need a weight hole but one might be added to tune the reaction at a later date.

review:
THIS BALL HOOKS A TON.  I wish i would have went with a 5 1/2" pin-to-pap b/c this is a monster!  I couldn't throw it on a higher friction syn surface first shift, it just got into a roll too early.  The second league i bowled in at a diff house had a lower friction surface and it rolled great.  This ball also hits like a tank.  I'll prob end up putting in a flair reducing weight hole to tame down the rxn.

I don't know what the oob surface on the ball is, but I'd try sanding to a higher grit before adding the balance hole.  --  JohnP

Try 4000 Abralon, first unpolished.  If you don't like that, polish it.  --  JohnP
