Dual angle question - is this possible?
« on: May 19, 2017, 08:28:51 PM »
Apologies in advance if this is a dumb question, but I'm trying to noodle thru this... By my own measurements, I have 70-90 degrees axis rotation, which should translate into skid. I have a ball (Vandal #2) that comes out to be 30 x 4.5 x 35, and doesn't move much. I had thought that shortening the angles would help, not hurt. I have another ball, a solid (Melee Cross), that comes up as 70 x 3.5 x 50, which works great.

I know I shouldn't say ignore surface, but for purposes of this discussion, both balls are 2000. The Vandal is lightly polished...

Is the following scenario possible for a low rev lefty on decent amount of oil? Speed is 13.5 on the Brunswick monitor. PAP is 5 x 1

Short drill angle, first transition completes in the oil, second transition is still in oil instead of end of the pattern, so doesn't really get into hook phase too well, and by the time I get to the end of pattern, the ball has done it's dance, all in the oil, never really grabbing, but it's essentially spun it's wheels in the oil... There's nothing left? Ergo, it appears weak.

Forget adjustments, forget alternatives, those are the next questions. Is the scenario itself  as described above theoretically possible?

Thanks

100, I think you're on target. Its.. I can't say I agree. Harder yes, impossible, no. And again, relative. Each ball has it's characteristics, and properly combining the factors should still produce an improvement over what I have now. I should add here, that my efforts so far have not been without reward... Last month, at age 60+, I had my first 800, followed by two 750's. I'm convinced I'm exploring in the right direction.

Apologies, I thought it was clear, but it probably wasn't. Yes, we all know surface comes first, but this is a new DV8 Vandal, my second, polished, that I am trying to get to perform as is it's default characteristic, length with snap. Sure, I could sand it to 500 and get a different reaction, but guys, that isn't the point. The question, restated, is this. Can a ball go thru the first 2 transitions while still in the oil and for that reason come off the pattern weakly?
APologies if I was unclear originally.
I would say yes. My friend had a Lock that put the MB in a very early position along with a pin distsnce that wants to get into a roll vs keep the axis rotstion. It read so early and puked downlane. When it saw volume, you could see the ball revving up, but have nothing downlane. On shorter patterns, the ball shaped more, but still forced the user to play straighter angles as the ball did not have the backend shape as other stuff would. I had them take the ball all the way from fresh 1000 all the way to 4000 polished with just about everything in between. It altered the ball reaction, but still had the same lazy characteristics.Hope this answers the question.

One more thing Lefty... (IMO)The best way to achieve a Skid/Snap reaction on your Vandal is to keep the cover polished and you want a larger drill angle accompanied with a smaller VAL angle. These factors will help with length but also give you a more angular reaction.

Agreed, and thanks. I realize it won't turn a smooth ball like ... say... a Scandal into a skid snap, but in the case of a ball characteristically designed for length and backend, like a Vandal, it "should" compliment the design. Which basically says I may have come down to far on the drill angle. First transition is too soon for my game. And again, head nod to the surface crowd... Yes, the importance is understood. The ball needs to slow down, agreed. We experiment, we learn, we get better.
