Author Topic: Q: about "reverse flare" and "inverted flare" (Read 7344 times)

JessN16 · « **on:** February 21, 2008, 10:42:03 AM »

I know what "reverse flare" means and what triggers it (i.e., long pin-to-PAP distances). What I don't know is, what's the big deal? Other than maybe clipping a hole, does it matter that the flare is "reversed?" What does this do to ball reaction?

Also, someone posted their PAP the other night as being "4 over, 1.5 down, inverted." What does this mean? Again, what does it do to ball reaction?

Thanks,
Jess

an inverted track tends to move away from the thumb.

What causes an inverted track and is there any disadvantage to having one?

Bowler19,

Your "inverted" pic looks exactly like the track I get on my Rico drill.

Reversed flare will not affect ball reaction other than any affect from hitting the holes. Full roller layouts are specifically designed to reverse the flare so it is away from the holes.

Adding to the other comments, an inverted track is one that has a negative, or down, vertical PAP component. This will be any initial track that is closer to the grip centerline at the finger holes than it is at the thumb hole.

I have been told that track orientation is a result of which finger exits the ball first. I think if the ring finger exits first the track is inverted. An inverted track does seem to affect ball reaction, making the ball break earlier. Folks with inverted tracks hate dry lanes. -- JohnP

JohnP,

Thanks. That was very helpful.

That's an understatement!!!

I'm 4 3/4 x 3/4 down and I polish everything!!! When I encounter dry lanes, my loft helps out a lot but I have to (MUST) chase oil!!! Also, with my inverted track, I don't have to "wheel" the ball as most crankers do. I favor 3-4" pins and usually have em above fingers. I've a few balls with pin under and left of middle finger (I'm RH), as well as under bridge and ring as well. Either way, majority of the balls thrown have strong backend movement. Only 'arcing' ball I have is Black Widow Solid (could be the drill as well). My fix for dry is loft!

Explained very well JohnP

P.S. One more thing... I've learned 2000 abralon polished works wonders FOR ME, no matter what ball it is (barring an uncharacteristic flood of oil)

I had a used PG Dry/R that had a weird weight distribution inside. Ball was drilled pin above bridge (my PAP: 5" over, 7/8" up, high track), CG slightly swung out (~75Â°), a kind of 5x5 drilling for a smooth and late reaction.
This ball made my pro shop owner look confused - something I have never seen before. The ball needed an immense weight hole, though, and also the finger holes had top be drilled so deep that all the 3 drillings touched in the ball center! It was barely legal.

As a side effect, the ball flared backwards (across the thumb hole), and it hit like a turd. It just skidded all the way down, much like a polyester, and was very unstable at the break point. Total crap, and I had to dump this piece of junk since you could not use it for ANYTHING...

Reverse flare is the best way to kill the ball reaction and its usability. This IS a big deal.

Dizzy -- You had a ball that had something wrong with it. The bad reaction was because of the internal problem, not because the flare was reversed. Actually, all flare reversal is is a moving of the track's bowtie downward so that in the grip area it's flaring opposite from normal. Just think of a normal flare pattern with the bowtie slightly above the fingers. Now mentally move that flare pattern down so that the same bowtie is at or below the thumb and you have reversed flare. -- JohnP
