Pin on NAP?
« on: December 01, 2003, 01:28:33 AM »
I am toying with the idea of drilling a ball with the pin on track, and am trying to understand the right kind of layout that is necessary.

One of my ideas was to pit the pin on the negative axis point while trying to keep the CG in a safer position, but my main ball driller is almost positive this will cause the ball to "air-flip" which he believes will result in instant rollout.

I am not looking for a hook-set reaction necessarily, just something that will produce a very long and less agressive one.

Any tips would be greatly appreciated!

it may be just me but when a drilled talked me into putting the pin in my track, the ball rolled like a full roller.

Use to be a tweener with an inverted track. near fingers and high revs. If I drilled that now? don't know what it would do.

But I have drilled 135 deg layouts for dry lanes and 105 for med-light,wet/dry. both of these with the cg negative.

what I have found with these drillings is you need light top wieght and short pins, 2" and 2-3 oz.

Yeah I have tried negative weight drills before, most recently with a Hammer Solid Vicious.

Ball had 7/8 oz negative side weight with the pin right above the bridge.

Had it polished to 5000 and it still likes to jump early, which is why I am seriously considering a pin-on-track drill.

you may also wnat to pick a core that set's up earlier and is more acr/control by nature.

My favorite for control so far is a turbo Diesel with a 1-2" pin. Pin under ring and cg at 105 deg.

The core on this stands up real quick in the mid-lane.

maybe some other tamer core like the V2 series or some other symetrical that will have more of a tamer back end.


I would vote for a Hammer. I just like the way it hits.

Placing the pin on the NAP is equivalent to placing the pin on the PAP.  The only difference is where the cg ends up.  Neither will flare.  The ball reaction is totally dependant on the cover and the release, you have taken the core out of the equation.

The ball in question here is an NIB Emerald Jackhammer.

3" pin and bad top weight, 1.7 oz. iirc

So if I want to take the core out of play by placing it on one of my axis points, am I to understand that it would be better to place it on my PAP to avoid reverse flaring and/or flaring over my finger holes?

The more I think about it, I guess a pin-on-track drilling is nother but a label drill set up for a lefty, but with a righty's grip? I've thrown lefties equipment and it's reaction is still too flippy, so a pin on PAP would be the best route to go for what I am searching for?

Thanks for all the input guys, I love learning this stuff.
