laying out a total NV...
« on: March 18, 2007, 08:54:52 AM »
I was going to practice layouts on my total NV.  The problem where i am getting stuck is the pin, cg and mb dont line up.  The mb is farther right if you would draw a line from pin through cg.  Where do you start to layout a ball when its specs are like this?  Thanks!

First, If you are a rh bowler, that cg placement sounds like a good thing. Basically you ignore the cg, and place the pin and mb where you want it. What kind of layout did you want, how far is the pin from the cg, what is the topweight, and if you draw a line from the pin-mb, how far to the left is the cg? I will try to help. Joe

kind of like this? http://img374.imageshack.us/img374/5489/spa0219oh0.jpg

it's not a hooking beast drilled but it does play the outside line extremely well.

As Cobalt said, that could be a good thing if you are a righty, unless you wanted to use an X hole to tune. Here's mine with drilling #2 from the drill sheet (4 1/2 pin to PAP, 45 degree MB) and with the CG being shifted, the statics came out fine without having to mess with it at all. I knocked the polish off with a 4000 Abralon to bring the break point in a bit closer, but its still plenty strong.

if my driller would have told me that i more than likely would have gone with that layout but originally i was thinking i would get one with pin/cg/mb all lined up

i asked for pin up with cg kicked out. the wierd thing was i came in on wednesday(not sure if this is the exact day but you'll get the point) and he said my ball was next to be drilled but it will take a 30 minutes but i had no time so i told him i'd come back the next day. he also had a setup in the middle of the proshop with the ebonite balls that are currently out and it had the TNV with all the other out right now. When i came back in the next day on the rack i noticed no TNV but all the other balls were still there and he said he was just about to start drilling my ball. So now that i look back on it i think he might have took his display ball to drill as mine and i originally had another ball but he drilled this one.

As of the reaction it's not all that strong. It works fairly well on medium-heavy oil but i can only play an outside line with it as soon i as start moving in i lose a decent amount of reaction in the ball. At this moment i'm going to be getting a new ball after selling my Total Inferno(drilled by the same guy that didnt' match up well with me) and a Scorchin (also drilled by the same guy and that ball didn't match up as well) so for my next ball i've heard great reviews about another driller in an alley not far from me so i'm going to her next time i get a new one.

yes im right handed and my ball looked liek yours slacker.  I was looking for a layout like drilling #1 from the storm shift ball.  I beleive 4.75 pin to pap and 5 mb to pap.  With everything being out of whack could i still use the 4.75 & 5 drilling or would i have to change something?  Thanks again guys!

OH bowler, what are your axis coordinates? If you draw a line from the pin to the mb, how far away from that line is the cg? Also, what is the topweight and pin to cg distance?.

A down axis coordinate is unusual. It means the track is closer to the fingers than your thumb. Anyway, without seeing the actual ball, using those axis coordinates, you may end up with the cg slightly negative and finger positive, may need to drill ring finger deep to make legal. I haven't seen the storm shift #1 Layout. does it have the pin over the ring finger or below?
