If you want to be able to use the ball in some oil, that may be more length than you're looking for. I'm not saying that it won't work for you, but you should definitely keep that fact in your mind before deciding.

If you throw like TJ you can drill like TJ to TAME the backend and push further downlane. If you don't throw like TJ dont use his layout.

Post by: Kinalyx on March 08, 2007, 10:53:03 AM: My first TNV is a TJ layout. While i dont throw the ball like TJ, i DID know that this was not going to be a big hooking ball, & that it was going to have a more mild backend compared to other TNV drills.

With that being said, my TNV covers quite a few boards, but it has to hit dry b4 it even starts to get into a roll for me, & i have a decent amount of hand. As far as a TNV with TONS of snap, i think drilling #1 is probably the best without knowing your game.

BTW, ive got a 2nd TNV at the shop right now, it will be drilling #1 with a stronger MB.

Post by: urbanshaft on March 08, 2007, 08:36:23 PM: so i went to my driler to drill this thing today.and we were shocked the mb on this ball was so far right he told me that no drilling would work(left handed).but i said think of something and so he drilled it kinda like the jason couche drilling(i dont have high revs either)and my mb is right by my thumb and the cg is hella way up to the left.the ball gos long and snaps but doesnt hook nearly enouph as hopeing.first ebonite ball and its ruined

Post by: Greg T on March 08, 2007, 09:01:19 PM: Time to get a new driller. Any MB/CG position can be drilled very effectively. It's the mass bias you're concerned with and not the CG. The CG is off line. Not the MB. If the cg is off line to left you may need a weight hole to compensate. If it's off to the right it will be in your palm. Whats the problem? If your driller is telling you the MB is off line, fire him and find someone who knows about today's equipment. And the reason the ball doesnt hook is becuae he put the layout on it the Ebo says right in the drill sheet NOT to use. The guy owes you a ball.

Post by: urbanshaft on March 08, 2007, 09:56:40 PM: the mb was 4+ inches to the right of my cg atleast (befored drilled).and if we wanted to have the mb at 40-70 deg then the cg woulda had to of been above my fingers.would that still have worked?he told me this was 1 of those balls u throw away since the mb was so messed up
Title: Re: which layout for most backend on tnv?
Post by: Kinalyx on March 08, 2007, 10:54:24 PM: 2 things he could have done

1, drill it the way u wanted it drill, & add a massive weight hole if needed

2, since the CG is way off to the left, thats perfect for a really strong drilling for a right handed bowler, he could have swapped balls with you & given u a better placed CG for your drill pattern.

Basically, hes a moron, id be pissed off

Post by: CoachJim on March 09, 2007, 03:37:53 AM: In the drilling instructions it tells you how to drill these balls with the cg off line like that. It says drill the finger holes deeper (if the cg is above the midline and the thumb deeper if it is below). Then drill the weight hole where the drilling instructions call for it for what ever layout you use.

You could and should have sent it back, Buddies has always been good about taking back anything the customer is not happy with.

Post by: Cobalt Bomb on March 09, 2007, 04:57:11 AM: Next time, if you get a ball like that, offer to trade it here, or sell it on e-bay, with a pic of the pin-cg-mb. Ones with an alignment like that always get more money, because RH bowlers dont have to use a weight hole for most drillings. I know I have TNV's with cgs good for LH bowlers I would gladly have traded.

Post by: Bigmike on March 09, 2007, 01:45:56 PM: If the top was reasonably low on the ball,he could have shifted the ball for a lefty too. Then he could have put a weight hole out towards the axis near the CG. Here is my awful attempt at artwork.

Post by: Cobalt Bomb on March 09, 2007, 02:46:30 PM: The question is not "can it be done" of course it can. What is preferable is the question. I nor any reasonable person, has a problem with drilling an x-hole in a ball to make it legal. But when the ball has a cg going in the wrong direction over 1/2 ", it makes a real difference in the size hole necessary. Compounding matters is the very thin coverstock shell on today's balls, and the "fluff" surrounding the core has very little weight, causing you to have to drill into the core to get any significant weight out, and the way today's balls flare limits the places you can safely locate that big hole.
I would rather change as little as possible the dynamics of a core that someone much smarter than me designed.
What is necessary is for ball companies to start marking the boxes cg left or cg right if the cg is out of line more than say, 1/2", or for them to get closer to getting them all in line. They already mark the pin placement, but it took them 10 years to start doing that.

Post by: urbanshaft on March 09, 2007, 03:54:35 PM: he did dril both fingers deeper cuz of the weight.and theres a balance hole cuting into 50% of the cg mark.i just hope this ball hooks more then i think it does or i gota another light oil ball
Title: Re: which layout for most backend on tnv?
Post by: Bigmike on March 09, 2007, 03:58:17 PM: You mean to tell me that you haven't even thrown the ball yet? okay, sorry I interjected on this thread.
Title: Re: which layout for most backend on tnv?
Post by: urbanshaft on March 09, 2007, 04:24:10 PM: i did throw it.but the lanes were acting weird i think there was some carry down

Agree... read the drill sheet completely, its noted there.

Post by: jnobcrew on March 10, 2007, 09:09:36 AM: Here's my layout, and it is great for me. I have a little more ball speed than average, so we went with a short pin under the ring finger, 2 1/2 " from CG, and the MB kicked out about 3 or 3 1/2 from thumb. No balance hole. It revs up nicely in the mid-lane, then really turns hard off of the dry. Hopefully my artwork does this justice.
