Classic Zone Static Weight Problem?
« on: April 08, 2006, 05:17:30 AM »
i got this in the mail from bowlingball.com and the specs are:
16.1 Lbs.
4-5.5" Pin
4.4 Top Weight

after opening the package to see the specs, i cringed.
especially after i requested 2-3" Pin 2.2-3.7 Top.

assuming i used 2 finger grips and a big thumbs slug, and x-hole, will static weight be a problem do you think?

anyway, i laid it out, here is what it looks like...

I can't speak to the other statics, but top weight shouldn't be an issue for you unless you have a really tiny hand.  I have a small hand, and I still take out almost 2 1/2 ounces with the gripping holes.

If that's the CG down there by the PSA marker, I think I'd be more upset at the fact that it's kicked so far to the right of the locator line.

i updated the picture with a new layout overnight.

if i used a big thumb slug, i think its close to 1&7/16" bit 3" deep and an x-hole 1&1/8" bit 2.5" deep, thats about 4.7 ounces removed according to this chart...

i wonder if this layout will work, would be interesting.

anyone else?

if you had read my initial post, you would know thats not the subject of this conversation.

im looking to see if static weight is an issue after drilling with the proposed layout.

Thats a tough one....you may have more thumb weight than you can get out....it will be close in my opinion.....

Here's what I would suggest, you said in your initial post that you intend on using a thumb slug.  What I would do is use an 1 3/8 Slug..drill 2 1/2" or whatever depth you usually drill for your slugs, remove the 1 3/8 bit and put your 1 1/4 bit in and bury it (drill as deep as you can with it).  The "step" in the hole where you switched bits down to the 1 1/4 will be sufficient to keep your slug from dropping and the extra weight removed by going an extra 2" or so with the 1 1/4 should give you the ability to remove the additional weight needed with a balance hole in the thumb positive quadrant of the ball.  I'd line it up and weigh it to see exactly what you will need to remove but I think if you go that route you may well be able to get it.  Good Luck!

What I would do, is one, drill the big slug to normal depth.....throw in your weight hole. Drill your fingers as shallow as possible as drilling the fingers deeper is the same as removing finger weight and adding thumb weight... If you can not get enough out after you have the ball done, I would go back to the thumb hole and drill it deeper.....obviously talking about just your thumb hole and not the slug hole.

is there another way i could lay this out to get an aggressive reaction without static weight complications?

i figured that putting the CG down near the thumb hole and x-hole, there would be more weight taken out in that area.

i dont want the PSA on the negative side, thats why im having a hard time getting a decent layout on this.

if the CG was on the other side of the MB/PIN line, there would be less difficulty getting it legal on the scale.

thanks for the replies so far, its giving me ideas to hand over to my ball driller.

Mav,
You could drill the thumbhole into the PSA and place the pin 4" from your PAP. The pin will end up high, but that should increase the backend reaction, if anything. The cg would end up a lot closer to the midline. You could even drill the x-hole into the cg, if necessary.

i had something similar to that initially CK,
with the pin above the bridge and PSA in the thumb, but i think it would travel too long before making a turn for my liking with that MB position.

i have that 4X4 layout on my original inferno, and i love that ball.

so, certainly its an option, thanks.

exactly.

im asking these questions assuming the CG and Top are correct, but when i get it drilled, ill be sure to get everything scaled up.

is there anything i should be wary of? like side weight?

i think those 2 holes (thumb & x-hole) will cover 3.4 ounces easy out of 4.4.
minus the finger holes.

how much does the thumb slug contribute to replacing weight back?

May I suggest one thing, if I read that picture correctly?

Move the pin up higher to the ring finger and put the pin directly under the ring finger, instead of under the ring finger. I've done that a number of times recently. The length change is minimal, it meets Brunswick's requirement about not drilling out part of the pin marker, and it helps reduce/modify your thumb weight problem.

FYI I got balls from bowlingball.com like this also - 5.5" pin-CG. They're what STorm calls "pro pins" - in other words not technically blems, but ones that cause many problems, like this one and severely limit drilling options. And Brunswick says they don't make or sell "blems"? That's debateable.

I just won a Classic from bowlingball.com also.  I would LOVE to get these specs!!!  This ball is ideal for what I want to do.  I also use Switch Grip so with a 1 1/2" hole it helps to take the top weight (thumb weight in this case out).

I would first weigh the ball to make for sure the cG is correctly marked.  I have had 3 Brunswick balls where the cG was not marked correctly (over 1/2 off in each case).  Just something to double check before you begin the layout/drilling.  

I agree with charlest, move the pin up so that it is just under or just above the fingers.  This should put the cG just above or even with your thumb.  Drill the thumb (use 1 1/4 bit on thumb) and fingers (shallow on the fingers as others have said).  Don't put the slug in yet.  Check the weight and see if you are still way over or if it is manageable with a hole.  If it is still too much try going deeper with the 1 1/4 or go to 1 3/8.  

This ball is managable and will give you a nice reaction just have to play with the layout and have the scale handy as you drill.
