Hi Guys,
I recently bought a NIB heavy top weight ball which was going cheap. the ball came with a 1'pin, and 7 1/2 oz of top weight, Im not too worried about what type of ball reaction i will get, as the cover on this ball is super strong.
But I would like to hear any layout suggestions, the drillers on here have.
-
what type of ball? asymmetric vs symmetric is a big deal. Also, bowler's stats and conditions would be very helpful

Is it an AMF or Global 900 ball that say for display only?
You need to remove 4.5 ozs of top weight which is a lot.
I would suggest putting the cg near the middle of your center grip line and a little towards the positive side of the ball. (to the right if right handed) I would try using a scale first and draw your lines and weigh the ball for side weight first. I''''m not sure how much side weight you would have if you moved the pin 1" right. You may have to go less like 1/2".
The ideal goal is distributing some of the top weight to the side so there is less to shoot for drilling out the fingers and thumb. Plus you can place the weight hole as to increase performance ect ect ect.
On any ball where I think it may be close on weight for something I draw the lines and then weight it like it was already drilled and see if it will be close for say needing a weight hole usually.
I would try for 2 to 2.5 ozs side weight. (Before drilling.) That way it takes away from the top weight some. Then I would weigh it for top weight and see how it is looking so far.
Depending on what the scale said so far I would drill the ball up and go ahead and make the thumb and fingers a little deeper then usual. Then check the side weight and drill your weight hole.
The goal is to move distribute some of the 7.5 ozs off to the side so you can easily take out the rest of the needed weight in the fingers and thumb as needed to get the ball to 3ozs or less on top weight.
Hope it works

Thanks Kid Lost,
Yep it is indeed one of the For Display Only Balls, Got a few of them in to mess around with, I will try to get it drilled, Someone suggested previously that id have to put a weight hole above my finger tips?
I still dont get why they feel the need to ingrave -FDO into the surface of the ball if the only defect is a high top weight LOL
-
Depending on where the cg is located has an impact on where the weight hole may need to go.
With the one you mention having a really short pin if you moved the pin up the cg follows and then you have some big problems with having a lot of finger weight and trying to remove it. Which would result in needing an extra hole near the fingers in that case.
The main problem with the ball is because of the high top weight you really need to keep the cg very central to the middle of your grip so as to easily remove the weight and not have too much go to the fingers thumb or one side or the other of the ball.
Plus many of the ones I have seen have 8ozs or more top weight. That is a lot of ball to remove.
If you have any with longer pins do the same thing with the cg and move the pin to more desired locations like usual. I wouldn't worry about the MB ending location. With the top weight being so high the cg is priority one then the static weight, and then the pin placement.

If the top weight is correct I don't see any way you can drill that ball so the ending static weights are legal. -- JohnP

I think they label them with FDO because thats about all the ball is good for with that kind of TW, lol. They have to label it with something, whether it's X-Out, or Blem, or whatever, otherwise someone could ditch the box and say its a 1st quality ball and sell it for a higher price. Nobody would know until a shop put it on a scale.
Good luck!
-
aside from the actual topic, i think a ball labeled "for display only" might not be legal in sanction play. the only reason i say that is because earlier this season, ebonite intl. had balls marked "test ball". i had found out later that the usbc had said those are not legal to use. i can't say for a fact, but that's what i was told from genarally a reliable source.
-
900 Global labels the balls FDO beacuse they are sold to pro shops etc at extremely reduced prices so they can get their product in the public's eye without the pro shop having to pay full price for a display ball.
If you really must try to drill the ball you may need to place the weighthole in the middle of your grip to eliminate the extra top wt.
I had an original black Hammer with 5-1/4 oz top wt that made legal by putting a hole in the middle of my grip.

Weight hole should go into the cg. That is where the top weight is located on undrilled balls. If you kick out the CG, all you are doing is making the side weight very high and probably not removable. Only guess I could make is drill the thumb into the CG and go as deep as you can with the thumb hole.
Basically, I think it would be impossible to make this ball legal.
-
FDO are not leag anyways so Drill it what ever and use it in pot games lol
or non sanction play

I am not too worried about the layout in relation to ball reaction, More just to make the weights legal.
To be honest a X-hole in the centre grip would be fine, As i see all sorts of patterns im sure ill find a use for it, the balls to my knowledge are USBC approved and are legal in competition once the top weight is removed to meet the requirements. for example some of the balls came with 4'' pins, and 4oz top weight, and was marked FDO, again at a very reduced price!
-
Was checking online and they don't have it on the not approved ball list yet.
The other thing to consider is the ball itself is USBC approved in name and design the main reason they are marked for display purposes as mentioned is the high top weight.
That being said if the ball weights are made legal then until USBC enacts a rule saying other wise it should be legal for USBC use.
Also on the banned list the last ball listed is a Dynamo. I can only think of one and that is by Lane 1. It doesn't list manufactures on the list. Does anybody know anything about that? (just curious)

Dynamo needs 45 boards of play area and since there are not 45 boards on a lane then the ball is deemed illegal...
As far as drilling the FDO ball, do as someone suggested earlier and just use it for pot games.. Put all 7 oz on positive side and see if CGnomaddah
(was a joke) 
-
I looked at three of these 900 Global balls in the shop tonight and they are marked USBC approved and have all other markings like any first quality 900 Global ball.
The main point is for display only and not to be resold for bigger profits. If you get the weights right you are good to go.
