looking for suggestions for a 9inch pin dyno-thane dynosaur pearl
-
If the pin is 9 inches, cant you just use the other side of the ball and it will be less than 9 inches?

Yup. Draw a line 13.5" from the pin through the CG and call that the "pin". Drill it like a 4.5" pin ball using the new "pin".

is the spot use get at 13.5 the center of gravity or the pin

To use a 9 inch pin...one would have to get with 9andawiggle or other such 9 numbered users and see one must deal with to handle 9!

I have an Element AU79 drilled with a pin basically on the other side of the ball as the cg...
Driller just would up pretty much flipping the core...you can tell cuz you can see the top of the core thru the finger holes. Funny thing is DynoThane just came out with a new Element with, guess what?
An inverted core...
Hmmmm.... maybe blems aren't always bad.

Ali G : A lot of boys me know are trying to get their girlfriend to try a bit of feminism, do you think that if right?
Sue : Yeah I do actually I think it's a good thing.
Ali G: Do you think all girls should try feminism at least once? Do you think it's right that they should try it when they is drunk at a party or what ever with one of their mates?
Sue : What is trying feminism?
Ali G: You know try a bit of feminism and when they is sober wake up in the morning and get back with their boyfriend?

A lot of designs are just the same core flipped.
My understanding is when the flip block ends up on the bottom that the ball is flippier than when on top!
However in picturing this situation...doesn't one need to be aware of top weight!
Or am I not picturing this situation correctly?

Lucky...if you draw the 13.5" pin on the ball it will end up being only 4.5" from the actual CG, so there shouldn't be any issues with static weights.
I have never personally tried this out...but it sounds like it should work.

Well I assumed my driller did all the measuring and stuff to make sure the ball is within legal limits.
I think you're right about the ball being flippier..the AU79 is supposed to have a fairly angular backend but be farily earl getting into it. Mine takes off hard, but pretty late.
The new element also takes off later and harder (granted it also has a different coverstock) but that would seem to bear out what you've heard.

I would weigh the ball and make sure the CG is not mismarked.

Yeah, with any "blem" for other ball for that matter, its always good to weigh the ball first to determine if the cg is acurrately marked. Lane#1 website has a good explaination of this process: http://lane1bowling.com/tech/cg.html
If the cg is accurately marked, then drawing a line 13.5" from the pin through the cg will give you the exact bottom of the core, in essence flipping the core upside down. Depending on the shape and densities of the core, this could have little or a fairly pronounced effect on reaction. But with a blem, its pretty much the best method for drilling them up. Lay the ball out with the "new" pin and original cg just as you would an other 4.5" pin out balls. I know many people who have and love equipment layed out this way. Its a great opportunity to get decent equipment at a fraction of the cost.

I'd rather have a 9" pin than a 6-7" pin
