Title: Could this be a way around the diff. limit ?
Post by: 302efi on July 02, 2008, 04:37:07 PM
The USBC rule now is .060 max differental.

What if the manufacturers would put a drilling sheet with the balls that would mark the exact locations to add extra holes (X-Holes) and what the resulting diff would be ?

They could include the bit size and dept ect...

Something along the lines of:

If X-hole is placed "here", the differential would be "XYZ" ?

Mo Pinel has pretty much done what you speak of.

I found this to be very interesting, as I have a storm vertigo that has around 6-6 1/2 inches of flare, so basically my vertigo is almost not legal then..hehe! It has a 4 1/2 inch pin to my pap and a small 5/8 hole 5 1/2 from the center of grip 1 inch below midline 3 1/4 inches deep. This ball flares too much..lol
Another question is, is the max diff after drilling or before it? Because if it is after, then i am in trouble on two of my balls....I am border line.

The RG and RG-diff are for an undrilled ball.  Or, even if they drill it in some standard way, once they declare that the diff is, say, 0.050", and the ball is approved, it makes no difference what the final drilled diff is.

Considering that most shops don't have the equipment needed to measure the diff, requiring a certain max diff on a drilled ball seems silly.

How much flare do you really need?

When they first announced the rule, I remember Ron Hickland (Hammer/Ebonite Tech Wizard) coming on here saying they were working on developing drillings and such to get around the rule.  I don't know as they have come out and said "By placing a hole at this spot the differential increases by X"

Shelley is absolutely right, all of those measurements are on pre-drilled balls and they have to be uniform across the board.  There are layouts you can use to increase and decrease RG and RG-Diff, so as long as the ball STARTS legal, it could feasibly be drilled, and, as long as statics are within USBC specifications, it could techinally have an illegal RG/RG-Diff.

Unless you had something like a lightbulb core wouldn't you have to put a secondary pin in every symmetrical ball so that you would know exactly how the core was oriented? It seems like you would also need separate drilling instructions for every core shape. This would cost the company money and really, who besides the people on here, gets into this stuff? Plus, the good drillers already know how to manipulate the layout to make their customers happy.
