Drilling a Blue Gryphon
« on: June 09, 2003, 08:50:55 PM »
Have a 16lb Blue Gryphon, 2-2.5oz top weight, 2-3" pin.  Visionary
doesn't have the drilling instructions up.  I want the ball to have
length with a hard arc to the pocket, not the hockey stick move of
a 3 3/8" drilling.  What drilling would anyone suggest?

Thanks

You could email Visionary and ask them or ask them to send you a copy of the drill sheet.  Wasnt there a drill sheet in the box?

I dont understand length with a hard arc?  My definition of an 'arc' would be what we used to call a curve, that is, something that starts to move early and continous.  If you get significant length, then it hooks, it will be more of a hockey stick pattern, wouldnt it?

MI2AZ, I was thinking the same thing.....isn't a 3 3/8x 3 3/8 THE arc drilling, most overall thru out the lane?

I am not a driller nor am I up on all of the drillng theories, but I thought that a 3-3/8 leverage drill was the strongest combination of length and hook.  So if you place the pin to get more length, dont you lose some hook in the process?  Maybe he means by hard arc a 1:30 leverage drilling?

Asaturno, let me check tonight when I get home and see if I have a drill sheet for the Blue Gryphon.  I dont remember if I kept it or if I left it at the proshop that drilled mine.

I would suggest putting the pin next to the ring and slightly up and placing the cg in your grip center.

I guess I was assuming that the 3 3/8" drilling produced
a strong snap reaction....I wanted a little less of that snap;
more arcish but still strong.

I wanted a ball for Length and med arc. I have some hand so this may be a little more extreme that a 4x3. I place my pin under the ring finger and had the cg kicked out towards the pap. I didn't put in above the fingers because I wanted a better midlane read on lighter oil lanes.

This layout gives me length and a nice late arc of the dry. if the lanes are a little dry with a touch of some head oil it will arc the whole way.


On more oil it gets a little more hockey stick shape but still controllable.


stay away from stacked drilling and high pin placement you will be ok. I find Visionary balls are drill friendly and normal drill patterns apply very well to them. I would not be so concern about a drill sheet. It's not a fancy asymmetrical core like a freak or warrior. all MB layouts should work. Consult your driller. or check out this info. http://www.rollrite.co.uk/secrets/

Ok Omega, I've been reading that site and I
think I get it.  How does this sound...

Pin to PAP of 4" with pin just under the
ring finger.  MB located at 45 degrees.

He doesn't mention CG that much...how important
is it?

Thanks.

CG importance has been a heavely debated topic on past threads.

I gather it to be like this.

on strong Mass Bias ball the cg is third in importance. the pin and MB are the main placement indicators. the cg is a further tunning tool.

on balls with little to no mab the MB is the third or fourth tuning tool.On balls or this type, the shell is the major factor in the ball reaction.

MB is a more precise method of tuning compared to the CG. If you use the MB, you do not use the CG, as far as I have learned. In fact, very often, on balls with a marked mass bias, the CG is not in line with the pin and the MB, therefore using it can through off the entire "tuning" process. On symmetrically designed cores, the MB is commonly located by measuring 6.75" from pin along a line through the CG. On balls with a marked MB, the CG is ignored completely until you measure to see if a weight hole is needed to make the ball ABC legal.

asaturno,

The common stacked leverage drilling, 3 3/8" x 3 3/8", (pin and CG from PAP), is for any one ball the most middling drilling FROM THE POINT OF VIEW of length (it's not the longest and it's not the shortest) and the greatest one for overall flare (which usually relates directly to the most overall hook).

Pearls and polished solids can be flippy with this drilling, but it's the ball not the drilling. DUll solids and particles will ALMOST never be flippy with this drilling, but, again, it's the ball, not the drilling.

The Gryphon is a highly polished solid that goes very long naturally because of the cover and the core. Visionary says it is not skid/flip, but I assume with certain drillings in combination with certain types of releases and certain oil patterns, this ball can appear to be skid/flip in its reaction.

Drilling patterns, with the pin below the bridge that may help you make sthis balls arc are 10:30 types: 5x3, 3x1, 4x2, and 1:30 type of drillings: 3x5, 2x4.
A lot depends on your hand (release) and the oil pattern on which you'll use it.

GOod luck.
