Title: Rico on a ball with a marked mass bias?
Post by: Fatboy8 on February 11, 2007, 12:37:16 AM
I was wondering how you go about laying out a ball, such as a: Vapor, Red, or Strike Zone, with a Rico drilling. How do you factor the mass bias marking into it.

Thanks!

skip the cg and use the mb to lay it out  IE place the mb 45* to the pin x hole as close to 3.375 from your pap on the line between the pin and mb

So the MB would still be between the weight hole and pin, if you draw a line through them? Thanks Trigg!

If I am not mistaken, you would lay it out the same as a symetric core and drill the weight hole through the mb which is 6-3/4 from the pin through the cg.

That's what I was wondering too. If you'd be drilling right into the mass bias.

see this info is not entirely correct, a "true" rico is with the hole 3.375 from you pap on the line that is drawn at 45* to your pin.
Fatboy, talk to Bracketcreep about this.  he and i had a couple of discussions about this, the 3.375 is the reason you see the hole in different spots for different people

So you're saying Ric Hamlin himself is wrong?

I am saying a true rico is 3.375 on the 45* line from pap, a rico II is the 6.75

the "rico" drill has been around for a long time, Ric hamlin did not invent that, he popularized it on the tour.  that drill has been used for a number of years on ebo and hammer stuff, as well as others.  Fatbow, once again talk to BC he will shed some light on what i am talking about

I may be mistaken, but I thought I remember reading that for asymmetrical core balls (with a pre-marked mass bias), the Rico layout was the pin/mb line at 45 degrees from the center line, BUT the weight hole was placed at 3 3/8 from the pin on the pin/mb line (and not at 6 3/4 for symmetrical balls)?  Maybe I was confused, but I thought thats what I had read...

You are right Trig I did not invent the lay out and yes I have been credited with it because of use at certain events.
The way I have used it with asymmetrical core balls is, since the mass bias reacts similar to a weight hole, where the mass bias differential is high enough, I place the weight hole, if necessary, along the pin to mass bias line at the horizontal axis coordinate and have gotten desired results.
Weight holes tend to alter asymmetrical core balls less than symmetrical, so for the most part, weight hole placement in an asymmetrical core ball will have less affect.

No I did not 'invent' this layout but I have used it numerous amounts of times in many different rolls and have had very good success.

Thanks Ric, I was not trying to discredit you at all, hope you did not take it that way.  you deserve credit for putting a fantastic layout in the proper hands to tame those nasty pba condtions, some of the older, seldom used layouts and tweaks of those are great for todays condtions and oil patterns.  My personal favorite is a semi pin axis or tweaks there of
