Title: 3 3/8 Stacked Leverage, Dual angle qurestion.
Post by: mfhames on December 02, 2010, 11:34:36 PM

Using the dual angle drilling method, what are two good angles to use for the drilling angle & angle to VAL in order to get the pin and cg stacked directly above and below each other on the VAL line?  

Drilling a Storm Invasion and the pin measurement is 3 3/38.

Thanks in advance.
Mike

It will depend on the lineup of the pin/cg/mb and your pin distance to pap in relation to your angles.

The cg is not the concern in the dual angle method other then static weights and weight hole locations. It is about the pin and mb placement.

If your concern is on the pin and cg placement lay the ball out how you want it to be, then measure the angles afterwards.

Likely 45-55 X 4" X 30 will be close.

+1 To kidlost.

But also, I believe alot depends on your vertical dimension for your PAP. If you are like 4 1/2" over with no up/down..then 45 x 3 3/8 x 45 would be stacked. if you have a up/down dimension, then the angles will have to tweaked accordingly to get the stacked layout....IMHO....Basically everything Kid said...lol!

i think 65 X 3-3/8 X 25 should be pretty close

If you know what you want the layout to look like, why bother with double angle?  Draw the VAL through the pin and cg, locate the PAP by marking the spot on the line that's 3 3/8" from the pin, draw midline, grip center, and centerline and you've got your layout   The double angle system is used to best match the layout with the customer's game and desired reaction.  You've already determined those aspects.  --  JohnP
