The Phantom series had two different core designs. The Light Blue and Black had something close to a light bulb with a ring around it, the Crimson block looked almost like a mallet. The locater pin on the crimson is on the axis side of the ball so that the ball would be drilled with that locater directly on the axis point. The Crimson was supposed to be the longest of the three and by placing the locator pin on the axis, it made the ball roll very smooth on the conditions we played on back then. To lay out the ball, you would start at the locator pin and measure back from the axis to determine the starting center of grip.
The locator pin on the other two Phantoms were to help with tweaking the ball's reaction and flare potential. This stuff was way ahead of it's time and Brunswick put out a video to help with the concept and grasping the terms.
If you drilled a Quantum Stripe (the one with the urethane strip, gold and fire) you had to lay the ball out the same way so your track would start on the urethane part of the ball, then flare onto the reactive part of the cover.
There was another ball back in the day called the JPF Axe that had to be layed out the same way to maximize the roll potential the manufacturer had in mind when they created the ball.
If you have the PDF drilling specs in a file, it would be nice to look them over once for informational purposes. Could you PM with a link or e-mail address? Thanks
