to be honest i like the teaching JR Raymond best. ultra transparent and honest

Loved part one, thanks for part 2 and all the time and effort you put in. Cheers from Down under

Great video JR! I love the other gentleman joining and giving his two cents worth! Lol

Very much looking forward to part 3

This video series has the potential to be the best videos you've ever done. 👍

Thanks JR, I'm more confused now than I was before ! BTW your little boy is a hoot, enjoy him, while he's little , they grow up very fast! God bless!

Cool vid. Really surprised how much cg took effect regardless of the ball speed

I would like to see you do this with the palm down simulating coming off your hand

JR, The ball at 8:12 is curving because the core is in a strong position at release. Watch the pin as it rolls down the lane; you can see the ball precessing as the core moves into a stable roll and then it flips as soon as it hits the dry. Conversely when you flip it around the core is in a more stable position and doesn’t flare as much. Once again watch the pin.

Odd you wouldn’t think it would make that much of a difference on a symmetric core

Just like I already said earlier, the layout matters ;) The speed has to be correlated with the revs, so if you've 400 rpm, the speed has to be over 20mp/h to overcome the reaction phase.

Is there going to be a future series about pin placement? I thought this video was going to show the UNDRILLED ball rolling down the lane with: 1) Pin pointed at the ceiling, 90 degrees 2) pin pointed towards the side, 0 degrees 3) pin pointed between the two, 45 degrees We know that the results would be, but it would still be interesting to see at slow speed like this CG demonstration.

I'd like to see you throw four balls, all with same pin locations, but CG at north, east, sound, and west. I think that revs, ball speed, axis tilt, and axis rotation will play a much bigger role (pun intended) on effects of the CG. Also, could you stick these two balls into one of those ball spinner machines that finds the ball's psa? I'd be curious if both balls have the same axis migration.

Next test: Drill two balls based on "your" pap. Put your favorite layout on them. But, locate the CG on opposite sides again. Align the balls on the ramp so they roll down "over your ball track." In this way the full dynamics of the core and layout come into play but you are now seeing if the CG location helps or hurts the layout by being on opposite sides. My guess is putting the CG on the side where it will help the ball drive left will make a big difference and will still make a difference at any ball speed. At slow speed the CG combined with the layout will drive the ball quickly into the left gutter, but at normal speeds will give you more drive through the rack.

Great video. This question besides speed is pin placement for bowler

Is Part 3 out?

throw the ball

CG matters, if you want your ball to pass inspection. 😆

Throw them under hand. You’re a pro, you can keep the ball rolling straight and control the speed

Cool video talk Brunswick igniter soild realaitvy soild more strike and spares at time

At a certain speed nothing matters, so we have to put that into consideration. We also have to put into consideration how much of a difference matters. We are talking 0.2-0.3 boards at the pins at 17-20mph and probably 0.3-0.5 at 14mph. So does it matter, 100%. Is anyone gaining a real advantage over someone else gaining 0.2-0.5 boards when you are hooking the ball across the lane, probably not. If it changed the consistency of the balls dynamics, then it would be on the manufacturers to make them closer to spec. In the end the difference isn't enough to really worry about

I'm gonna take a guess and say it stops mattering at about 15mph and doesn't make a difference above that. Starting at 15mph and slowing it down more and more, the greater the difference. Just my guess though

Found this video to be a little annoying with all the interuptions

A ramp to make the ball travel faster is not going to help you. The ball will have to travel down a longer slope to achieve a higher speed so the two balls would not travel the same distance. Plus the 2 balls at any speed would do the same thing demonstrated while in a roll. If thrown by someone the ball will be skidding so completely different.

Just ask Alex Hoskins……..

JR have u tested the ball called payback by Andrew Anderson he said it a ball that gonna aloud u to play stright right on the 3 arrow for a long time amd not over hook on u when the oil pattern gets real heavy

Can't you throw them about 10 mph up 10 and see that they do?

Wouldn't it be wild if you determined that CG doesn't matter around 17.5 -18.0 MPH? So it would matter for about half of your customer bowlers but not the others. 😂

kris prather did the same test with a 900 global ball he bowled a game with it and shot 220 with it. maybe u should do the same thing

Actually throw them the ramp is stupid any ball will hook when thrown slow

Too many tiny variations possible in the way you're testing. Especially at slow speeds. Just throw those two balls 6-8 tones each at varying speeds
