Half Thumb

Hi all. I am wanting to try a half thumb drilling, ala Tom Smallwood. I've been wanting to give this a try for a very long time (probably about 30 years), but I have yet to find a PSO who was willing to attempt this. As I now drill my own equipment, I have the luxury of trying it myself. The layouts...

Varying Pitches

Wondering if any of you have heard of this or done this. Have any of you ever had two balls with different pitches in order to produce different rolls. I have a bowler who gets a huge amount of side turn. I altered her pitches in order to raise her track and give her more forward. Worked great, but ...

Re: Dual Angle Ratios

Wait... I see it. Because the ratio is 1:X, to raise it, I have to add .5 to a NEGATIVE, which would be subtracting from a POSITIVE. I finally remember my 8th grade math.

Re: Dual Angle Ratios

Hi Eric, Thanks for the reply. I must be doing something wrong with the math. Here's what I'm doing for a control layout, according to the Wiki: "For a control layout, you would add the 20º and subtract the 0.5 ratio." 80*+20*= 100* 100*/1:2... subtract .5, so 100*/1:1.5 (1.5+1)=2.5 100*/2...

Dual Angle Ratios

Hi. I went to Mo's last conference at Innovative back in 2019. He did a performance fit for me (which I really like) and passed out the list of his 9 recommended layouts. I have a high axis tilt (30*) and am finding that most of the layouts get me to the pocket, but carry poorly (lots of corner pins...

Vise CS Hybrid vs. Vise Rapid Cure

I've been doing plug work for a while, using Master Kwik Plug. I drill mostly for myself and like to experiment with quick changes to pitches or layouts, so how the ball looked really didn't matter much. I've been starting to experiment with color matching, something that Kwik Plug is terrible at, s...

Over Rolled Full Roller?

Kid who I coach and for whom I drill has an odd track that I haven't seen before. Might be an over rolled full roller. He's a righty who tracks the ball between the fingers (sometimes over the ring finger) and to the RIGHT of the Thumb. His PAP is 5 5/8 over and 3/16 up. Axis tilt is O, though it mi...

Re: 3 Similar Balls Drilled the Same, React Differently

Interesting......I have a question. Tell me your resurfacing procedure. Which ball was 1st? Did you start w/ a fresh pad? Did you use the same pads for all 3? Jackal, Bite, Growl, in that order. Fresh pads, used the same for all three. Put them on the ball spinner, 15 seconds 4 sides with the 360 w...

Re: 3 Similar Balls Drilled the Same, React Differently

Definitely the coverstock, but now you know so you can make adjustments to the covers so you can have different looks That's what I thought, too. The Jackal is my "go to" ball when there is any kind of significant oil. I've tried different surface preps with the other balls... all the way...

Thought about that. The core shapes are fairly similar, asymmetric bulb-type shapes. You could be right about the cover stock formulas, though the difference was pretty stark.

3 Similar Balls Drilled the Same, React Differently

As an experiment, I drilled 3 balls, all of which are very similar, identically. Got very different reactions and I'm not sure why. Here are the three balls chosen with their specs. All are 15 lbs: Motive Jackal Ghost RG/Diff: 2.47/.54 DV8 Pitbull Bite RG/Diff: 2.48/.055 DV8 Pitbull Growl RG/Diff: 2...

New USBC Specs

With the new USBC specs being legal to be used in less than a week, I'm wondering how to drill to them. For example, if I want a ball with 3 oz. of side weight, how do I measure that out so I can attain it? I've been using the double angle method, but my guess is that will needs some adjusting to at...

Re: 14 pounds vs. 15 pounds

15 mph is a bit slow for college bowling, I would go to maybe a 13 lbs and work on cross training and conditioning while she works her way up to 15 lbs. College female bowlers: 15-17 mph monitor speed at will, 300-375 rpms at will, 20-45-60 axis tilts at will, loft from 6” to 8’ at will. In other w...

Re: 14 pounds vs. 15 pounds

A top college program will have strength and conditioning for their athletes. She is still young and barring any injury should be able to gain more strength and the ability to control the heavier ball. Force =Mass x Acceleration 210=14 pounds x 15 mph 202=15 pounds x 13.5 mph By the numbers the 14 ...

14 pounds vs. 15 pounds

Girl I work with throws 15 pounds. She's very good, averages right around 200. She struggles whenever there's a bit of backend, and typically has to play as far left as she can on nearly all conditions. Problem seems to be her speed, which is around 13.5. As the night wears on, she also has a tenden...

Re: Low Flare Layout Advice

On a strong asymmetrical ball, I would consider Mo's short pin layout. here is the video: As far as the finish, do not use skip a grit. Go through all the grits you can and finish with a worn out 4000 at least. skip a grit can be snappy. Going through all grits is more controllable. [youtube]https:...

Asymmetrical ball 65-3-65 Thanks for responding, Eric. A few questions: 1) I'm curious... Ive always thought that because of her Rev Dominance, a wea...

Low Flare Layout Advice

Looking to drill a low flare ball for a girl I coach. She is very Rev dominant with a speed of around 14 off her hand, high axis tilt, slightly high axis rotation. With this combination, pretty much everything I've drilled for her is Control, often with a P1 hole. She gets the ball down the lane pre...
