Frankenball - reuse, recycle?

So, I'm watching bowling one day and my daughter asks me "Dad, have you ever made a bowling ball?" Answer, "No, but I've thought about it". Now I have, kinda. cracked-iq-tour.jpg dovetail-2.jpg dovetail-3.jpg quadrants.jpg sliding-dovetail.jpg Given the long break from bowling, Covid downtime, and l...

Re: Kegel Specto Lidar

A friend suggested using a video camera and OpenCV. I never had much luck with TrackMyRoll, but he seemed to think that image processing might be the way to go. I don't know that API, but it appears quite capable - just a thought...

Re: Kegel Specto Lidar

Jarek, I was wondering if you discovered anything interesting re: LIDAR? I visited Kegel a few years ago and felt like it could be possible to "roll your own" lite version of Specto, but I never got around to doing it. I'm talking bare bones, nothing as polished and feature rich as Specto. At the ti...

Re: Copying a Switch Grip with unknown specs

I'd suggest you just find a qualified, experienced pro shop... I do know that can be difficult, so here are a couple of ideas. Vise and Turbo recommend drilling the pitches into the ball to accept their permanent inserts. The hole in the removable slug is neutral, ie. no pitches. The hole should loo...

Re: Conspiracy Layout

The layout you describe on your Idol is in my estimation a fine layout for your estimations. The Idol is a weaker light oil coverstock. You want more hook get a stronger ball. Your choice of line could be to blame. 5 board on a house shot is considered to be a high friction line playing in the dirt...

Re: Pin to pap symmetrical ball only, curiosity, non 2 finge

GG does still matter for making the static weight limits. Right now, we can choose the 1 oz finger/thumb/side with balance hole, or the 8/1/2020 3 oz finger/thumb/side. It's 3 oz top/bottom regardless. There's been ongoing debate, simulation and testing as far as what difference 3 oz of finger/thumb...

Re: Completely Lost With Layouts...

Rolling over the fingers is definitely not the end of the world. Some layouts will do that for me, and I have a thumbless teammate who always tracks over the fingers. Rolling over the thumb has been a real reaction killer for me, tho. What type of ball do you have the full roller on? Is it a low fla...

Re: Completely Lost With Layouts...

I can sympathize with your frustrations. I also track high, and have been working on adding tilt and moving my track away from fingers and thumb. It's been fairly successful through practice, getting physically stronger, experimenting with span/pitches. My experience is that with your low tilt (and ...

Re: PBA Playoffs. HATE the shouting.

Having just spent the day up in Portland to watch the playoffs, I'd have to say that TV doesn't really do it justice. The costumes, the yelling - yes, it's not traditional. It's silly, fun and entertaining! Some of the chants and nicknames are pretty clever and the players do enjoy it. Those are som...

Thumbless bowler, general layout advice

Mo posted a new video a while back, which builds on what he has published previously.

Re: Turbo switch grip drilling depth

Thanks again, I do appreciate it. The installation guide - "Pitches: Desired pitch should be set and drilled when installing Outer Sleeve. Inner Sleeve should be drilled at same pitch." That seems to make the most sense to me, although I can imagine scenarios (like you mention) where you change pitc...

Re: Turbo switch grip drilling depth

Ok, another quick question.

How common is it for PSOs to drill the outer sleeve with 0,0 pitch and then do the thumb pitches on the insert? My sample set is small, but I've seen it done both ways.

Thanks again,

Steve

Re: Turbo switch grip drilling depth

Thank you! That's really helpful. I didn't notice the depth indicator on my outer sleeves (some had it, some didn't seem to) but the measurements worked out. What confused me a bit was that I measured 2 balls from 2 different PSOs and the depths were different. So, it makes sense that people might a...

Re: Turbo switch grip drilling depth

Alternately, can somebody put a ruler/caliper on their bit and tell me the distance between the stop and the outside corner of the bit? turbo-drill-bit.jpg.jpg Using the diff between the inner and outer slug, I came up with a range from 2.78" (2 25/32") to 2.813" (2 13/16"), but I think that's too s...

Re: Turbo switch grip drilling depth

Old thread, slightly different question. When you install the outer sleeve in the ball, how much protrudes above the surface of the ball? I don't have the "Turbo certified drill bit", but do have a 1.5" bit with a stop collar from McMaster. Working from an existing thumb insert (I borrowed one from ...

Re: The core hitting the pocket...

MathIsTruth confirms the RG of the PAP remaining constant in the thread elgavachon linked to. From post 52 in that thread, "The spin axis will migrate and maintain an RG value which is equal to the RG value of the original PAP." Right. I understand that particular test is not within spec and that t...

Re: The core hitting the pocket...

Thank you. Glad to see that my personal observations are consistent with what Mo and MathIsTruth have documented in the thread. It might take a high diff core and particular release characteristics, but there are conditions where the elliptical axis migration path moves the pin towards the axis, and...

Re: The core hitting the pocket...

That looks like a lower-flaring control layout on a higher RG sym, medium-high diff (2.56/.047). Can you run a Black/Blue Paradox, OOB at 60x4x40 with my sig specs. Span is 4.875", typical finger pitches, thumb 1" left and 3/8" reverse pitch (ADT). Add a double thumb or P3.5. Always curious. Thanks!...

Re: The core hitting the pocket...

I may have over-stated that it "settles into a lower energy/RG position". I was attempting to paraphrase the direct quote from the article. "The test ball loses energy and migrates toward a lower energy and lower RG values." I can see what you're saying from the simulation. I'm not trying to split h...
