It's not his actual thumb, it's a piece of bowling equipment called an 'interchangeable thumb' used to customize the depth shape of the thumb hole on a bowling ball.

It does not change the depth of the thumb hole. It’s used to change the shape and diameter.

Finger and thumb holes are drilled to specific depths and diameters. Most custom balls have both thumb and fingertip inserts, being standardized at about 1” OD which makes it dead-simple: slap a 1” bit in the press and start drilling. Obviously there are rare cases where that’s not big enough, but most thumbs and fingers will fit a 1” hole with room to spare. The inserts are used to fill the space. Fingertip inserts are generally a lot softer than the ball resin/urethane while thumb inserts are harder and smoother plastic for better release.

The inserts are selected for finger fit and can be sanded for more precise fits, and are glued into the holes with CA. They are easily replaced. The CA will eventually fail, which is likely what happened.

"I’ve drilled hundreds of custom bowling balls."

Did you drill it with or without the insert?

Obviously he used his thumb

u/macabremasterplan 8d ago

Of course, if he's rich enough to play competitive bowling ball, he should be able to afford enough spare thumbs

I wish I were good enough for competitive bowling ball 🤷‍♂️

I always wanted to be good at football ball myself

u/LordNightFang 7d ago

Yeah it's tough. At one point I was averaging like 220 per game and I was still put on the lower team cuz my schoolmates would make about 240-270 per game. I felt like a total noob.

u/Scrub_nin 8d ago

New insert every time. Cleanliness is of the utmost importance

u/Jason_Kelces_Thong 8d ago

That’s why I never throw the same bowling ball twice. It’s an expensive hobby when done right

u/worldspawn00 8d ago

Nah I don't want that ball, it's been on the floor. Bring me a fresh one!

u/Super-Magnificent 8d ago

You should probably try drilling women instead. Much more exciting than doing the nasty with some old bowling ball.

u/False_Disaster_1254 8d ago

and your fingers fit perfectly into the holes, every time!

I always love it when someone like you turns up with real life experience and knowledge.

Question about custom bowling ball: Do you need a custom one if you lack fingers, or does a standard one suffice?

18

u/ecafsub 8d ago

Never did one for someone without fingers, but I did do a couple for a guy who wanted only the thumb hole. Balancing it for drilling was a little tricky as you have to account for removed material and not drilling finger holes shifted the center of gravity a bit. Not a lot. A few ounces of urethane out of a 16lb ball isn’t much. Also drilled the thumb hole at a bit steeper angle toward the center so he could hang on moar better.

He had some kind of glove that had a grippy texture on the palm and fingers. Dunno where he got it.

I had my own custom ball as a teenager when I was in a bowling league (bowled a 300 when I was 15, not in league though which sucks, just out with friends. I had them print off the scoresheet and my mom has it framed at her house) and I had those finger inserts put in since they help a lot with curving the ball imo. Never had a thumb one though.

1

u/ecafsub 7d ago

They absolutely do help with that. I’ve never seen anyone bowl a 300, tho I’ve seen someone make a hole-in-one. Good on ya!

u/SOfoundmytrappornacc 7d ago

Yea I had the whole bowling alley come and surround us when I got to the 7th/8th frame lol it was so damn nerve wracking that I was shaking.

I also wasn’t using my ball because I forgot to bring it so I was using my friends custom ball that had those inserts, but they were fitted for a right handed person and I’m left handed. So the middle finger and ring finger inserts were switched for me and felt weird since it was almost too tight for my middle finger and almost too loose for my ring finger.

I had like 50+ people watching me (I still remember everything so vividly lol I’m 33 and was 15 at the time) and since I was bowling with friends everyone had to wait and watch them before my next turns lol

it was so cool how quiet everyone got on my last strike, especially cause the way I curve the ball it always looks like it’s just about to gutter and hovers on the edge for a few seconds before cutting back in. Then the whole place erupted after that last strike. Everybody came up and shook my hand and kept asking how old I was and how I could be the youngest person in Idaho to bowl a 300 ( never actually did find out about that) and the owner came up and shook my hand.

It was seriously one of the greatest moments in my teenage life.

u/logan5_jessica6 7d ago

amazing story!

im shit at bowling, so 15 year old me used to be on a high for days even after getting a strike😝 id have been on god mode if I came remotely close to 300!

well done mate for keeping your nerves in check, not easy..

and thanks for sharing the story! 👍

u/SOfoundmytrappornacc 7d ago

Thanks dude! People don’t believe me when I tell that story and so I only tell it if I’m actually bowling lol since people can see first hand that I’m still very good at it.

The sad thing is that I stopped doing league bowling when I was 16 because it wasn’t “cool” and I cared more about partying and stuff. I definitely could’ve made a career out of it. I had been doing a lot of traveling for tournaments that I had qualified for and I didn’t like that, I wanted to be where my friends were🙄 lol

I went bowling for the first time in a few years a couple months ago and I bowled a 195 and a 211, so I definitely still got it lol but I’m not sure how to get back into leagues and tournaments and stuff.

u/logan5_jessica6 7d ago

think of what you can still do, dont be hard on yourself for things you can’t change..

like, you can acknowledge poor decisions to keep you grounded, but too much regret just weighs you down..

you stopped league bowling perhaps because you had different priorities back then..

you can still find local leagues or just go bowling with family and friends.. or just bowl for the fun of it and go by yourself if you have to.. grown men can have hobbies..

dont give up on what you enjoy!

u/NeuroticNinett 7d ago

Interesting stuff. Thank you!

u/Trappedbirdcage 7d ago

If not doing so competitively, I've been to a few bowling alleys that had ramps where you put the ball at the top and push it down. Mainly used for kids but I've seen disabled and older folks use them too.

u/vahntitrio 8d ago

I would add that the purpose of an interchangeable thumb slug is so that every ball has the exact same feel, and also that it can be swapped for a different size if your thumb starts to swell up in a long tournament.

1

u/ecafsub 7d ago

Yep. Many balls are made with 2 different materials and when drilled the transition between the two is exposed. The innermost is typically coarser material while the outer is smoother. Certainly uncomfortable without the insert as well as affecting gription.

u/littlegreenrock 8d ago

Is a custom ball, with custom diameter/shape thumb hole not allowed, or not an option?

3

u/ecafsub 7d ago

It’s a lot easier to drill a round hole in urethane and then slip a plastic insert in which can be shaped, rather than trying to file/sand the urethane. Thumb inserts are typically oval-ish whilst finger are round with a little lip to grip. The angle of the lip can affect loft and spin when releasing.

u/frichyv2 8d ago

Inserts are still used on custom balls.

So you’re saying girth is more important than length?

I get that, but why is it red?

u/ocelittle7 7d ago

You can get them in many colors, it's for aesthetic purposes, however the fingertip insert colors for some brands determine the softness of the rubber for different feels.

Kind of feels like cheating, right? You wouldn’t allow a some kinda grabby stick in Hockey, why allow a glove which can just… slip off?

No shit its not his actual thumb, as if he would be completely calm if that happened.

u/Miserable-Neat9370 8d ago

Yes and I bet it was a turbo grip. Should have used JoPo grips. Much better product.
