Drilling the Fingers of a Bowling Ball - Innovative Bowling

Basic Instructions on how to drill the Fingers in a Bowling Ball

[@coasterbrain1017]

I have to thank you extremely much! You have made me completely understand how to label a correct span and bridge, as well as accurately drill pitches!!!! Definitely a subscriber!

I am trying to get my first custom bowling ball. How do I measure my hand & fingers? What are the measurements that are used for drilling the holes? I'd like to make sure that my fingers get in the holes perfectly & that the holes are the perfect depth/width. Thanks.

John.. Tsk tsk... You should be using the Jonell span gauges. That metal thing is good for a Frisbee. Mo's words, not mine :)

Eyeballing an almost-one-inch cut to a wax pencil line is top-level engineering. Take an awl or punch, make an indention at the exact center of each hole. Drill or at least Chuck-up an 1/8 bit to get it dead-nuts to the center mark, then step up your bit to 1/2 or all the way to 31/32 insert size with it still clamped down after the 1/8 but center-check. I started drilling my own when I measured my balls and found them as much as 7/32" different that were supposed to be identical. It's not rocket science, and not needed to be as accurate as a first week student in a milling machine class. But it needs to be more accurate than your eyeball from 2 feet away.

The only advantage I can see for drilling the thumb first would be for a bowler who heavily bevels the hole to the point that it would alter the span after drilling, so in that case you drill the thumb and work it out before drilling the fingers. Even in that case, I believe you can drill the fingers first and accurately hit the desired span. Remember pro shops exist to make money. Speeding up the process by drilling the fingers first can only help--I agree with aello465

Let me offer another perspective in thumb/finger drilling sequence for other viewers. You should drill fingers first because once you have both of them drilled, what happens if you accidently drilled one or both slightly off mark? You simply position the thumb left or right of the original centerline to keep the spans correct. The grip is only rotated the slightest bit, which will have no effect on the intended reaction. Rather than drilling thumb first and trying to be accurate on TWO holes.

Why are you drilling the hole in the wrong place. Measure twice drill once. Haven't missed in 37 years

[@kylewagner6607]

Also dont just mark the outside edges. Measure the center and mark it. You cant miss

I have a question. I just started to learn how to drill balls. For the fingers you said 3/8 left so you cranked the handle so that the table shifted to the right which is correct. This would mean that left is right and right is left for lateral pitches. . Following that methodology for the thumb you said 3/16" reverse. So shouldn't you have moved the table away from you? At 5:48 in the vid the table moved towards you. This is where I got confused. To me that would be 3/16 forward pitch. Thanks.

He was drilling the ring finger/right finger. Moving the table away from you for a THUMB would be reverse pitch.

[@MriTzBiGENGLAND2You]

got to a local pro shop... they will help you out and its like 40 to 60 bucks. they will measure the correct span and everything

[@skwira000]

Let's remember he's demonstrating how to use the Starter Pro Shop kit. Of course a well established pro shop would use Jonell.

[@JMacTucker]

It's not the wrong way. It's most likely their preferred way, or the way they learned it. It's not wrong to drill the thumb first or the fingers first, so long as their are less than the allowed limit of holes and it's drilled to hook without being an illegal drilling and fits properly, i don't care if they drill one finger then the thumb first...

[@torianalee1]

why are fingers always drilled in line with each other. the middle finger and ring finger arent the same lenght. What would happen if the the middle finger is higher and ring finger driled lower?

[@madrox4132]

That's an optical illusion

[@JMacTucker]

Every pro shop owner that has ever drilled a ball for me has done thumb first.

[@ruralrenderer]

I agree

[@Daveyo747]

I wonder what happened to their super duper computer milling machine, and vacuum lock with their expensive keyless chuck??? I see here this guy is still doing it the old fashioned way.

[@thestime]

The camera is always too low in these videos.

[@aello465]

Now you know that all of them have done it the wrong way I guess.
