I just purchased the starter kit today. I'm just a garage driller/pro shop type guy but I am very excited to start drilling some balls with the JoPo Twist!

I am sold on the system. I want to install this in all my bowling balls. However, I also want to try something I haven't done before, oval thumb slugs. How is that executed??

@2bcsparky 2 күн бұрын

How do you line up subsequent outers so that the inner snaps in in the correct orientation on an oval thumb hole?

Made the switch to the JoPo twist in one of my older bowling balls recently. I only had a couple of issues in my 2 1/2 years of using the VISE IT system. No bad feelings against the VISE IT, but I feel the JoPo Twist is a better product. I will eventually over time, have the JoPo TWIST installed in the rest of my bowling balls.

Just curious because it seems with all the systems eventually the thumb starts to stick from ball shifting internally. Can the outer sleeve be sanded to free up the inner like the other systems?

@jopogrips7657 3 ай бұрын

We do not recommend sanding the inside of the outer as the threads may be sanded down too much. PSOs have done it at their own risk though. If there is any ball compression, drilling out the outer and replacing it will do the trick!@@crashbang7217

I just gotta say that if VISE put a 5/8" hole in their slug-IT's, the Ferrari JIG would be totally obsolete. I ordered the JOPO starter system for my shop this weekend. Looking forward to trying it out.

How deep is the JoPo drill bit into the ball when against the stopper? Just ordered the starter kit, looking at drill presses and trying to determine how much travel is required. Thanks.

@jopogrips7657 Жыл бұрын

Hello Kenny, the drill bit is set to 3.22"

Why do my thumbs get smaller at the bottom.. it also makes my inners tighter

@jopogrips7657 9 күн бұрын

That sounds like it may be a core compression issue. It happens on some bowling balls with all interchangeable thumbs. You may reach out to your PSO to help and if they have any questions, please have them reach out to info@jopogrips.com

@erict4014 Жыл бұрын

so the pitches are on the sleeve and not in the thumb itself? better to go 0/0 on the sleeve and add pitches in the thumb?

@jopogrips7657 Жыл бұрын

We recommend that you put the pitches into the ball, but you may put 0/0 pitch in the ball if you go 3/16" in any direction.

if my ball already has jopo installed and i wanted to change my span can i plug it and redrill it?

@jopogrips7657 11 ай бұрын

You will have to drill out the outer, plug it, re-drill it and install a new outer!

@tylerstine784 Жыл бұрын

Good idea....looks like it secures well.....the hole already in the slug is not a good idea though. Just put through lathe and use centering bit to mark it for pso. Terrible idea in the idea you have a customer that wants to change pitches with a small thumb, you can get away with 1/4 in the turbo system without having issues or plugging, this would not allow that as you'd have an oval hole front to back towards the bottom if customer had small thumb. But does look like this idea secures the slug pretty well

Also for 10 dollars or less to sharpen the bit I'm not going to spend the time cutting the 1 1/8 hole first. Just lock the table and punch it

@jopogrips7657 Жыл бұрын

Hello Tyler, thank you for your feedback! The hole is needed for the PSO to install into the ball. You can still change the pitches 3/16" in any direction as the hole is small enough!

@jopogrips7657 Жыл бұрын

The hole also saves the PSOs equipment as there is less wear and tear on it!

@@jopogrips7657 I'm going to give this system a go in my pro shop in a week or so here and see how it goes over, personally I believe this is probably the best IT on the market from what I see. Just have an issue with the hole, if it's like a 5/8 and I'm trying to run a girls 3/4 " thumb 1/8 more reverse she's going to have an odd shape hole front to back

Only issue that i have is my thumb inserts dont always want to come out while bowling. Makes it hard to switch balls when my thumb wont twist out

@jopogrips7657 Жыл бұрын

Hello Jeff, We do recommend also having the twist tool on hand just in case you are unable to get it out of the ball with just your thumb

At no point while drilling was the ball clamped down on the press, it was just sitting there, completely insecure... Then proceeds to use Acetone (a banned substance) on the ball, so now the ball is illegal.

@jopogrips7657 3 ай бұрын

Acetone or rubbing alcohol is used on the inside of the drilled thumb hole to clean out the debris only. This will ensure the glue adheres to the outer efficiently. As the video does not show the PSO physically clamping the ball down, the ball is clamped down on the press as you can see on the close up shot at 0.28 seconds in.

@rkaycom 3 ай бұрын

@@jopogrips7657Acetone is listed as a prohibited cleaner, literally listed as "NOT APPROVED EVER", it's not to be used on a bowling ball for any reason, at any time ever. Not even in the drilling process, there are plenty of other cleaners (like rubbing alcohol) that can be used to clean the ball for glue. You are incorrect about the ball being clammed, the ball is literally drilled without being clamped from 44 secs in until 2:17, during the entire thumb drilling process, no clamp.

@jopogrips7657 3 ай бұрын

Acetone is banned for the surface of the ball, meaning any surface that touches the lanes. It is also prohibited to "alter" the surface of the ball and also prohibited during play - not prohibited when cleaning the inside of the drilled hole. Many pro shops use acetone or rubbing alcohol to clean the inside of the drilled hole and we cannot control what is used, but we appreciate your concern and comment.@@rkaycom

@rkaycom 3 ай бұрын

@@jopogrips7657 Incorrect, Acetone is not approved at any time, never shall it touch the surface of or any other part of a bowling ball. It was originally banned because people use to soak balls in it to make the balls softer. Since then it is COMPLETELY illegal to use it on your ball for any reason, at ANY TIME EVER. That includes cleaning out thumb holes after drilling. Yes, lots of people do it but they aren't meant to be, it shouldn't even be in a pro shop, it's like having steroids at a gym. Argue as much as you wish. But thems the rules. I've never used it, never needed too, never had a problem with thumbs coming unstuck with a simple vaccum out of the hole and enough glue.

Are you allowed to bevel the inner slug?

@s_k_fishing7313 Жыл бұрын

Also if a pro shop does not have the Jopro drill bit. Would the turbo drill bit work? My local pro shop only does the turbo or vise switch grips. I’m looking at ordering the jopro kit off line and have them install for me

@jopogrips7657 Жыл бұрын

@@s_k_fishing7313 We do not recommend beveling the inner as the product is meant to be flush to the ball. The only way if you must do it is to round the inside of the inner so it is not sharp against the thumb. As far as our JoPo drill bit, we recommend all pro shops to use the same calibrated drill bit to ensure pro shop to pro shop repeatability. So if your local pro shop starts drilling more JoPo products, they should purchase the drill bit or starter kit!
