Project - Making my own Reactive Bowling Ball

As the title says, I been thinking about this for a while now. Watching how Storm came about mixing their Urethane in a KFC bucket, to all the videos on "How balls are made" etc, got me thinking, "Can I make a ball at home".

So I think I want to go ahead and try this. I want to document every step and after its finished, failure or success, want to upload it to Youtube.

The Goal
To make a 15lb Reactive symmetrical bowling ball.

What I need

1)I want to be able to have my own forum or a way I can allow certain people to comment or not. Revzilla, please PM me with a way that I can do this. As we all know, I have people that dislike me. I do not want them interfering or trolling along my success and sure, many failures.

2) Mathamaticians. I need people that are good at math. I am going to CAD my own core so I will need to know how to get differentials, RG's, etc.

3) Chemist - specifically people that know something about urethane's along with other materials that I will need to make the core out of, how much filler for the inner core, and how much resin to use to make a 15 lb ball.

I think this can drive some traffic to this site again. So if you know people that can help or want to donate towards materials, please have them sign up. I will someway give credit to EVERYONE that helped along the way.

What I already have
Not much. I have a 3D printer that I can design my own core. I am thinking I would then have to vacum formi it to pour the material.

Pro shop tools. Haus machine (to make it perfectly round), drill press, scale, etc.

Adobe Illustrator - allows me to make vector images for the logos

What I need
Knowledge - I need to know what I need, materials (ie, lathe) etc.

I am thinking this will probably take a year. I hope that anyone that is interested to follow along the journey and if knowing someone that could help out. I think this could be a really fun and interesting project to see if this can be done at home and be cost effective.

Re: Project - Making my own Reactive Bowling Ball

I'm very interested in following your journey.

Is the plan to start up a new company eventually if this goes well, or just doing this to see if you can do it? Regardless of what your long range plans are, I'm excited to follow along!

No, not a new company. The business is brutal. The bowling ball market is over saturated as it is. This is more of a challenge to myself.

Re: Project - Making my own Reactive Bowling Ball

While we may disagree, most certainly, I wish you much success!

I have a friend who owns a grinding company, does aerospace projects. A while back, I asked him how I could make a bowling ball as round as possible? He said, a centerless grinder would be best, but also felt it could possibly be done on a lathe.

Too bad, this is twenty years later, I had a lathe. Would have just given it to you. (It was huge, transporting it would have been a bear)

Good luck!

A name. hmmm. No not yet, maybe part of the build process will be having people submit names and have a vote on the best one? What do you think?

We will see. To be honest I havent even thought that far in advance yet. Still thinking about all the materials and reading I have to start on.

Re: Project - Making my own Reactive Bowling Ball

So I need to look into these materials

Barium, Silica powder, limestone for the core

Anyone have any experience with these materials?

Be aware of inhalation dangers with silica powder. I don't have any working knowledge of its properties, just the haz mat side of things.

Interesting, I also see that a lot of compaines use powdered metal oxides like calcium or iron oxide

I was thinking about something like fiberglass sheets to reinforce :o

What about clear reactive resin :o

What about things I would never be able to figure out?

Something like Quantum is doing right now? I guess I have to find out how much the coverstock would weigh and offset that with how much the core weighs to get 15 lbs.

I wonder why most companies use filler material, cost maybe? Does it allow them to make heavier cores? So they dont have to use as much reactive?

Re: Project - Making my own Reactive Bowling Ball

I think (IIRC) the USBC limited the density of materials allowed in ball construction. With lower density materials, a larger core would be needed to get a low RG ball. But, filler cores are used on high RG balls too. Maybe filler is cheaper than resin. It might be harder than resin too for max coefficient of restitution within allowed limits. It may even cure quicker and speed up production lines.

Of course, I have no real idea and can only guess.

As a practical matter. you will need to know the density and volume of each material used in your design to arrive at a desired weight.

Maximum density is 3.7 and yes, filler material is much cheaper than resin.

Re: Project - Making my own Reactive Bowling Ball

MeNo, if you are Mac based, there is a program out there called "Autodesk Graphic" that is so much like Adobe Illustrator that it's hard to believe there isn't a copyright issue with it. It does almost everything Illustrator does but it only cost about a third. Give it a look and Good luck.

Thanks. I'm.PC based but been using Adobe products since CS3. I have a strong understanding of illustrator. Now to get a cnc machine that Mills into a round object. That's another story.

Re: Project - Making my own Reactive Bowling Ball

So I have a ton of information gathered.

So my first thing I will do is design the core. If anyone can find out how to design for RG and Diff would be appreciated. I remember from the advanced class that for RG its x/y.

Re: Project - Making my own Reactive Bowling Ball

I don't think I'd worry about the USBC approval at the beginning of this. I'd try to follow the guidelines so you can submit it if that's your goal, but I'd put it on the back burner for now.

Good luck in your endeavor, I'm interested to see how it turns out

Good point. Right now my brain is all over the place. I need to focus on one area, complete it and move on to the next one.

Re: Project - Making my own Reactive Bowling Ball

Definitely a cool project. I was always kinda interested in coverstock chemistry myself.

I was reading an article the other day about new carbon fiber nanotube reinforced resins that are extremely hard, and impact resistant.(Future of vehicle panels, bumpers, and injection molding high durability parts) I know Storm and Hammer have both released carbon infused balls in recent years, but I don't think anyone has found a way to really harness the power of the material outside of a gimmick yet.

It could very well be the future of incredibly thin and durable coverstocks that never need surfacing. Probably the biggest hurdle would be the cost, as these resins are extremely costly.

Silica powder a thickening agent. Cabosil is probably the most widely known brand. It can be used to thicken adhesives, epoxies, resins, etc. As mentioned earlier, not great for the lungs.

Barium is similar, except it is a much higher density than silica (because it's actually a metal). It would be more useful in adding weight/density, whereas silica is nearly as light as air, and only changes viscosity. Barium sulfate is more than likely the actual compound used in bowling applications, as barium itself oxidizes almost immediately when it encounters oxygen.

Wow, good stuff.

For the core, I will have to add something that makes it heavier, since I believe cores can be 8 - 10 lbs

The outer core, is the one they use the glass beads, which is like fillite I believe.

Thanks for the information, I will start looking to purchase the material

Re: Project - Making my own Reactive Bowling Ball

This video has helped me a little, since I am terrible with math, I will have to get someone involved in figuring out mixture rates to get specific weights

Re: Project - Making my own Reactive Bowling Ball

Generally speaking, this article won't help much in the manufacturing of bowling balls. However, if you scroll down past the pictures, there's some really good math about the volume and density of bowling balls. Knowing the total volume, combined with the weights given in the track video, you can kind of divide out the equal parts of each individual layer. Obviously, your core may not weigh exactly 6.9lbs, or whatever it was, but it gets you in the ballpark.

Re: Project - Making my own Reactive Bowling Ball

Limestone is calcium carbonate. You want to get some ground to a fine powder (particles sizes in the less than 30 micron size. There are several manufactures of mineral fillers: Emerys, Omya, Specialty minerals. Often they have a coating to help them mix and disperse in the particular material (in your case polyester).

For coverstocks: BASF and Bayer are developers in this field. So much of this appears to depend on the length of the alpihatic portion of the ester/ether. This is the chemistry control for the softness/elasticity. I remember reading a fairly clear patent published on this.

I know that either Bayer or BASF makes the resin for Brunswick. I am not sure how they would treat someone just looking for some coverstock. I will do some research on ester/ether.

Thanks!

Bayer - Brunswick
BASF - Old SA Columbia, may still be working with 900?
HK Research - Storm

Re: Project - Making my own Reactive Bowling Ball

Sounds like a fun project. Who was the guy on here that found an old core in his shop, and mounted in a mold? He would pour left over plug in the mold everyday until he actually had a ball. It took him over a year, but he had a video of him drilling it after it cured.
