Regarding home-made sand filled BB.
We’ve busted about every style of ball out there. Lately we’ve been breaking 1-2 per workout. In a 2 week time span we will use the ball 3 times so we are burning through them.

Thoughts:
1. We slam on hard pavement - no real choice here in the City of Philly.

2. The temperature has dropped, could this be a factor?


I think I will date this next batch and estimate after each workout how many slams it endures - then I'll have a count when it busts.

I don't mind them busting every so often but we’ve been on quite a tear lately.

Thoughts?

I've broke a couple older versions slaming, even on grassy ground. It's a lot of weight/pressure on a ball not designed for weight. Cold weight would likely make the rubber stiffer and more likely to split, but I broke mine in the heat of summer. It might help if you brought a cushion to throw them on. Like a old seat cushion or like a larger version of those pads people use in a garden...

While heat would make the ball more giving...cold will certain restrict it's stretching point...may want less air or less sand to reduce the internal pressure?

Are they breaking at a the site of the sand filling hole? Do you have air in your balls(LOL!, sorry)?
Try some higher end balls.

Was going to add....if your cost of making a new ball is $15-$20 a pop...then you might just want to get the D-Balls which are under warranty (I believe). Every 3 homemade balls could easily add up to one new D-Ball that will last for years...just figure out the cost of business, may be worth it.

Thanks.

1. No air added - I was actually thinking add some air, might help with impact?

2. Only one has broken at the puncture spot.

3. The D-ball plug is not under warranty and from what everyone says that's where it breaks!

4. Cost is 10 bucks a pop (I have plenty of sand), they are fun to make- looking to tweak this or see if I’m doing something wrong.

I went out and bought four Nike BB's - we’ve never broke those before! HA!

I bought the 29.5", so there is plenty of room - You think using less sand might help? I'll give it a shot...

Last place I worked had the D-Balls and we used them for slam balls. It was the rubber plug that cracked...although the person who bought them got a new one from perform better. So I really don't know what the warranty is or maybe it varies by reseller?

No idea if air or less sand will do the trick, but I guarantee those cold Philly winters is the real culprit!

Maybe you could reinforce the seams with shoe goo?
Also, check out TJ Max for BB's they have some from time to time that are high end but cheap.
Other than that I would say to get some higher end BB's. I have an old Spalding that has not broken yet. It's might not get as much use as yours.

I have repaired 3 of my homemade slam balls by roughing up the area of the tear with a wire brush then using the shoe goo to fix it.



I am also under the suspicion that less air inside is better (like trying to pop an under inflated ballon). I try to make mine with all sand and very little air.

I also don't slam my cheap ones any more. I only let my clients slam the $10 ones and just use the other ones for basic medicine ball stuff.

Has anyone tried filling a bb with water rather than sand? Not sure how heavy it would be, but maybe the water would disperse the load of the slam reducing the chance of busting??
