Debut of the Stonebell

It's done and it works great!

My experiment in creating the perfect Stonebell was a success. It's got the shape of a regular iron kettlebell (for the most part anyway), but you can make it at home with some concrete and a few other materials. Here's a couple of photos:



Here's the short version of how I made it:

  1. Cover a children's play ball with plaster of paris, leaving holes to insert ends of the handle into and a way to divide the plaster shell to get the handle in.

  2. Once plaster is dry, deflate the ball and remove it.

  3. Make the handle out of stiff 1-inch diameter rubber tubing over a 24" piece of re-bar.

  4. Place the handle between the two halves of the mold and tape the mold together.

  5. Mix up and pour concrete into mold.

  6. Let stand until concrete is hardened; remove mold and allow to cure for about a week.

  7. To make it adjustable with barbell plates, before pouring concrete screw a 1/2-inch diameter bolt about 3/8 of an inch into a threaded-bar coupler and suspend the bolt end of it in the center of the mold. The open end of the coupler should be flush with the top of the mold so that, in the end, it looks like this:


Use another bolt and a washer to bolt barbell plates onto the bottom. I use a 25-pound plate in the photo above, but 10 and 5-pound plates work just as well.

I haven't had a chance to write up the detailed instructions, but will do so before too long and make them available to you all. For now, take a look at my video using the Stonebell.

Hey now, I am trying to copy your epic design but I have two questions. How did you bend that re-bar, and how do you measure the weight of the Stonebell before you mix and pour it. Great design, thanks.
