If you're reading this, you probably want to make an atlas stone, and you're too cheap to buy a fancy mold. I don't need to tell you that stone lifting is a great tool for building muscle and real world strength. It's also a lot of fun, and a great addition to your training. So, let's get started...
You will need:
Plaster of Paris
Something to smash the plaster(I used a 9/16" wrench)
Procure a smooth inflatable ball. You may have one laying around, or may have to find some unsuspecting kids on a playground and catch them slipping. I went to Kroger and got a 14" diameter ball for $6.99.
Cover the ball in Plaster of Paris, leaving a small hole at the top. This is going to be messy.
3. Grab a couple beers and let it set.
4. After the plaster is dry, deflate the ball and remove it from the hole. Now you have a stone mold. Let it marinate overnight.
5. Either save the ball for your next stone, or inflate it and give it to a kid. Kids like inflatable balls. If you stole the ball, you may want to give it back and start fixing your karma.
6. It is now tomorrow. Start making concrete. Keep it clumpy and make sure you stir it up real good. Then, fill the mold up with concrete. Save a little aside, because within minutes of filling it, the concrete will settle and you'll need a little more.
If you're impatient and need to see this thing now, you may chip away the plaster after about 6 hours. That's what I did, but I recommend you give it a day or two. Some of the outside wasn't quite set and came up with the plaster, leaving behind a pretty rough texture. On the bright side, knocking down the spot where the hole was and rounding it off was really easy.
Let it marinate for a week or so before you do cool things with it. In the meantime, go ahead and take a couple of pictures with it, find reasons to carry it from point A to point B, and tell all your friends about it.
That's about it. It's really pretty simple, and messy. Real messy. Gloves are nice. And old clothes that you don't care about. Hope this helps!
