- A quick video to show you how to make great quality plyometric boxes and Atlas stones for functional training work. For $50 you can make 7 boxes and 1 top that can be used in 5.5" increments all the way up to 40" plus. These are 24" squares with 3/4" plywood top for the top section and are extremely solid and can handle any size athlete. The Atlas Stones are fun and easy to make.
just wanted to say that we just made the box, and while a little tedious, works great! thanks for this!
ty this is amazing i cant wait to make my first atlas stones this summer thanks again!!!!
I've made three stones so far this way. It works great! If you've never done this, make sure you only mix as much plaster as you can slather on in about 5 minutes. The bag isn't kidding when it says it sets quickly. And for the love of God, don't accidentally press down on the ball while you're putting on the plaster. Once it hardens, you'd be surprised how much weight it will hold. I only used one bag for a 110 pound stone, and I'm pretty sure that was overkill. Having some rebar or something to agitate the mix in the mold with is a good idea as well. I didn't have anything and all mine came out with a pretty rough surface. A bucket of patch fixed that and I have three really nice stones! If you're making small stones, wal-mart carries a cheap 9" exercise ball that you can inflate to about 12" and is reusable. Don't go beyond 12" or it will pop. If you're curious about how heavy a stone will be based on diameter, Slater's hardware has a really good guide on their website. For me, I made a 10" which came to 50 pounds, a 12" which came to 70 pounds, and a 14 inch that looks huge and weighs 111 right now. Once I cover it in patch I imagine it will weigh about 115. Quickrete patch works well, it sets quick and very hard. And it sands smooth pretty easily. Thanks for the great videos! This is pretty easy and fun to do and makes quality stones that would cost an arm and a leg otherwise.
great videos. I just used your method to make roughly a 120kg stone, only wanted about 100kg but ah well. I have just finished putting the concrete in. Can I ask how long before I remove the plaster, and how long after that can I use the stone (lift and drop etc)? Also, would it be possible to spraypaint the finished stone a certain colour or can this weaken it?
also, id just add that i would definitely recommend a second pair of hands when making the box
thanks for the reply, this is my first ever atlas stone so I want to start light. I would like a stone in the 100-120 range. What would the diameter for that be? I couldn't find much online about this.
But is there a way to save the hopper for use again? It looks like the air stopper to deflate and remove it is sealed by first application :( Perhaps i missed something there and you could let me know , thanks. They don't seem to make gym balls without the damn rib lines either, doh!
lowes has 25lb plaster and 4lb.. how much is a bag in your video?
Could the plaster method be used to make dumbbells? cant afford 40kg dumbbells.
how thick do I put on the plaster of paris?
did you use pure cement for the balls or what was the mixture? did any of them break yet?
Go out and buy a cheap ball from Walmart that is 15" in diameter. To get 100-120 lb. stone a 14" diameter ball should be the size. deflate or inflate the ball and run a string around the ball. You are looking for a string length of 14 X 3.1416 0r 43-44". 1 bag of 25 lb. plaster will work as well for this size stone. Good luck.
1 bag of plaster per ball or 2 bags per ball???
I made 150 to 300 lb. stones and you can probably get away with 1 bag for a small stone but 1 1/2 bags or so for a big stone. Good luck.
25 lbs will cost about $15. you will need at least 25 lbs for 150-180 lb. stone but buy 2 bags.
with a small channel like this u should aim in making shorter videos...
