I think the consensus here, and We have seen these type of threads before, is that the only way this makes sense is if your making a unique shape weight for a specific purpose. Atlas stone or some other piece that maybe replicates a strength event or type of training not easly done with regular weights. First, the amount you need to make a usable set of weights is a lot of work and the smaller weights are going to be difficult. Consistancy is impossible, plus they will crumble and crack pretty quick.
If your doing it to just play around to get the technique down to eventually make something not really available that's cool though. But to work a week or two of free time to make a really marginal set of weights you could have picked up on Craig's list for $120. That will work infinitely better doesn't work out

I'm a DIY kind of guy. This stuff plays right into it. I am also making some planters for the patio.
Figured I would try these and see what happens. I was thinking of wrapping these in some kind of rubber so if they drop they won't break. We will see.
There is a local guy who sells Atlas stones them for extremely high prices (to me at least). Might have to try making one and see what happens.

Usually the reason they are expensive to buy is
1. Labor, making stones sucks. Especially if you make them "nice"
2. Molds are expensive
3. No competition, generally.
I made some with a buddy of mine because he had molds, it was an all day affair and I still wasn't able to get as many as I want.()---() York Barbell Club #76 (RH) ()---()

I think most of us around here have a lot of respect for DIY projects, but there is definitely a reason why concrete plates never really caught on, even with rubber/plastic coating.
An Atlas stone or some other "strongman" type project would be a better way to channel your creative urge. Take a look on Youtube before you start....there is probably something you could add to the concrete to strengthen it.[]---[] Ivanko Barbell Crew #29 []---[]

The Atlas Stones moulds are expensive, (just googled it) I can see why they cost a lot let alone the time making them.
Might have to try to make some and see what happens though. There is one seller in Ohio that I know of, but nowhere near Columbus. I am all for making a few bucks on the side.
Will get these hopefully 10 pounders out tomorrow midday. About 36 in the mold at that point.

If you search youtube, you'll find several DIY videos which show how to use a plastic inflatable ball to form the mold. The videos I've seen allow you to reuse the plastic ball, though the mold itself needs to be broken away from the stone. One of the videos used plaster of paris and the other used a form of paper mache.
If you want to make a bunch of stones of uniform size it's probably worth it to invest in some quality molds.▪█─────█▪ Equipment Crew #35

I did that with plaster of Paris one time, would not repeat.
It's a lot of extra work, especially breaking the mold away from the finished stone.
And, it is very difficult to get the correct diameter because the air inside the ball expands when the plaster heats during the curing process.
I measured a ball to create a mold for a 360# stone and it ended up being 402# because of the larger diameter when the stability ball expanded due to the heat.
If you're serious about stones, just use Slater molds. You can usually get away with just one mold and still make a huge variety of weights with lighter concrete or just adding old plates inside of the stone.()---() York Barbell Club #76 (RH) ()---()

Well I got them out tonight. The PVC was a little stuck, but a rubber mallet and a screwdriver knocked it right out.
I think for never making these before I did an okay job. One does weigh 6/7 pounds while one is 9 pounds. I didn't use a proper scale (bathroom scales are junk) so they are a bit off. I know with humidity and how concrete is they might not weigh exactly the same, but I don't see how one lost 2-3 pounds unless I weighed wrong.
I will definitely wrap them in a some kind of rubber (something cheap) so they don't break too easily. They do fit on the bar and will be putting duct tape on the inside of them so they don't destroy the bar or vice versa.
All in all they did the job. I did some squats and dead lifts using these today. Will try to make some more next week and be a little more precise on the scales.
Now the pics!

I don't know if it was the scale or the mix. It's very possible the lighter one was a "wetter" mix so the water would have added weight to it that would evaporate out during the curing process.
Also, air pockets are a big problem with concrete (at least with stones). You have to really vibrate the mold to get the air out and ideally get as much out as possible.()---() York Barbell Club #76 (RH) ()---()

I remember reading about how there can be air pockets after a few minutes of putting the mix in he buckets. Dropped it a few times, but didn't spend too much time on it.
I am going to try weighing out 9 pounds of concrete and then the water and repeat for the next batch Monday. Just to see what happens.
If it is still off by 3 pounds then ehhh whatever. We will see.
Thank you.
Will do! http://rosstraining.net/forum/viewtopic.php?t=64585 Two or three posts down and you will see what I envision in a concrete weight, lol Some weights would be nice too.
Nice one.

I've used a handheld buffer on a mold and a rubber mallet. Honestly, I think the mallet works better.
You can't wait until the end to do it either, you really have to shake it out every time you put a scoop of concrete in the mold to settle it out and get as much air out as you can.
I still don't know how accurate they could truly be, because it won't cure consistently and the amount of aggregate will likely be different between each plate.Last edited by jimbuick; 05-08-2016 at 09:27 AM.

Well I am attempting to make some deep dish plates. I tried to make one Monday and just took it out of the bucket today. I don't know what I was thinking. I basically made the inverse of a deep dish plate. Ehhh, live and learn.
So I figured out the correct way of making this deep dish concrete plate. Put styrofoam to take up the deep dish part with the sides open.
A few pics.
It won't be perfect or have anything inside it to keep it stable , but I just need to see if the concept works. All I had was 3/4 inch foam so I just stacked two pieces together totaling 1.5 inches. Will be cool to see how this works.

I think your original concrete plates are deep dish enough. Haha. They're like 5" wide already!
The good news is, once you're done with the concrete weights you might be able to use them as currency on the island of Yap! Haha.
