[@jonathonhare1981]

This method is excellent. I did almost exactly the same thing a few years ago, down to the screws in the wood to keep the form in place :) Notes: - Concrete Sonotubes: Waxed inside releases easy, can be used a few times. They come in various sizes. - 2" Abs pipe needs to be deeply scored on the outside surface (the part that needs to bind to the concrete), or it can pop out of the concrete plate - 1 7/8" Galvanized fence post makes a perfect bar for this system! Fill it with concrete so it can't bend (no flex, wide grip bar, makes it tough!) - Concrete is about 1/3 the density of iron, so your plates need to be BIG (ie ~18" like olympic plates), and thick. - Heat gun-flattened 3" abs pipe inserts as handles, so you can carry it like a normal plate. Love the buff videos!

[@rp003.0]

so you just weigh the dry concrete I imagine? otherwise the gallon of water ends up drying out and making it lighter

[@MrMarkWilley]

@@rp003.0 The magic of concrete is that the water becomes part of the final material permanently through a process called cement hydration. Concrete doesn't cure by "drying out" it cures by incorporating the water. But your intuition is correct, there may be some change in the weight as it cures. A cubic yard of concrete will go from about 3900 lbs to 3600 lbs or so. In the case of DIY plates, it's really only important that they're "close" to the desired weight and balanced as a pair. The difference can be made up by adding fractional change plates.

[@marijn1772]

Great vid, didn't expect they would be so strong. Maby an idea for follow up video, drop test or something to see how much they can handle. Shame to break them, but would be an entertaining video. Keep it up, fun and entertaining as always.

[@jonlanier_]

@@jonlanier_ Sounds like you didnt watch till the end, he drops it at full height? :-)

[@JamesPhillipsOfficial]

Yeah he did a drop test and it passed. Most people dont watch to the end, shame. But also on a hard floor you can just make up a couple of sand bags and a raised platform for deadlifting so there's no real excuse, most movements other than deadlift dont even require the weight to touch the floor except power clean row (floor to overhead, back down) And if you didnt want to use sandbags, you can make up a small trestle so your concrete plates have a 1/2 to full inch clearance of the floor and again use a raised platform to maintain the bar height of 9inches off the floor, or less (IPF standard limit)

[@kiyoponnn]

lol buildings are made from concrete and steel, of course they are strong

[@brianfederico5854]

Just a friendly tip. Put diesel into a spray bottle and coat everything that the concrete will be touching. Get a thick coat on there then lightly rub it in with a rag. I promise you it will work better than any lubricant out there. I've been doing concrete my entire life and they don't make anything better than diesel for form oil

[@franklingomez5311]

Hey Duke, did you know you can improve the mechanical characteristics of concrete by adding extremely fine particles to the mix? Fine activated charcoal powder, at a concentration of 4% dry weight is sufficient to reap the benefits and activated charcoal is very very cheap. This addition gives a few interesting characteristics to the concrete like resistance to cracking when exposed to high temperatures and resistance to permeability by water. The reason it works is because when there's much smaller particles in the mix, they fit in between the spaces that the larger particles of cement just are not able to. This causes a lot of the of the porous voids that normally form in concrete to be filled and so you get a higher density concrete with improved mechanical characteristics. Superplasticizers can be added to the mix water to make the water wetter. When you use superplasticizer you can use less water in your mix and still achieve the same wetness in your mix, this will also have the effect of increasing density.

[@thomas.thomas]

Wow Duke, I was a bit hesitant of how heavy a concrete plate set can be. But man, that plate is heavy. 6 of those , ie, 3 each side on a 45 pound barbell can reach upto 475 pounds. For Non-Americans like me, that is roughly equivalent to 230 kg, which is more than enough for regular home "gymmers". In fact you can be a beginner to medium intermediate powerlifter with those plates. Duke, you are awesome !

Is it possible to cast your own metal plates from scrap metal? Thanks for the video and your time.

[@dennissvensson6051]

Yea, but very few have the equipment you need to melt and cast something that big.

[@kinnikuzero]

It is if you have the right equipment. You'll need a huge forge and a huge crucible, and some sort of mold. I can imagine doing it with lead and tin, anything other than that would be impractical imo. Just use your common sense and don't breath in the fumes. And maybe coat the lead with something you don't want a lot of exposure.

[@stoneskull1673]

Takes a whole lot of heat 2 impractical

[@bobbyrejek6013]

Depending on how you forge it, you could also introduce cracks, fractures, and air pockets into the iron which could lead to rust or it even falling apart on you, which could be dangerous. Not saying it's impossible, just that there's much more to consider since it isn't just about heating up iron and pouring from a crucible or sticking it into a forge and pressing.
