The thing I've missed most about having my gym closed is having access to a set of dumbbells. When I saw some large pieces of 1/2" plate at the scrap yard recently, I had the idea to make my own set. Each dumbbell needed a different diameter of plate cut on the CNC plasma cutting table, to match the target weight. I used 1.25" round bar for the handle, which i welded the plates onto. After all the dumbbells were welded, I hauled them in to get a poly coat at the powder coater's. While they were getting coated, I switched to making a flat bench and a seat bench, which is what I found myself using the most at the gym. I cut the wood backing on the CNC routing table and installed recessed T-nuts. I used 3x2" rectangular tubing for the frame. I bought some black vinyl and sewed seat covers, which got stretched over the wood backing and stapled. The last thing to build on this project is a 2 tier rack to hold all the all the dumbbells. I cut the uprights on the CNC table and welded on angle, which the dumbbells will sit on. I milled saddles out of 1" UHMW and bolted them to the rack. Once the dumbbells came back from powder coat, the last thing to do was make stencils and paint on the weights of all the dumbbells. This was a huge project and I'm excited to start using them!
Here's a link to the dumbbell weight calculator spreadsheet I put together:

Are you off Instagram for good?
That vise jig was sooo satisfying to watch being used. Amazing work on this
I have a ton of 3/8" scrape plate. Id want to keep the same number of plates you are using-the diameters would have to got larger. How would I edit this spreadsheet to use 3/8" plates?
same question here how do i change the thickness in the document, thanks for supplying us with the spreadsheets by the way
Adjust the weight by the ratio of the weight of the thickness of mild steel
I'm speechless, you're an absolute genius
Its called engineer around the world and it achieved by going to school. Only in uk engineer is a job not a person and everyone can be him/her

Yes, he’s an absolute genius with a $30,000 plasma cutter.
@@rightreasons7908 he's genius that he makes a lot of money so he can buy his own plasma cutter
What a range of talents! Design Engineer, metal fabricator, welder, machinist, CNC operator, carpenter, upholsterer, painter, videographer and … athlete. Well done.
Don't forget forklift certified
Truly a man of value
Я бы в ваш список добавил ещё и актёра
100+ years ago being this way was a standard for men. I know nothing about this guy, just happened upon this video, but he probably had a dad that made him help with all his projects and tasks. Teaching kids how to and including them in your work at a young age creates resourceful problem solving people. You don't have to teach them each individual thing, just the process of learning, doing and succeeding.
Best dumbbell set ever made.
No frills and will last a life time.
Very impressive work sir😎
No knurling. No party.
The entire project looks so professional, it's not difficult to recognize a perfectionist very very well done man
Bro these equipments are far better than those at the most fancy gyms!!! Amazing job!
Dumbbels aren't only a weights - it is also a comfort and safety. The depicted equipment lacks these 2 criteria
@@user-gl6uk8sr5n Are you kidding? Those are over engineered as far as dumbbells go. You might, and I mean might, be correct on comfort as the grips have no knurling or curves to aid grip, but as far as safety goes, these are far safer than the majority of commercial dumb bells. Just inspect the welds on any out there (you might have to cut rubber away) and you'll see that Rainfall Projects is clean while that commercial one has crap welds.
@@epurvee I do prefer rubberized ingots
And indeed it does not matter what is inside - a silver or a cast iron. By the way, the latter is even preferable as it is more sturdy
Fancy looking equipment is for fancy Bros with Instagram accounts, in fancy gyms...
@@user-gl6uk8sr5n you'd be right about comfort, the grips on commercial dumbbells would definitely be better, but absolutely not the safety
This is awesome! Great work!
Coop good to see you over here
Coop should do one of his torture test on them I'm sure they're hold up better than anything you can buy👍
those dumbells have no knurling!
@@saimanullah8523 was just going to post the same comment. Coop's concrete ones aren't in the same league as these, but they did have "knurling". Would be curious to see how knurling could be done with proper tools and skills.
@@graham1034 You will need a lathe machine and a knurling tool to knurl.
The amount of work done here is absolutely insane
The variation of dumbbells is extremely useful for a small person like me czcams.com/users/postUgkxP26Tir6n60vUkdtn4mbwhRO8cwuJQNy2 But the dumbbell size being large it's hard to do certain exercises like deadlift ( I have to have my hands and legs a bit wider to accommodate the size of the DB )Otherwise happy with the purchase. No excuse not to lift weight when it's snowing outside.
Who else here is living through this guy and dreaming of a DIY dumbbell set like this?
Plasma cutter and a lot of large sheet metal
Shit, in that dream I also have the space for that whole rack 😂
Concrete is cheap
Someday if I can actually get everything going on the business end of things I will have the gym next door to the machine/bladesmithing/gunsmithing shop where the dumbbells and fixed barbells were made. Take that Rogue.
Yup been wanting to malke my own for a long time. Just getting the steel is the hard bit.
Thousands and thousands of dollars worth of equipment. This guy Is extremely intelligent. Most people can’t make a birdhouse in shop class.
Tens of thousands of metal-working tools.
Also literally more than $100,000 worth of metalworking tools.
Just the CNC plasma cutter probably clocks in at about 100 grand.
But sure.
@@BjerkeRobin Sure as an amateur you could do this with just a grinder. But you'd go through about a hundred discs and 3 months of work :) And the end result you'd have to say it's supposed to look rustic :)
@@Macatho yeah I know,I have tried with just a torch grinder and welder.there plenty strong but are so much work I made 20lb jumps in weight and just drilled and tapped a hole in each end of the handles so I could bolt 5 or 2.5lb plates on them to get the in between weights
@@BjerkeRobin pretty sure he didn't get all those equipment just to craft a set of dumbells, it is prolly his trade.
What a legend?! one man army! I started studying welding last year and recently got my first job. I am totally in love with the knowledge you have, the workshop you have and the fact that you want to do everything by yourself and you keep at it. That was one satisfying video I saw today. All rounder! Subscriber for life!
Love woodworking and metalworking ,we'd be nowhere without em but the difference between workshops is funny. Woodworking shops looks like heaven and metalworking shops looks like hell.
I’m a welder/fabricator by trade, and also workout. I can’t begin tell you how awesome this was to watch💪🏻💪🏻 awesome job man🤜🏻🤛🏻 and I love the shop. Subscribed ✔️
Hey bro do you make good money?
@@fleecejohnson5750 maybe, but he might be self employed. That's good stuff.
is the cut length actually to the moon and back 3 times?
@@fleecejohnson5750 just assume he does. before i settled down at my nuclear PowerStation as a pipe welder just traveling doing outages welding i made 140,000 only working 7 months out of the year. he's got the freedom to make as much as he wants if he does pipe in addition to what ever else he does.
@@ifiig8220 dam bro. Im just starting out. Hopefully looking to get into production mig welding
Intelligent, patient people are a force to be reckoned with.
Like Gus Fring.
Like Batman
I love how the two m0r0ns up there could only come up with fictional characters lmao
He’s all that, but this guy has most likely been loaded with money since birth
I just did my dumbbels and barbells with concrete, plastic shapes from bottles and wooden shovel handles. This guy took this on a whole new level.
It's ok bud we start somewhere I just did this too not bad neither still get results.
I make ‘kettlebells’ with empty protein containers, concrete, & chain. They work great!
The manliest video ever
When humanity finds its self back at square one you see how important people like this man are to humanity.
Skilled smart people will ALWAYS ALWAYS ALWAYS be valuable
so true
When the age of onlyfans die this is the next best thing but this has allways been the most valuable thing
not to be "that guy" but factories and small shops have hundreds of millions of engineers and skilled workers that have been doing this every single day for the last 2 centuries.
so we already know how important they are and we're already using them to help humanity and they're not really that scarce.
so if something catastrophic happens and 90% of humanity are gone we would still have tens of millions of engineers/doctors/wokers/physicists etc. so nothing much would really change, same boring unjust ol' earth but on a smaller scale.
also he is not really a square 1 kind of guy, he uses machines built by engineers, you need engineers for square 1.
sorry for being a mood killer, it's just 11 am and i have nothing to do other than pretending to be better than other people in the comment section even if i missed the entire point and made irrelevant notes
@@thediab2732 No that's exactly what I mean I dont necessarily this guy but skilled square one kind of guyth all the way down to depending on themselves in a barren wasteland kind of guy someone who is smart and skilled will always be valuable even if its them selves that will benefit once engineering ,motors ,oil and every "modern" thing fails it will be a skilled person that would have the advantage always and dont apologize for your view points especially when the turn out to be right
"I need some dumbbells" *Makes half a gym* :D
😂😂😂
HES A TYPICAL AMERICAN DORK WITH TOO MUCH MONEY TIME RESOURCES
The amount of work, intelligence and resources it takes to make those makes you appreciate more your local gym.
Dude honestly I swear you're a bonafide genius in my book without exaggerating with the crazy stuff that you can make and do!
I have never been more satisfied and envious of one mans ability and gym equipment ever in my life.
You are without a doubt one of the best makers on CZcams. There isn’t a thing you can’t do/aren’t willing to try. I’m always impressed by your skills
Also I very much love your sense of humor
Amazing work. For someone who lifts, I do appreciate the work you put into this project.
Probably the most satisfying dumbells ever, people use the full iron plates for a reason, and supreme craftmanship, I usually dont complement people, you sir, are a master of your craft, fly high
That notch groove and weld to join all the plates was genius.
pretty common in welding
@@solmyr2 you got to understand a lot of people these days dont make anything so it seems a novel idea
Reclaimed, locally sourced, small batch, hand crafted...
Steel contains carbon so technically its organic as well.
so you could charge 3000$ for it 🤷♂️
@@Basement_CNC let’s be honest, that barely covers the labor cost here 😂
Artisanal
Gluten free
There are many gym bro's, but you my friend, you are a gym pro.
Great video 🖤
These are incredible. Building a home gym recently and looking at dumbell options when I came across this video. I wish I had the means of making a set of these for myself. I am thoroughly impressed with what you did here!
I 100% Agree. I wish I could do some of the amazing things people on here like this do. I know with time and effort it's possible, but still not likely lol
@@audiotechnika because its fk**g expensive
Concrete DIYs are always an option if you don’t want to pay but don’t mind s bit of work.
With the weight and rack weighing over a metric ton, I assume this is going on a concrete floor?
Great question. A basement or barn workout space is probably the only answer to this amount of weight
Also, did we get a cost breakdown?
Also Matthias: “Why didn’t he jump on it? Why didn’t he paint it green?”
That looks like a concrete floor in the shop...
Why anyone would put workout equipment on anything but concrete is beyond me. The weight is there but the pressure is not. If he has 8 foot pads at 4” square..you’re only talking like 16psi...concrete is rated at like 2,000psi+
Tom Brady is really making the most out of his off-season
These guys are the reason for which people can experience the facility of exercises in gym. We should be grateful.
I thought I'd watch for a couple of minutes. Watched the whole thing, great video and my hat is off to you sir!
Lifting with your own DIY dumbbells. That's some next level of alpha.
It doesn't get more old school, professional, master work and dedication than this guy !!!
I just did this at my work. I work at a metal fab shop. I run a laser and cut my plates out of remnant 1/2 plate. Dug in the saw scrap hoppers for all my 11/4 tube for handles. Then had them welded together and run through the blaster. I got 10 sets. 15-60 lbs pairs and paid under $100 for the whole set. Saved over $1,000 conservatively. And this guy is who inspired me!👍
You didn’t opt for thicker handles? I can’t stand 1 1/4
You have to be absolutely dedicated to working out to watch a guy make his own dumbells for 23mins
I need those 70-100s
Well yeah and it was a pleasure to watch. 💪🏻
@Danny Lopez I'm both🤣
yeah because im fucking jealous of him😭
And a very enjoyable 23 minutes it was.
Ending is hilarious
Too funny...after all this....lmao!!!!
When I get the urge to workout, I sit down until it goes away!
For the first time I’m genuinely grateful for the CZcams algorithm. Truly impressive craftsmanship all round 👍.
This has to be one of the best creative and inspirational presentations that I have seen in years on CZcams. You are a genius, maverick and a pioneer to anyone who is interested in exercise and bodybuilding. Well Done!! 😀👍👏👏👏👏👏👏👏👏👏👏👏
Excellent job.
Thanks!
This is the first video I’ve ever seen from this dude... Only 5 minutes in and I’m already a proud subscriber
Ditto
Dritto
same
me too.
Such a simple idea with flawless execution.
It turned out an incredible journey.
Thanks for the ride.
After moving all those weights several times I would have called that my workout and never ever moved them again. 😀 Great job Justin.
For a moment I thought ‘I can make those’ - then I saw the plasma cutter, cnc, metal band saw and other metal work tools and I realised...buying these is probably the cheaper & safer option for me 🤪. Great video!
That table alone is about 3 grand.
I was thinking the same thing. 😂😂😂😂😂
I love it. I've been in the same boat and welded some hub grips out of exhaust pipe scraps and 1/4 round stock. This was like an epiphany and pretty much built my own gym out of stuff at the house.
This is the most incredible craftsmanship I have ever seen.
Wow...the man literally have a factory in his house....what a genius though...excellent work

ya but the title.. ... dumbbell set from scrap metal... .. lol
factory? he lives on a farm . i think most farms today have a CNC Plasma in there garage so they can make there own parts for there tractors . i seen a lof of farms on CZcams and they have a CNC Plasma and you acting like them CNC machines he have for steel and wood cost him $100k or something
Making the dumbbells was the easy part. Excercising is hard.
Are you for real?
@@biscariot1074 its a joke ofc
Ariat chose wisely to sponsor you. American craftsmanship at its finest!
One of my favorite CZcams videos of all time !
wow cool project so many techniques well done

We need a barn deck update vid! But still, thank you for the content you bring out. Allways fun to watch!
This is literally grandmaster level of multiple skillsets. Unreal
I think it cool ! Home made construction ! Home made metal things good for every real men! My congratulations from Russia !
This isn’t only a good idea, the editing, commitment, and tone of the whole video just makes it so good
i was saddened by the fact he didn't make the weight bang-on instead of being off by 1/2 lb............he has the shop to make it perfect but didn't follow thru perfectly imo
This dude is a Legend
Isn't he just the best!!
This is my favorite channel on youtube. Your builds are amazing
Worked 20 yrs in metal shop built many dumbbells and gym equipment from scrap. Great idea!
I wish I had 5% of your craftsmanship ability
czcams.com/video/N9ClSl3saak/video.html
My goodness you thought of everything, the details an time invested to save a buck absolutely amazing. You should definitely continue this project stuff. Love the plasma tool you have. Grate video.
he could've thought a bit more and weld weight where it needed more and grind it of where it had too much to get basically 0.1lbs of error, but all in all great job
@@tonibaloni12 why? we are not robots and wont even notice the difference nor will it even impact any strength gains
@@user-tr2dh4xx6u ong bruh thats just over the top tbh. You'll never notice unless its more than like half a pound
Only thing I could think of is the knurling for grip!
Lo único que necesito para hacer mi propia GYM es iniciar comprando una factory, para fabricar las dimebell🤗. 🤣😂🤣😂🤣
Watched this a thousand times. So in love with the machinery, whish I could have one.
They look fantastic! I still have the dumbbells my dad and I made 30 years ago.
Its so satisfying to watch nothing but scrap turn into something so beautiful
I feel like dumbbell sets are priced like doors and windows, you rarely buy new ones, and when you do, they last a lifetime. Amazing build.
This seriously deserves a subscription, from everyone who even PASSES by this video in their CZcams playlist. What an effort! Super impressed, Sir. *salute*
instead of staying at home complaining they are too expensive never knowing when the prices will go down or when scalpers will stop their scummy practices... THIS guy actually did something about it.
Or an easier option is to adapt and stick to calisthenics.
Bcz he had access to such equipments, which otherwise was not possible.
Man the amount of work you put into your projects is crazy. Thanks for sharing with us and for inspiring me.
That’s seriously impressive work and dedication to the gym.
This came out so cleaner than I thought it would
I'd highly recommend adding some diagonal bracing on the dumbbell stand. There's some clear side to side movement at around 22:04, and that's with the rack not fully loaded yet, and just a light force hitting it in the most optimal direction. I fear that if you accidentally walk into it from the side with some force, it'll just bend the legs or snap the welds and come crashing down. It's not that I don't trust your welding skills, it's just a lot of weight, which can exert a lot of force. Front to back it's absolutely fine, side to side is a bit iffy.
Other than that: A seriously impressive build. I first thought you were joking when you said the weights were getting powdercoated, but I get why you did it. The end result is amazing.
I agree completely. As much as he typically over-builds things (and I mean that in the most complimentary way), I thought that the rack, especially given the amount of weight it would be holding, looked flimsy.
I had the same concerns, and was ready to add cross bracing when I was building it. In that shot when it's moving, there were only 2 legs on the ground because the angle came with a slight radius to it. With the weights on the rack and all five feet on the ground, i couldn't budge it. But I totally agree, I had the same "folding" concerns initially when I started.
@@rainfallprojects501 awesome job! I can be overly paranoid about stuff like that sometimes, especially when a crushed toe is a possibility. LOL
@@rainfallprojects501 Thanks for that reply. I had the same concern. Great project!
It's videos like this that make me wish I had or had access to a machine shop along with the skills to do all this. I love building DIY equipment but can be highly limited when only able to work with wood. Superb job on all of this! Loved watching the entire process.
I’m a hands on kinda guy who recently got back into fitness.
You already had me at making your own dumbbells.
But that montage at the end?
Auper well worth it.👌
These men that do this work are like that blacksmith's that create all the weaponry for the knight of old. I rack weights all the time but never think if the work behind the rack itself, thank you for the hard work you do.
This is now my default video to send to people who think Americans are fat and lazy. Great work and fantastic video!
Why would a video of a single individual somehow negate the general population statistics?
Piñata Oblongata what a fun guy this guy.
@@bailey2829 I was going to explain how it was a genuine compliment, with some implied self-denigrating hypocrisy for a dash of comedy, but I think your response may be more effective and succinct.
Always instinctively cover my eyes when he starts welding 🤣🤣🤣
Probably one of the best videos I have ever watched on CZcams 👌🏻👏🏻
I'm in love with those dumbbells
This is what I try and instill in my kids...when you put maximal effort into something your hard work has more intrinsic value than the money that was saved.
Everything about this guy is so impressive! Skilled! Talented! Creative! Work ethic! And now we find out he was a decathlete (the most impressive all around athlete there is) who also beat Ashton Eaton!! Give the rest of us a chance somewhere!
He's a genius and funny man. I enjoyed every second of this project.
LIGHT WEIGHT, BABY!!!!! RONNIE WOULD BE PROUD, NICE WORK
Hahaha here is some funny math for your cut length= “here to moon and back 3 times” (I.e. 1,433,400 miles)....
At a CNC cut rate of 1inch per second (very generous here).... it’d take you 2879 years to cut that much!!
I immediately thought the same thing- I hope he was joking lol
YEAH!! Haha, with some generous numbers for the dimensions, the cut length was probably closer to ~1540 feet or 0.3 miles.
@@masonmills8140 Well, pad it up to 500 plates ,with a way padded 3 ft. diameter for the sake of easy calculation, that's 1500 ft.

Awesome project. Also you’re the only channel I will watch adds on. Your sponsors are lucky to have you.
God Bless This Man For Making Weight Dumbbells,
Gotta love watching a craftsman perform his/her work. Awesome!
That area in your house with all the plants is awesome. Good video too.
me watching this video thinking i have the machines to make them
Go for it bro...
Did you consider going with a hexagonal shape on the plates? You could get even more out of that metal sheet
I’m guessing it was probably easier to calculate the weight to diameter increase and lay it out vs trying to match up oddball hexagonal sizes next to each other
@@rabajr911 any modeling/calc software can calculate this for you automatically.
@@leefhead1 Yep, given how well we know the weight of steel, and that we are talking about a fixed thickness for each plate, all you'd need to do is solve for area. No doubt you can tell the software to draw you a hexagon with a given surface area.
And the weights won't roll away 😆
The round shape looks traditional though. And you can still do your renegade rows, you just need a stronger grip.
I’ve made every excuse not to clean my basement to make room for my home gym. This guy literally made the gym from scratch. Those are glorious dumbbells (and rack and benches). Promise yourself a huge prize when you can bench press the 100s.
Wow. I’m thoroughly impressed and amazed! Great job!
When I was a kid my dad filled different size coffee cans with cement and stuck a metal pipe in them to make barbells and dumbbells
this is the manliest thing i've seen on youtube in a long time
I couldn't even skip the ad. You're amazing
