Absolute best DIY system on the internet. Very great for the common man!

[@DesignBuildLift]

Thank you so much for the kind words!

[@shiwakuseven5859]

I made a pair of 60 lb dumbbells after watching this video. Thanks for the info and the idea!

[@DesignBuildLift]

Thank you! When I hear this, it drives me to continue making videos! Many more videos on the way soon. Right now I am in the process of shooting and editing... Happy Lifting, my friend!

Found your channel and built my own over the weekend. Finished up a chest workout and bicep workout over the last 2 days with these! Amazing. Bought 2 different size nipples to accommodate more weight ranges! Amazing!

[@DesignBuildLift]

Awesome! Glad to hear it!!!!! Thank you for supporting the channel!!! 🤘🙏💪

[@P10101G]

Subbed cause of this video. I built these over the weekend. Cost me ~$42 for the 12inch pair. I believe they are still worth it if you have the extra weights. I did add a piece of pvc between the pipe and weight holes for a tighter fit. Not needed, just a personal preference. The work great and no stabby stabby. Thank you for sharing.

[@DesignBuildLift]

That is awesome to hear!!! Thank you so much!

[@marklee6701]

I like the concept. You could cut the pipe for exact lengths, cut new threads and put a floor flange on both ends. Wouldn’t be adjustable but look like legit dumbbells.

[@DesignBuildLift]

Absolutely!🤘💪🙏

[@michaelkulman7095]

Great! I was thinking of foregoing bells, having priced Iron Masters, Power Blocks and fixed bells, going barbell only, or spin lock, now I'm reconsidering!

[@HeadshotUK77]

i found a pair of Reebok interchangable dumbells for cheap i just want to make the bolts longer so i can fit thicker weight theirs 4 thin weights on either side of them their half inch thick, i can get a 5 kg weight on either side their 2 inch thick, I also love how you made these amazing

@@DesignBuildLift That's awesome man! I'm not too familiar with the parts used in this video but it seems solid and really if you have fat gripz already is as easy as it gets. Planning to try and scoop up a few hundred pounds of "1 sized plates now. Thanks again for the idea!

@@DesignBuildLift I think somebody should make a solid proffesional machined version because the Idea of having an assymetrical flat bottom DB is awesome in itself. I am not sure I would even trust red loctite on the flange side with 100+ pounds over my face! I want a one piece machined solif or welded like a LOADING PIN, which are pretty cheap but I would want 18" at least. Good Work Man!

[@austindeshazo1428]

Great idea!

[@emmanuelhud1]

I know this video is old. But hopefully, I'll get a response. Here in the UK, we have 1/2" and also 3/4" even 1". Why did you use 1/2"? Wouldn't it be better to use a bar/tube that is a tight fit for the weight plate hole? So it doesn't move as much. I understand it will make the grip girth bigger, but isn't that why you put the pvc in there ? What do you think?

[@DesignBuildLift]

Hello! More details here: diyfitnessclub.com/projects/blog-post-title-one-k9zas However, here is something missing from that article: not all my 1” hole plates would fit on 3/4” nipples - because most 3/4” nipples have an ACTUAL width of slightly larger than 1” ). This was a primary reason. However, you should use whatever works for you. Cheers! To see the demonstration of them not fitting, watch this video here: kzbin.info/www/bejne/bZvVaJ-gfMmAZ7Msi=V4uEPirn0mD4z8AK Go to 2:14 of that video. 🤘🙏💪

How's your grip on the dumbbells using the EMT conduit wrapped in tap? How does it compare to knurling on a commercial dumbbell? I'm thinking about making some fixed weight dumbbell handles handles and wrapping the EMT conduit in anti slip tap; the kind that is used for traction on steps.

[@DesignBuildLift]

Great question! Anti slip might work. Have not tried it….not sure how it would hold up though. Some other options to consider: could add grip tape, spray truck bed liner on the EMT, or perhaps add some rubber grips on the EMT (got any used bicycle handle bar grips?)….my 2cents: whatever you do - do it on the cheap. If not done cheaply- then at a certain point it just makes more sense to buy instead of make. Thank you for supporting the channel! 🙏💪🤘

[@Romulux]

Considering you're going to be touching the grip surface a lot, I'd use something meant for that, like grip tape for a tennis racquet or golf club. Then you dont have the potential danger of leeching chemicals from the electrical tape, and the grip is replaceable.

[@luluandbear7932]

Great video. I subscribed and turned on notifications!

[@DesignBuildLift]

Thanks for subbing!

[@johndrapeau]

Maybe i missed something, but the threads on end of handles. , who put them there?

[@DesignBuildLift]

These plumbing nipples are purchased from big box USA Hardware stores with the threads already on them. Of course you could cut/thread the pipe yourself,too! Thank You for supporting the channel! I appreciate it! 🤘🙏💪

[@tylershine3012]

Awsome idea, do u know where I can get the plates at thanks!

[@DesignBuildLift]

Thank you!!! I appreciate it! Not sure what country you are in, but if in the USA- Your best bet is to buy used plates from Facebook Marketplace, Craig’sList, or OfferUp. Alternatively, you can buy some new plates via my Amazon Affiliate link: amzn.to/3FsPJVF

[@tylershine3012]

@@DesignBuildLift Thank you so much!

[@littleBrownDwarf]

A pipe cutter would probably be the cleanest way to get a nice clean, square cut on the EMT conduit, rather than sawing.

[@DesignBuildLift]

For sure. But I used what I had.

[@anthonyanthony284]

Two questions, firstly since the handle's hole are bigger than the bar in the middle significantky, does it rattle when lifting? Second, when using heavier weights, does the clamp really hold tight?

[@DesignBuildLift]

Since the 1” handles fit easily on the 1/2” nipple (Fact: 1” handles will not fit on 3/4” nipples), this also means that the handles do slightly “move” while exercising (i.e., there is a “click” when conducting movements). If you have a good spring clamp the plates shouldn’t move. All this being said, obviously store bought solutions are generally going to outperform this hack in most ways.

[@thecoolguy365]

Where you get the 10lb plates. That's a great dumbell creation.

[@DesignBuildLift]

Thank you for supporting the channel! I really appreciate it! I bought the large majority or my weights second hand via Facebook Marketplace or OfferUp 💪🙏🤘

[@no-handles]

genius!

[@raptorsrule4]

Could I just add the flange to a regular spindle dumbbell?

[@DesignBuildLift]

No. The threading is not compatible with one another.

[@michaelkulman7095]

I have seen people take an extra spinlock "nut" and put it at bar's end to get a flat surface and some cover the hole by welding a piece of metal onto it or a small plate off center or a large washer off center. Also I've seen someone sandwich wood around a spin collar. All ways to try and make spinlock dumbbells have one flat end. All those seem to work but they aren't so pretty...

[@tobikramschuster645]

Love the idea. But why 1/2 inch and not 3/4 inch pipe? Because 3/4 inch pipe has less space between the plates :)

[@DesignBuildLift]

True - most 1” plates would fit tighter on 3/4” nipples. However, many of my plates did not fit on 3/4. Most of my York plates especially were too tight. Cap and Sports Authority plates mostly fit. Anyways- this is why I primarily chose 1/2” nipples for the video. Of course - I encourage everyone to customize these projects to best suit their needs. Thank you for your support! 🙏

[@kabukiQUE]

Hello, has anyone experienced any issues with these yet? I’m afraid of things breaking

[@DesignBuildLift]

Not that I am aware of…but it’s always a possibility when it comes to DIY gym equipment. If concerned- buy - don’t DIY.🤘

[@miltonjimenez7312]

How quickly will they rust? And is there a way to prevent them from rusting like some type of paint ?

[@DesignBuildLift]

Rustoleum spray paint can prevent the plates from getting rusty. For nipples and other hardware, buy “galvanized” versions (not “black iron”) from your hardware store and you will never have to worry about rust.

[@tylermoran1826]

What do you think the max weight the pipe nipples can hold? If I were to slide a steel rod inside the pipe could they hold more?

[@DesignBuildLift]

Good question. I put 145 LBS on a 18” plumbing Nipple. Didn’t flex at all. Strong enough as is. 🤘🙏💪

[@eyaadkhushizafar8034]

@@DesignBuildLift i use 490 pounds each dumbbells' for my exercise and for big exercise like dumbbells' benchpress i use upwards of 500- 850 pounds or even for a 1 rep i use 1500-2000 pounds . So do you think it can hold that much

[@DesignBuildLift]

@@eyaadkhushizafar8034 2000 pounds? Wow that is a world record!

[@goldmanasable]

Curious why no just do flanges on both ends

[@DesignBuildLift]

Great question! You certainly can do it that way, too. However, I found that when trying to unscrew the top flange, the entire nipple would turn and the bottom flange would be the flange that gets unscrewed. In other words, turning the top flange would unscrew the bottom flange. As a result- this was not ideal for what is supposed to be a quick-change design. In my opinion, having two floor flanges works better for more “permanent” dumbbells (not “quickly adjustable” ones). Thank you for supporting the channel! I appreciate it! 🤘🙏💪
