How to make a Rock Tumbler Ball Mill 

I'm working hard to grow my channel so hit that subscribe button before you forget!

great Idea I tried this with sewer pipe but didn't put the agitators in and gave up because it took for ever to tumble a few rocks and the result wasn't worth while, now I can revisit the set up and see what happens thank you at 73 still learning

Great design and very well executed! Thank you!

Great job. Just what I need for cleaning small batches of native plant seeds.

This is a really nice rock tumbler thank you.

Dud this is a little late but damn nice job! One of the only and actually feasible builds out there for a tumbler

Great vid man! Concise, honest, no faff 🙌 thanks. Subscribed

Nice job. Thanks for sharing.

Very innovative👍 Glad to have found your video💐

Great build. Thanks.

I want to do an all polished aluminum AR build, and something like this would work PERFECT!

This is great. No b.s. and no nonsense. Love it! Subscribing now. :-)

Fantastic video!!!!

Very cool idea! This looks like the best high capacity and low cost unit I've seen. I will try making a variation on this. I'm a little worried how the PVC will hold up to weeks or months of tumbling bigger rocks but I guess it could easily be replaced. I might try coating the inside with thick layers of rubberized paint.

Love the design. Having those wheels on their solves the problem of the end caps needing to be smaller than the jar

Brilliant outstanding wonderful 👍. Thank you so much for explaining. Subscribed like shared personalized notification.

Hey love the idea of being able to do one big bin or multiple smaller ones! Thanks for the video! I’d love to see some content on diy media alternatives for different grit numbers! I like the idea of ball bearings - can you show a video on how well this works???

nice tumbler..

Great video.

cool...new sub!

Nice, I'd wondered about using PVC pipe for the tumbler. Also, as crude as using rubber end caps might seem, they should definitely reduce the "bomb index" if something were to ignite.

Nice freind 👌👌👌🙏,

nice interesting video, I made my own tumbler too, its on my channel, great video, thanks for sharing

I thought about building one pretty much same way. I was thinking about an automotive motor, like a power window motor, but the 12v dc was throwing me off. I also thought about pvc pipe, but with screw in type cleanouts for the ends, one last thing was wheel casters from a cabinet or chair, mounted upside down. I suppose I could add additional casters if I was going to do different size ones. I think I have most of the parts just lying around here. Thanks for the video.

Just my two cents: need easy system of gearing, that is pulleys, Have found it is easy to make polyurathane belts and wooden pulleys, 5/16 inch belting, cut to length, heat ends, but joint in simple right angle jig. I needed slower RPM on drum from airpurifier fan motor. So just about any 500watt+ motor can be reduced to critical or less drum speed. 1/4 inch baltic birtch plywood. ABEC wheel bearings and 5/16 skateboard axles. i also used skateboard trucks & wheels with an 8 inch PVC drum. the poly belts are amazing.

I would love to see someone make a DIY ebike out of power chair Motors set up like a mid drive so that you can Leverage The Seven existing gears or however many you have in your back cassette and your rear derailleur as it already is because these are actually powerful Motors with huge potential with low RPMs in high torque that I think would be just perfect for an ebike but I've searched high and low and haven't found a single video yet where their used for an e-bike. Millions using washing machine motors and old hoverboard Motors but absolutely nothing using power chair Motors and I thought you might be up to the task.

Damn, that’s nice. I was just thinking of making a rock tumbler out of 6” PVC when I ran across your video. Great job. I’m not electrically inclined but I’ve seen 100 to 200 RPM dc motors on eBay. Do you know what I should look for in terms of Watts and amps? Thanks, Paul

Make a geyser pump that will pull water from 40 ft down inside a 2" pipe

Any idea what RPM the wiper motor operates at? Could a power window motor also be used or are they more expensive? I've been wanting to modify a tumbler to run multiple barrels and also wanted to run it off of a solar panel and battery.

how many hours you have this motor on? im not sure, but i think this windshields wipers motors arent made for long time work... i wanna make my own rock tumbler, and the motor is the only thing i havent now. did you try this motor for long time and works good? ty for all, and ty for the tutorial. its so good. gg for your chanel

Ok, exactly how did you get that aluminum case to break like that using the wire. It seems you performed a bit of magic. A detailed explanation would be really great, unless of course it's just a gag, then haha. Also, windshield wipers get hot when used continuously I am wondering how you managed to get around that problem? Perhaps because it's out in the yard using a solar panel for power, if it can catches on fire nobody cares? And last but not least, how well did the final ball mill work. Just wondering if it was ultimately a great success or all just for fun. BTW: I did cringe just a bit when you glued up your bearings. Nice trick though.

How did the drum hold up over time? i have access to 8" pvc pipe so im kinda curious on if its a longterm waste of time?

Would you mind sharing some details about you hooked up the solar panel?

i want to see you make those lines behind you

Make a rock tumbler from an icecream machine.

I would suggest to use a motor from a washingmachine or dryer. You can get those for free..

Do you have the plans for this or do I need toextract them from your video?? Thanks!

Cool project, but one question: Does the PVC not wear down? I had the impression that tumblers had to be coated in rubber, which is less rigid, in order to protect them from wearing down. Have you noticed any issues with the PVC?

A Tumbler for a 5 gallon bucket Need to make Black Powder

Hey mate what tyre of window winder is it old school or electric

Question: As you are using PVC do you have any concerns about the buildup of a static electric charge?

Cotter pin?

I always get a laugh out of you guys using WD40 as cutting fluid.

Do you know what kind of car that motor was for? All the motors I've looked at aren't as flat as that one.

How about a vibratory rock tumbler ?

Rpm?

This is cool but way beyond my skill level. And used equipment I don’t have access to use.
