- A rock tumbler is a machine that can easily polish your 3d printed or metal parts. I wanted to have one for a long time and it was finally time to make one.

It's so weird hearing your native language. It almost sounds like English sometimes which makes it intriguing. I understand you even though I don't, haha. Love your videos no matter the language!
Thank you for choosing your language. It’s so refreshing. I don’t understand a word, but that’s why subtitles exist (I know making them is time consuming, so thank you for the extra effort). Although I don’t understand Dutch, you sound so much more natural and your English is perfect. Please continue in Dutch
I have a knack for foreign languages but this video I needed none of that.
If you are watching this type of video, language is not a barrier.
I will be trying this setup very soon, and thank you for your ingenuity.
Wow I didn't know NoHo Hank makes project tutorials on youtube. Really great!
I'm always amazed by your ingenuity. You incorporate wood, metal, 3D printing and electrical components into your cool project. Your skills are incredible!!!! I can't wait to see the next episode.
Awesome tumbler design, but you should add water and more sand. The sand as it is while grind on it self and eventually create a fine dust that should not be inhaled as it will cause silicosis in the lungs. Water will help the grinding and also prevent the respirable quartz dust.
Eerste video die ik heb gezien van je! Iets wat ik zelf dus ook wil gaan bouwen! Mooi uitgelegd en ga je meteen volgen! Heerlijk om naar te kijken!
I don't care what language you speak, your work is always awesome and nice designs too. Keep it up, sir!
Although I don't know what he's saying, I feel like I can understand what he's saying based on the video.
Great video by the way.👍🏻
Ha! that's nice to hear! otherwise you can always turn on the subtitles ;)
Nice idea, I'm impressed and will try to make one myself, I've heard clean cat litter is a good polishing medium.
Thanks! yeah, the clean stuff is definitely the way to go
Most cat litter is just bentonite clay.
Bentonite is a 1.5-2.0 on the mohs scale of hardness.
Most of the rocks you would be polishing such as agates or Jasper will be around a Mohs hardness of seven.
So using cat litter clean or otherwise as a polishing medium will result in you turning bentonite granules into bentonite powder.
Which most likely will do nothing for your rocks other than to make them slippery on the outside.
I've used a few thousand tons of bentonite and I would never use it in a rock tumbler.
I would just buy the proper Rock tumbling grit.
I read about how to make an industrial tumbler out of a rear axle of a big semi truck with the rims and tires in place. You want to cut an opening in the highest part of the rim to load rocks. The article said a cover is not needed but I always thought if I was going to do one I would have a hinged door sealed with inner tube rubber. The idea is to set up a motor geared down so the tires rotate slowly and all the rocks stay in the lowest part of the tire at all times tumbling over each other. Each tire can hold about 100 lbs of rocks and you have 4 tires going at all times each one with a different grit. Always use the same tire for the same grit. You rotate the rocks once a week and you have 100 lbs of polished tumbled stones each week. I have been wondering if you could use quartz sand as grit for the first stage to do the rough rounding off? I am posting this on all videos about rock hounding to spread the idea, if this is you channel and you do not like that let me know. The fact that the tumbling will all take place in a rubber tire should help keep the noise down. The rocks should never touch the rim. I have suggested to people that they make a soundproof shed just big enough to be practical so the noise will be minimized. Plus the rubber in a tire is thick and should absorb a lot of the noise. Also you should have a small fan on the motor to keep it cool. A high quality motor will be a must as it will run 24 hours a day. I am no expert but with the proper gearing the motor should not be under too much stress. I would sell the tumbled stones. Once tumbled, you grade them by quality and type. Some would be really valuable. I bet you could average $10 usd per pound with just good found material and more if you have high grade material. Definitely not for the weekend rock hound but if you sell stones or want to, what a cheap way to start. You could tumble other people's rocks for a fee or shares too. You could make one with car tires for a smaller scale operation. There has to be a lot of people with 30 year in the making, 3 ton pile of rocks out behind their house. With this they could see results from all that collecting.
I can't believe all the babies on here commenting that they're unsubscribing because the videos aren't in English any more. The subtitles are fine, and Dutch is such a great language to listen to even if you don't understand it. Good on you Emiel, great content whatever language it's in.
Haha, I get that some people leave. What wonders me is that people complain about the content they get for free
Dis altyd vir my so lekker om jou video's te kyk en dan vertaan ek net so elke tweede woord. :D
Awesome work Emiel! 😃👍🏻👊🏻
Very nice project. I didn't understand a single word, except for duck tape! :)
That says it all. There are subtitles.
I don't know that I need a tumbler. But if I ever do, I know where I'm coming back to to learn how to make my own! Also, good pro-tip. I'm only buying over-sized things now as an excuse to buy the tool to make them the proper size. 😂
Great to hear that you got the key message 😂
Hi there Greetings from Germany. very slick Design man. I like it a lot! ForDriving Wheels against the Container you can also try The ones from a Rolerblade, as they are made for asphalt, they have the perfect rubber mixture for longlivety (If that is even a word,haha). Good Project!
Nicely done !
Emil, thank you for quality and interesting content! It was pleasure to watch you. But now I'm leaving 'cause cannot understand no more. Wish you stay creative and healthy! Bye-bye
See ya!
Great video !
Tip van deze DHZ_Flip: Paar postbode elastieken ipv de ductape ;)
En wat erg goed werkt, in mijn ervaring, is straalgrit of aquariumgrind (de kleine zwarte)
oh thanks, dat is zeker een goede. Het aquariumgrind ga ik eens regelen. Zand is niet zo'n topper
Tank you
never needed a rock tumbler, still awesome video.
I wonder how long it will take me to fully understand you (right now I understand almost everything at 0.75x speed)
dank u voor de video!!
Heb je een boodschappenlijstje hiervoor?
eey eey. vraagje welke motortje heb je hier voorgebruikt en welke wieltjes om hem te draaien
verder heel moi filmpie
Cool, it looks like it could also be a handheld concrete mixer.... but I can't think of why you would want to do that.😅
You don't believe there is a market for handheld concrete mixing? What if you are out and about and need to mix some concrete? how are you going to do that?
@@Thepracticalengineer Je hebt gelijk. 🤣
Hi, have a try with complet dry Sand( Quick go in the oven à 120 degres celcius). It will be much more efficient.
Thanks for the Idea.
Thanks! I will
@@Thepracticalengineer i'll try to do one with my drill, i have some piece to zinc plating and powder coating.
That’s awesome for deburring parts. Maybe polishing too. Haha! Another pro tip... “Buy a Lathe”. Yes!
Sneaking the tips in there where I can 😂
i feel the speed is too limited. the barrel will just slide when the belts move faster
Leuk! Misschien werkt het ook met glasparelzand als je dat kunt vinden.
Oh dat zou best nog wel eens kunnen inderdaad
Hallo
Can you please tell me what motor did you used?
Any specs?
Are all your videos in dutch now?
Yes they are.
i like that !
Hallo, wo bekommt man Zahnriemen, Zahnriemenscheiben und diesen Motor?
Heb je eventueel een lijst met benodigdheden en waar je deze hebt aangeschaft??
Nee helaas dat heb ik niet meer
I see a lot of complaints that you're not speaking English. That's a shame cause this is a great video regardless of the language spoken. Subtitles are pretty good (one mistake I caught was "grid" instead of "grit") too. One more like and subscribe here.
Thanks! That's nice to hear!
Great video as always, and appreciate for you taking the time to make the subtitles, I know the work it takes ;)
Just one think, in your subtitles some times appear the time of the subttitle along with the subtitle himself, like min 3:51, if I remmeber correctly its because you missed the ; (dote with comma).
Hope I help ;)
Thanks for the heads up. I'll check it out.
Yeah it's a pain. But it's worth it :)
Mooi Emiel. 😉 ik heb me laten vertellen dat kattegrit ook werk. Bedankt voor dit project.
Oh nice! Goeie! dat wist ik niet. Ik heb me wel laten vertellen dat je dat beter niet tweedehands aanschaft, maar ik weet niet wat daarvan waar is 😂
Tweedehands zou zelfs beter zijn door toevoegingen van Ammoniak etc. 😜
Loved your videos when they were in English. I use CZcams as background when I work, so I'm not able to read the subtitles. Great content, I really hate to unsibscribe.
Time to learn some Dutch!
Great stuff! where did you get your motor, pulleys and belt from?
Its all from ali express
@@Thepracticalengineer would you have a link to the motor please?
Just curious if we have gone away from English videos?
How to make a rock tumbler in a day. . . . . . . . providing you've got all the tools i have! 😂
If you don't have this basic level of tools, you need to reevaluate your life.
@@SpicyTexan64 You need to reevaluate your life if you believe that was a normal comment. 😎
:))
Precies wat de doktor voorschreef.
Super vidéo un régale a regarder :)
Serait-il possible de faire une trappe à poule télécommandée?
Can i hire you for prototype work and how much would you charge if yes; for potentially 50hrs + self purchase of needed materials. Prints will be provided.
Hey, yes that's possible. Send me an email through my website.
Hey Emeil! why are you videos in german now? i cant watch them anymore :(
its dutch not german
Hi ben you can set the subtitals by the video
Its a pity to hear that you can't watch german videos. Luckily mine are in dutch. Enjoy!
@@Thepracticalengineer LOL
He Emiel, waar heb je die elektromotor vandaan gehaald? En loopt die direct op 230 v?
Hierzo: www.aliexpress.com/item/33031169550.html?spm=a2g0s.9042311.0.0.27424c4dCCfrU3
Hij wordt wel best heet tijdens gebruik, maar dat heeft vooralsnog geen problemen veroorzaakt.
If I was to modify this for a 5 gal/20 l bucket would you recommend I get a stronger motor? And if so how much bigger?
The main challenge is not the motor but it's the friction between the rollers and the barrel. Maybe you'll need to make gears or something to move that amount of weight
@@Thepracticalengineer Thank you for the tip!
Wat voor soort motor moet je gebruike ?
Dit is een kleine ac gearmotor van aliexpress
@@Thepracticalengineer bedankt voor u reactie 🙏
Geweldig ik ben een edelsteen tumbersteen
hm... Im German, speak English and a bit of French. I still understand enough to lean new skills and a new Language ;) Also it needs a bit more concentration but that should work :D Thanks for your awesome content 👍
Thanks! That's great to hear! Learning a new language is always good
will you ever upload English videos again
I believe he said that he's switching to dutch because it allows him to be more free in his thoughts. I think it was like 3/4 videos ago he explained why.
Hey, My regular videos are going to be in dutch from now on. I do have subtitles though. I am planning some English things in the future but that won't be in the next few months.
@Alexandra: thats right, it was in my v8 solenoid engine video
Mini Cement mixer😂😎
Met welk programma maak je eigenlijk de template's?
Hey Marc, ik teken alles in fusion 360. Ook de templates maak ik hierin door een 2d werk tekening van de onderdelen te maken
The Practical Engineer Top, ik zal eens kijken of ik dat kan downloaden. Ik deed altijd moeilijk met Carbon papier. Template op het werkstuk plakken is natuurlijk veel handiger, dat ik daar niet eerder op kwam.
Misschien heeft rivierstand met wat water een beter resultaat.
Je hebt ook speciaal polijst en schuur grid maar dat heb ik eerlijk gezegd nog niet geprobeerd..
Why no more English? I used to love your videos but now I just loose interest trying to read along. Still love your content
He said making videos in his native language allows him to be more spontaneous. He doesn't have to think as hard to say things, so he can just say what he thinks immediately.
where can someone find a motor like that ?
I bought this on aliexpress. Search for ac gear motor
Wo ist dein Oreo-Spender, JUNGE?!? 😁
My dietist told me to remove it from the workshop
@@Thepracticalengineer oh okay, hopefully you achieved your (your dietists) BMI-Goals 😅
Have a nice time during the lock down!
Pobló en español por favor excelentes videos
Thanks!
bedank beste
Baffles are too big and it could do with running a tad faster.
Wow
Thanks!
Pls next time we want in English ...Thanks for video
Please make English audio videos
géniale .
Thanks!
HBM verkoopt het "polijstspul" wat je nodig hebt :www.hbm-machines.com/producten/polijsten/polijstkogels-polijstennen-en-polijstsatelieten
Nice thanks!
WHAT?
Not a ROCK tumbler. Love the beefy pulley and belt, but the duct taped barrel might last a week before it leaks all over the motor, if it even turns. Poor engineering.
Please in english again...!!
Why not english?
I still like your videos but reading english is a bit more difficult (same on the channel from Mastermil82).
Zipped through the video and watched what I liked and found interesting.
I haven't done this before and I feel very sad about doing it because I like your content.
The zipping through/reading instead of hearing from somebody you know who talked english in his videos before makes me feel sad.
Sorry. :/
I make them in Dutch now because I enjoy it more that way
I can't understand what he is saying its definitely not english.
Builds rock tumbler but doesn't tumble rocks ...
I can't understand your accent!
Sorry, going to have to unsubscribe. Can't do the Dutch with subtitles thing.
Plz english😂
Erster
Wunderbar! Did you like it?
@@Thepracticalengineer sure! :) I never could make it myself but it was very interesting to watch even though I understood nothing 😂
Not doing English speaking videos anymore? I've had to unsubscribe 😔
Talk English please
I liked your vids but not anymore
Sorry that my free content changed
This is just too difficult to follow with the subtitles. Sorry, but I’m un-subbing.
