- Components:
- Salvaged 1/5hp AC motor from a whole-house exhaust fan
- 4 pillow block bearings ($9.95 each on eBay)
- Fan belt ($9 from Farm & Fleet)
- 3/4" FIP black iron pipe ($6.50 for each 2' piece at Menards)
I had to grind 1/16 of an inch off the circumference of each end of the iron pipes to get them to fit inside the 1" bearings. I went through two bench grinder wheels doing it. Wooden 1" dowels would be a simpler, easier solution.

possibly the best youtube videos (part 1 & 2) I've seen in a LONG time!!! Thanks for sharing...
LOL. "Too fast for this country boy." Oh my gosh, this video is so dang funny! This guy needs his own show on the DIY network! Re: the tumbler: wow, this is quite a step up from the Mark I. You've gotten ambitious since the coffee can prototype! The water cooler jug is a stroke of genius. What are you going to do with all those rocks? I don't think it's about the rocks anymore. It's about the machine.
Nice.. had a good laugh when u put the rocks in the jug (thanks I needed that). well done:)
Great suggestion, Ranger Jack!
Just make sure there's adequate airflow to keep ya motor cool.
I love the idea, i used a 240V servo motor, and it did wonders. thanks
i love these videos by these ingenious guys solving complex problems with simple solutions. Wath the video of the guy who made a sphere grinder with 3 conical abrasive cups and rubber bands.
Hey, it works! So, well done! But one suggestion - it will run more efficiently (less slippage) if you reverse the spin, or put the drive belt to the other rod. Because of the spinning action, the rocks and media usually stay bunched up on one side of the drum, so if you can get that weight over your drive rod, you'll get more grip. Otherwise, it's a beaut!
Great video, interesting, helpful and funny. Thanks for sharing..
you could add a large pulley at your pillow block so your motor can run closer to it's normal speed while slowing the barrel down.
Great video! Love the accent! Keep it up, yo! I want to see the finished product. Hopefully I'll be tumbling some rocks soon :)
Not a bad idea overall,but you have your fan-belt installed wrong side out.Also you could eliminate two of the pillow blocks and use two industrial casters installed upside down,thus needing only one "axle".
What kind of pulley did you put on the 3/4" black pipe ?
i wonder how long it takes to polish if you arent using all 4 grits?
dude this guy is awesome!!!!
is the belt on backwards?
I like this video. I know it's older, but works great.
I do have a problem with the one I am building. HOW DO I GET A 1.060 IN. DIAMETER BLACK PIPE TO FIT INTO A 1.000 IN. BEARING BLOCK?
Do I have to find a machinist to polish them down?
Thanks!

You're not going to fit that extra 0.06" into that bearing. You have to machine it down to 1.000" but it's likely more expansive than to just buy a 1.000" standard than to make someone machine for you.
Cool idea if I did something like that I make a sound proof box with to fans still cool idea
👍👍👍
anyone else notice the fan belt is backwards? notches on outside?
i wanna see the rocks afterwars make a video plz
is this guy for real or is this his "stage persona"??
if you boxed it in, it would be quiter and no so noisy
flat axle. v belt turned inside out is....wait for it... a flat belt!
Running a little fast.
Still too fast.....Lots of variables but 50 rpm barrel speed is a good number to start with.
your using my design
I think it would have been much cheaper to have purchased a used treadmill.
Why don't you put them there rocks back in the stream you got them from and let nature do its job. its water cooled and gravity .just sit there on them sack of seeds. you never left the farm
Mmmmm K
