Homemade rock tumbler build overview.

[@PEACErocksandgarden]

Well done dude! 100 % degree you don't need high-end expensive shyt to fun Rock work

[@kengensjewelry]

Great stuff! I can't wait to see what else you make and build.

[@bricepatterson4197]

Could you add a link to all of the individual pieces you purchased?

[@chaecoco2]

I had an "aha" moment watching your video. I couldn't understand why your jars were rotating so slowly, when by my calculations your drive bar is rotating at around 308 rpms? Then it dawned on me you actually have a second pulley system going with the diameter of your drive shaft and the diameter of your mill jar. Now I got it. This is a great build. The incorporation of the motor fan was a great tip. Thanks.

This is amazing ! I love it😊

[@austinearnhart847]

Right on bro! Dope

[@jayoheyo9750]

so cool ! im about to start building one for steel hardware for plating..

[@rachaelb9164]

A parts list would be awesome. I’m hoping to build something like this. Right now I’m borrowing a friend’s giant lortone about this size actually.

[@WisconsinRocks]

Would love to see the parts list. Mostly curious what pulleys you used and what the rpm of the actual barrels ended up at. thanks!

[@wheresthepudding946]

I might use something like this setup to slow down my current tumbler because its twice as fast as i think it should be in order to get nice results..

[@Shazzamm1971]

I’m running one that uses a 1/8hp motor spinning a “40lbs” barrel with a loaded weight of 68.2lbs pulling only 3amp at 22rpm. The FLA is 3.5A. Did I mention the new Dayton TEFC motor runs at 40C… what is your amp draw and motor temp?

[@rockhound_and_down]

I think this motor is 3.2 amp 120v and 1.5 240v. I have outlets for both in my garage so i can use 240v. The temp never gets over 105*F on the hottest part of the motor. The rest of the motor is room temp. I do have a small fan on it but i dont think it needs it at all.

[@johnnynephrite6147]

use some rubber tubing from the auto parts store for better traction on the shafts.

[@kcrummel6873]

Where did you get the marathon electric motor? I'm looking for one like that.

[@stripedbassnut]

Would making the 12" pulley smaller make it run faster? I'm looking for about 66 RPM...

[@8000-f6z]

If I remember correctly you need the barrels to go something like 33, or 35 rpm, but you should verify that. There is a sweet spot to make them tumble. Too slow, and they slide, and too fast I think they break each other.

[@stripedbassnut]

@@8000-f6z I would be using them for something else besides rock tumbling...

[@dreamlookautodetailingauto3353]

Makes it run slower. Running a little bigger pulley on the motor end will make it run faster. Either or...also, 66 rpms is too fast. Rocks can break.

[@rockhound_and_down]

yes. It would increase the rpm to go to a 8" pulley. These barrels are recommended for 22 rpm which is what the manufacture suggested for this diameter. The smaller barrels do need to go faster. 50 to 60 rpm is what my 3lb harbor freight spins at.

[@kcrummel6873]

Does your motor run hot to the touch?

[@kcrummel6873]

How far apart is your roller bars?

[@kcrummel6873]

Do you have a parts list for your homemade rock tumbler?

[@saeed2r]

Where did you buy barrel ?

[@canadiangemstones7636]

That electrical tape will come back to haunt you, other than that great build!

[@rockhound_and_down]

Yes it will.... And it did. It just came off like 2 days later. I found some rubber hose that slid on the 3/4" steel real nice so it now has some thick rubber and it hasnt even started wearing and its been months now.

[@jacknife10000]

Cant you just use a variable speed controller to plug the motor into? Then you dont have to worry about pulley sizes

[@poa2.0surface77]

Simple answer: No. Complex answer: Yes... If you can match a motor to a speed controller. Problem is that there are so many different types of motors and different types of speed controllers, and everyone selling something omits parameters and/or allows 'tolerances' to the specs they provide, all in the hopes to make a sale and that you won't return the item. I've been effing around with orders and returns for 7 straight weeks now...

[@bigpapaj9165]

You think 1 hp 1725 rpm motor is to much power?

[@ianbottom7396]

If you don’t need the extra power the cost of the power will quickly chew up any savings from not buying a smaller motor

[@rockhound_and_down]

I think the amp draw on a 1hp is too much. Its like 10amps i think. This 1/4hp is 3amps. Much cheaper to run and cheaper to buy. It will easily spin up to 12 of these barrels with zero effort.
