Awesome. I also like the vertical bearing idea. I have never had a barrel leak but like the covers for safety reasons. With those and some simple covers on the outside there would be no concerns of danger from the pulleys and belts with kids around. What kind of rocks did you choose for the maiden voyage? Chuck Thanks Chuck! The safety aspect kind of grew organically while i fleshed it out. Months ago before my old tumbler broke, I started a bunch of stuff including​ Morgan Hill from luvtogrow. Lakers. Stuff from txrockhunter... I have it all back in the barrel now. Tumbling with 30 Grit and kitty litter slurry. |

Curious how a PVC barrel compares to a lortone 12 . Around here , by the time you buy pipe , caps reducer and the cover , there wouldn't be a lot of difference . Just wondering .

Nice build and I have been using PVC barrels from the start.
At least one for each stage. Never heard that before , have you. LOL
Ok, you need to tell more...what size motor you have rpm HP?
What is your plan of the RPM of the barrels?
That's all. For now.:). Carry on.

I think cap, pipe, reducer bushing and flex cap amount to about $50 per barrel at homedepot.com. buy enough for a couple barrels and shipping is free. ETA Just ordered enough stuff for 4 barrels except the fernco caps for under $100 |

Very nice Scott. Looks like a sturdy build and I like the purple! I find the side "splash guards" interesting and yet you mounted the motor below where the barrels will run. Digging the pulley set up, seems like an excellent idea.
Motor size and barrel RPM info?
If/when I get around to such a build, I want to have the different levels run at different RPMs. A faster RPM shaft/level for coarse grinding and a slower level for finer grits & polish stages.

Busted on the motor. Need to mount a cover for that too!  I wondered who would bust me! 1/6 HP. This machine is all rough grind. 80rpm. I chose this because of the performance of the previous tumbler at that speed. Very fast rough to shape. Top floor could easily be slower. I have a Lot-O and plan to next build a quartz still vibe for big rocks. |

Nice build, Scott. The PVC barrels are the way to go. Never took pictures of my latest setup, but it seems to me that the PVC barrels generate a good slurry faster, and grind faster than the Lortone barrels. The splash shields are a great idea, my big tumbler popped the cap one time. Nasty mess. captbob idea of different speeds works, that's how I set mine up. Whole thing is torn down again now for revamping, pictures by late summer I hope. Your barrel speed is 80 rpm? That should round stuff off real quick like. Russ |

That's one big 1/6 HP motor. Never would have guessed that.
80 RPM ?!! Zowie! Seriously? wow... That thing may get airborne turning at 80 RPM!
I have to ask, why so fast? I'd be worried about pulverizing rocks at that speed.

Where is that located? Multiple PVC barrels full of rocks running 80 RPM is gonna be a tad noticeable on a decibel meter.

Thanks Russ and Bob.
80rpm was the speed of the previous tumbler. It did not harm the stones and did round them fast. I do run them very full as rock volume is lost very fast.
Might slow the top tier for the 80AO phase. Will advise.
It's in the garage far from anybody's (mine included) bedroom. Lol
The real noisemaker is the freaking Covington 18" saw. Wow

Sweet safe build. Designer color and lots of capacity. Like the long shaft capacity. 1/6HP, is it 1000 or 1725 RPM ? If 80 RPM is to fast for you it can be changed to slower speed. If you do have a slower shaft on top you can simply buy a belt and pulley for ratio changes. If you have enough shaft length you can mount both ratios and perhaps just do a belt change. Or better, have an adjustable spring loaded idler like the Covington saw has for 6 speeds using one belt. I like your reasoning about using the rotary for coarse grind only. Coarse grind is always 3-10 weeks. The vibe is 3-4 days. The main reasons I use 30 RPM instead of 55 RPM is for 1) big rocks and 2) AO 80 if doing AO 80 in rotary instead of vibe. Or I just don't want to add coarse grit so many times in a week. But, you may find 80 RPM with 85% full barrel is plenty gentle but faster grind than 30 RPM with a 75% full barrel.(yes, much faster) I have run big rocks at 55 RPM by simply running one big rock with small to medium sized tumbles at 85% fill, slurry. Purrs like a kitten, grinds super quick. Grit done in 12 to 24 hours. Usually too busy to add grit daily though. Such speeds will get er done. All looks great. The splash guard design is probably going to come in handy. Faster speeds can make gas fast. Just watch when Fernco caps begin to bulge out. You could add a safety cutoff switch at the end of the barrels that would turn off the machine if cap starts to bulge shifting barrels into the switch. Mounting the bearings vertically on a post set your shafts to perfect parallel too-clever. Glad at jeannie got you off your duff and put you to finishing this long awaited project. |

Curious how a PVC barrel compares to a lortone 12 . Around here , by the time you buy pipe , caps reducer and the cover , there wouldn't be a lot of difference . Just wondering . Leaking Lortone caps is what pushed jamesp into making his own barrels in the first place - back before he joined RTH. A LOT of experimenting to make them last took him to his present design. |

Hard to tell dimensions but in the second photo it looks like the grease zerk fittings might be tough to get to with a grease gun? Mine are a pain in the butt to reach which results in not greasing as frequently as I should. After 5 years I really should do a complete tear down and replace the bearings. I think there is a 90 degree adapter available for grease guns though if your are hard to get to.

Leaking Lortone caps is what pushed jamesp into making his own barrels in the first place - back before he joined RTH. A LOT of experimenting to make them last took him to his present design. I did tumble a lot of glass and metal which tested the seal on Lortone and PVC barrels though 1dave in early days. Very rare to have any gas tumbling agate wood coral etc. The Fernco caps are a bit friendlier than Lortone caps in that they begin to bulge telling you to release gas. wigglinrocks - I did shop fittings on eBay and Amazon and greatly reduced the cost of PVC barrels. Namely buying Carlon brand electrical PVC conduit fittings. It helps if you can by a stick of used such 40 pipe from a plumbing company that will provide for 4-8 barrels. And 6 inch is affordable a very competitive. However, 8 inch pipe and fittings is NOT competitive as they are costly. 10-12 inch off the chart. A 3 foot long 6" sch 40 pipe barrel is very cheap considering you have a 35 pound barrel for about $40-$50. 40 pound barrels factory made are way more costly than $50. Lot of bang for buck. |

Never trust an engineer to design machinery for mechanic's sake. It is their goal in life to torture mechanics. In this case I am also the mechanic haha. EX Having to use a 4 inch long wrench on a 200 ft.lb. nut because the dumazz engineer put the bolt in the corner or down in a hole. |

jamesp 1/6HP 1725 @ Chuck, fourscrews removes the splash guards then grease fittings are easy.
