Rebel 17 Large Professional Rock Tumbler for Adults, 17 lb

I currently have 5 rock tumblers, and this is the best one. It is large, quiet and made from quality parts. It is clearly a copy of a Thumler's Tumbler Model B (not a bad thing) with some quality upgrades, offered at a lower price. I had never heard of this brand and neither had anyone in my rockhounding club. Similar to Thumler's, you cannot buy from them directly and must utilize a 3rd party, but they appear to be a legit if not low-key company. On this Rebel model made by Xtreme, the nuts used to secure the lid were upgraded from pressed wing nuts and washers (used on a Model B) to single nuts encased in plastic that are easier to finger tighten. The axles and bearings also appear to be higher grade steel and are more robust. There does not appear to be many other differences. In fact, this Rebel model and the Model B are so similar they even use the same drive belts. FYI assembly is required for the Rebel. You will need to mount the motor to the tumbler base. Oddly, the motor only uses 3 mounting points but has four threaded posts and the written instructions do not mention the four posts at all. I am guessing Xtreme just bought generic Chinese motors that were not made specifically for their tumbler but fit their purpose. I don't see many other ways the motor can be mounted so I do not think it was to provide more mounting options. Good tumbler overall will probably buy another one.

If you are a rock nerd- definitely get this tumbler!! For the level of quality this tumbler offers - the price is worth it. Especially if you can get it on sale (I got lucky with this). It is a little bit loud, but if you have a space to put it (like the garage, separate room, or even a closet)- it's not terrible. This thing is built like a tank, although, some of the black covering does rub off a bit as it tumbles on the exterior of the tumbler. It is kind of heavy- but honestly makes a huge difference on polishing and tumbling rocks compared to other tumblers I've used. It's seamless to use one you have everything locked into place.

Quite good. So much quieter than most tumblers on the market. Things to know: unit is fairly large so consider the quantity of rocks you intend to tumble and buy accordingly. You will likely need ceramic tumbling media to fill excess space. After 4 months of use, I am seeing some wear on one of the rubber rollers. Replacement parts are available from the manufacturer.

This thing is a monster! 15lbs of Rocks in one tumbler! And they come out smooth and shiny and gorgeous. Of course you need a lot of grid for one of these bad boys! But they work awesome!

We've been using an entry-level tumbler from National Geographic (purchased on Amazon.) The National Geographic tumbler set up quickly, no leaks, and is very quiet. This tumbler offers substantially more capacity for more, and larger, rocks. The assembly was straightforward but the unit immediately began leaking. The lid & gasket both look flat, but the seal on the barrel itself appeared to be a bit "lumpy." I was reluctant to over-tighten the thumb nuts, as some reviewers have reported broken studs. However, I put external pressure on the lid with a clamp, to compress the barrel gasket. Once compressed, I was able to hand-tighten the thumb nuts enough to stop the leaking. A thicker lid and a thicker, more compressible gasket would be a big improvement. Now that the leaking is resolved, it seems to be working fine. It is, however, a bit noisy. (Think: someone put rocks in the washing machine.) Probably best to set it up in the garage or shed.

My new Rebel17 arrived yesterday and I have not yet started filling it for my next run. Before doing so I want to comment on the mistaken idea several reviewers have that this machine tumbles too slow. Au contraire, the slower speed is why I acquired it as the slow speed gives rocks some protection from bruising, fractures, and unwanted chipping as they bang up against each other throughout the tumbling process. Fast tumbled rocks are more likely to crack or break as they hit each other than those going through a slower and gentler sliding grind. We want to polish them, not punish them. I've only been tumbling rocks for 7 years and don't have the experience of some of the veterans who post videos filled with instructive information on sites like YouTube, but have tumbled enough rocks through the 5 tumblers I own to know what works better and best and what can be improved. My first 2 tumblers purchased were / are National Geo. They have functioned reliably and have produced some beautiful specimens, but even in their smaller capacity there have been rocks damaged in the process from time to time. Always a disappointment to find damaged rocks in your barrel when they've been tumbling a week. I also have a Lortone that gives satisfaction but it too tumbles on the fast side. The 3 tumblers hold 1.5, 2 to 3 pounds of rocks but I find many larger rocks showing hints of color and patterns too big for a smaller barrel. The desire to find and polish rocks can drive a budding rock hound to spend more and more time hunting, collecting, and polishing them. Most especially when one is retired, has the time, and lives in Colorado where intriguing rocks can be found even in one's own back yard. So many rocks! To process them more quickly I acquired a Thumler Model B with a large capacity barrel that has room for larger rocks. It too rotates fast but other than breaking 2 drive belts in 3 years of use it has been reliable. Two years ago I acquired the 5th tumbler, a Tumble Vibe vibrating tumbler that holds 10 pounds of rock. It is not - I repeat - not intended or designed to run or shape rocks through stage 1. Doing so risks damaging your barrel. Vibratory tumblers do process rocks faster in stages 2 through 4. A load of rocks properly and well prepared in a rotating tumbler in stage 1 will go through stages 2, 3, and 4 in a vibratory tumbler in less than 2 weeks. However there are design issues complicating the use of a vibrating system, so be aware of possible complications if you are thinking of acquiring one. For ease of use and the advertised slower speed I decided to purchase the Rebel 17 and look forward to seeing the inner beauty revealed in the larger rocks that found their way home with me. You know how that is ... And as an aside, a final thought on the question ''can God make a rock too heavy for God to lift?'' Apart from the absurdity of the question, consider God is not limited to being the singular lifter of said rock, but the lifting action that moves it. If God were a part of speech, God is more Verb than Noun.

I've had a timbler previously - one that was small, and very loud. This tumbler is KING of the tumblers. It works so well, and has a giant 17-pound capacity. I've tumbled 100-150 rocks at a time. It's also SO quiet. I recommend it highly.

This thing ruined a bunch of my treasured agates. I've been collecting rocks my whole life. Agates are my favorite. I've collected from all over the country for many years. I bought this to tumble them and make them even more beautiful. I was so excited about using this tumbler!! I put my collection inside and added grit/ water, sealed it up and walked away. The next morning I was horrified. The lid didn't seal on the tumbler and the water grit mixture was slung all over the walls and floor. A tumbler this size holds a lot of " mud". When I opened it up my agates were beaten, broken, cracked and scratched. A whole lifetime of collecting was ruined. I cried! Im a grown woman and I cried over rocks. 😆 But I had such expectations for these rocks and it took a really long time to collect them all. I reached out to the company and all they said was "they will accept my return". No apology. No option for a replacement. No box of agates offered for my loss. Just a cold reply. I shipped it back and I still haven't bought another one. My agates are now sitting in a shoe box under my bed waiting to be resurrected after being totally killed. I don't know if I'll ever do anything with them. But this tumbler and the company aren't for me.

Bought the 20rpm version for rock tumbling. It was easy to assemble and is solidly built. I like the individually adjustable legs to get the base level. It’s only been running for two weeks now on stage 1 grit but so far zero issues. I fill the barrel 3/4 full of rocks with grit and water. The motor has no issues with the load and is very quiet. A big barrel with a thick liner also keeps the noise of tumbling rocks down. I expect this tumbler to last as so far it looks like it will.

Not happy with purchase as I bought it prom AU website to be used in Australia I expected it to be 240 VAC not 110 VAX. Now I have to change the motor or buy a 240 VAC to 110 VAC converter. expected more from amazon.

Well it takes a lot of rocks to fill up this big girl, but the unit is quiet and revolves slowly. This baby is pricey, but it sure works if you want to tumble lots of rocks from the lake. I like it for fossils too because it tumbles gently. Unit came well packed and on time. Over all I am happy with my Rebel 17th. It will be interesting to see how long the motor lasts. Rebel 17 has been working for 6 weeks now, so far all good.

Easy set-up, quieter than smaller capacity tumblers we have used, accommodates larger rocks that wouldn’t fit in the 6lb tumblers, great customer service from the seller.

Very quiet for the size.
