Review: Two Containers are Better than One - Great tumbler! I've tumbled probably a dozen batches and it's still a workhorse. I purchased the Lortone 33B because it takes so long to tumble rocks that I wanted more than just one container. Because I'm tumbling year-round, I put the tumbler in the guest room -- inside a large Styrofoam chest (the cheap kind you take on picnics). I poked a hole in the chest through which I ran the cord. While this is a fairly quiet tumbler as is - it's still too much noise unless you muffle it some way. Inside the chest - it's virtually silent. Tips: Make sure you oil it regularly as suggested in the manual. If you don't, you'll hear squeaking. If you set it up in a garage or basement, check on it daily -- you don't have to open it -- just listen to make sure it's not squeaking. If it is - - oil it immediately. The key to beautiful polished rocks is to choose hard rocks that won't grind away during the tumbling process. Flint is wonderful, as is quartz, but anything like sandstone will be gone by the end of the tumbling cycle. The other key is not to skimp on tumbling time. Don't get impatient -- add a day to a cycle if you like, but don't think you can stop a day or two short on any of the cycles without sacrificing the end result. I like to add a variety of stone sizes in a canister. Your stone will be smaller than it was when you put it in, so, if you plan to use your stones for handmade jewelry, keep that in mind. Thin, flat stones have a tendency to break in the first tumbling cycles, especially if you put larger stones in the container with them. I've owned this for over a year now and it's still going strong. I would buy it again.
Review: Love this tumbler. - I am very happy with this tumbler and have been using it for about a year. Easy, quiet, clean, good quality and good results. I also have a Thumbler tumbler which I am throwing away after one use because it is filthy (throws off piles of black rubber shreds), noisy and doesn't spin well . The Lortone is a winner. It is far superior to the Thumbler.

## Questions & Answers

**Q: What else do I need to get started with rock polishing?**
A: You will need 4 grades of tumbling grit, coarse, medium, pre polish and polish. I get all my rocks from the Jersey Shore, so they are pretty rounded and smooth to begin with. You also need a lot of patience, each of the 4 steps takes a week to complete. I am very happy with the Lortone 33b Double Barrel Tumbler.

**Q: start to finish how long does it take to do a batch of rocks**
A: From 4 to 6 weeks. Some polish faster, others take longer. During each stage of polishing we go through each barrel after a 4-5 day period and select which rocks stay back in the barrel they came out of and which go on to the finer grit for polishing. If you take your time you can get some very beautiful rocks. We use two of the two barrel polishes so we have all 4 grades of grit going at once. Just keep moving them to the next level of polishing. After 5 weeks you should have a polished barrel of rocks each week.

**Q: Besides polishing stones, can I also frost glass to look like beach glass?**
A: You can, but I'm not exactly sure how to do it. I have polished some rough beach glass using fine sand. (But then I have to state it is not genuine beach glass-purists don't approve of putting it on the tumbler. http://davesgarden.com/community/forums/t/761052/     try this gentleman's siggestions -

**Q: I want to run a rock polishing machine in an outbuilding. How safe is it to leave it running unattended? How often would one need to check up on it?**
A: Although I enjoy lapidary questions, to give a complete answer to your question I would need a bit more information such as:    What style of tumbler do you have, rotary or vibratory?    How large are the slabs? (Big ones should go into a vibratory tumbler; small ones can be done in a rotary)    What are the materials? (Rocks need to be separated by hardness to tumble polish, as softer materials can be quickly ground away or beat up by harder materials)After you have determined the above answers, you will need some grit (generally silicon carbide, a minimum of 3 grades from coarse to fine, depending on the hardness and material type), a polishing agent (again, this will depend on the materials you are tumble polishing, usually cerium oxide works well on most materials) and a separating medium (I like plastic pellets) to keep the slabs from sticking together for a nice even finish.To tumble wet (usually in a rotary tumbler), you would place the slabs and plastic pellets into the tumbler's rubber barrel and add enough water to fill it 4/5 of the way, then add the grit (coarse first; the amount depends on the size of the barrel). Tighten the lid and turn it on for the first run. The amount of time required for each run will depend on the hardness of the stones, from a couple of days to weeks. When the first run is complete, empty the barrel (never into a sink, as the slurry can really mess up plumbing systems), and thoroughly rinse and clean the pellets and the stones. Then repeat the runs, using medium grit next, and finally the fine. When you are happy with the results, it is time for the polish.Be absolutely, positively sure that there is no grit whatsoever left in the barrel or on any of the stones, as one piece could destroy weeks of work! I have barrels just for polish. The polishing run can take less than a day, again depending on the stones. Wash your stones completely, and wrap as desired!In a vibratory tumbler, I prefer to tumble slabs dry, using the same processes as above without adding any water, as I find slabs tumble polish more quickly in a vibratory tumbler, dry. For an easier solution, you could use a spray protectant, like as an acrylic spray such as Krylon, to give your slabs a nice glossy finish; just be careful not to scratch it when wrapping.Warning: Polishing your own stones can be addicting!Answer contributed by Dale "Cougar" Armstrong

### ⭐⭐⭐⭐⭐ Love this tumbler.
*by W***X on August 10, 2015*

I am very happy with this tumbler and have been using it for about a year. Easy, quiet, clean, good quality and good results. I also have a Thumbler tumbler which I am throwing away after one use because it is filthy (throws off piles of black rubber shreds), noisy and doesn't spin well . The Lortone is a winner. It is far superior to the Thumbler.

### ⭐⭐⭐⭐⭐ Great buy for beginner or hobbyist! Worth it!
*by E***Y on September 8, 2017*

I bought this for my son. He is 9 and loves rocks (he totally got that from me!). I'd wanted a tumbler as a kid myself so when he asked for one for his birthday, I didn't want to skimp. If you are wanting to get your child started on a hobby that can last them the rest of their life, lapidary art is a great one. But if you are really wanting a kid to enjoy it, buy a tumbler like this one that will last!!! Waiting the long times that it takes to tumble a set is hard enough for a kid, and the disappointment of having a cheapo "bargain" tumbler quit will be enough to help them loose interest in furthering their hobby. (I've known a few kids who got those and the tumbler quit a few weeks in. They never went back to try again.) So it is worth it to invest up front. Lortone is known for having some of the best hobby/light use tumblers. This model has two rubber barrels. Which is great for doing two stages at once, or having two different types of rocks going. Even a beginner can run this-- its literally plug and play ;) You will need to buy grit also-- none included with this piece. This is the one area I'd recommend grown up involvement. My son and 5 yr old daughter can load, sort and wash the rocks. But I add the dry powder. Some of the grits/polishes are ultra fine, and I cannot imagine that inhaling that stuff could be ok. It runs much quieter then I thought it would considering it's a spinning jug of rocks. But there is for sure some noise involved. This can't go in your kids bedroom! Or your own! Though in saying that I will say that it does provide a little bit of a white noise sound after a while that I have gotten used to. Maybe it would not be too bad as a background noise if you need to drown out traffic etc. But for most, the best location is an entry, garage or shed. It runs constantly, day and night, and the motor box stays warm-- though not hot. So I wouldn't leave it where you can't check on it once in a while or where there would be a danger of something falling on it.
