This is a small vibrating table with a lip which holds a thin layer of water and grit. The rough shaped piece of slab was attached to a dop stick with some sealing wax so you can present it to the grinding wheel without losing your fingertips! There is also a flat lap machine to polish one face of a large stone. These were used to make cabachons for use in jewellery findings. Other gear I inherited was a diamond saw to cut slabs and a bench grinder with different grades of wheel including a buffing wheel for polishing. Now I’m retired I intend to drag the old tumbler out of the shed and get it going again again with some of my choice finds. Sixty years later I still go to that same beach at low tide and often find several agates if big seas have moved the sand cover and the stone beds are exposed. She used tin oxide as the final polish after the last (carborundum?) grit stage. The finished results were beautiful, especially the hardest stones like the agates. I don’t know how essential this was, I just wanted to put it out there. Occasionally she “burped” the containers by stopping the tumbler, removing the container, briefly unscrewing the lid to release any pressure buildup, retightening the lid and starting the tumbler up again. This also helped in reducing the amount of material lost. The coarsest grit stage could be reduced or omitted. Also, as beach stones can be quite smooth from the natural tumbling effect that has occurred from wave action, selecting the smoothest ones for a particular batch shortened the time required to tumble them. It is inexpensive, extremely hard, and crushes into sharp, angular. She found that a having variety of sizes of stones in each batch worked better.

And in the future when you want to upgrade to a larger tumbler, they make several other models which allow you to grow into the hobby. They’re also much higher quality than other brands and will last a very long time. These brands have been around forever and build everything in the USA – they also have great warranties. If you know the child will love the hobby (as most do) OR if budget is not a concern, go with the Lortone or Thumler’s. It’s priced pretty competitively and is a big step up from the ‘toy tumblers.’ If you’re not sure whether the child will like the hobby and don’t want to break the bank, then go with the Chicago Electric model. They are both made overseas and use cheaper parts than other models. Just be aware that these tend to break down more often than the professional-grade tumblers. If you’re just looking for more of a toy as a gift, then go with either the NSI or Smithsonian model. If you’re still having trouble deciding which you should buy, consider the following:
