This is what happens certain places, certain people. As I read the original question, just like Robo, I thought he was talking about a very ordinary vibratory tumbler, one just like I own and have used for more than thirty years. There are MANY THOUSANDS of these Thumbler Tumblers in use and they all use corncob and/or crushed walnut. So, I find it amusing to read above where this man says; "I haven't heard of anyone that uses a thumlers with corn or walnut."
But, that's what is going on, on the Hide. There is another world out there, and believe it or no, most of them have never heard of ss wet tumbling. BB (no offense mijp5)
