My Dad got a kit when I was a kid to polish rocks and such. We had a ball with that thing. It had the tumbler, different media to mix in it. I found it in the tool shed 30 years later. Unsalvageable. Is there still inexpensive kits to get for that ? It is amazing what you get out of those with ordinary stones you toss in.
Prolly keep my kids outta my hair with one,,,,,,,,,,,for a minute. :sad:
Cool pieces you got posted there.

owl ...forgot to say the most important thing..if you make one this big ...you better have ALOT of rock to tumble ...rolers are like the ones you see on shipping set-ups...with a 25 ring sprocket tack welded to the roller to drive the one roller...studs on ends of rollers are tacked to the framework...and the top one is offset slightly to allow it a resting spot on the bottom tube so it cant roll off ...about 30 bucks into it after scrounging .... ...this one has been rolling continously (except for loading and un loading) for about two years ...steelco ...a supplier here in albany ore ...has pallets of the rollers if you cant locate any ...shipping wouldnt be to bad ...they sell for 2 dollars a piece let me know if you cant find any and i will get you some if you so desire ....pretty simple build ....enjoy buddy

In the early 80's I was a member of the Houston Gem and mineral Society and the club had lots of free stuff to use.Made cabs and had a lot of fun,Still wish I took one of those Mexican bus trips to some obscure place and they would dynamite the side of a hill and you went and carried out several hundred pounds each to bring back to the slab saws.

55 i know what you mean ...dont know what it is about mexico ..but dam they have some nice stuff there geodes filled with amethist BIG STUFF..(saw one with a man inside the geode 8 ft in diameter filled with giant amethist crystals and a hole just big enough for him to get inside ).the mexi lace agate is one of my favorites ..absolutely amazing matricies ....and colors ...my theory is its from the big metorite that hit down there and threw all the shock quartz and silicates all over the place...but who knows .... mother nature is one awesome momma ...gotta love her ..he he :)

My dad was a turqoise cutter in the 70's. Made a good living at it and was considered one of the best in the country. We later started tumbling turqoise in large quantity. He made 2 big tumblers that used tires as containers. We used the big offroad type as they were nice and deep and had a good fall rate. They rode on 2 lengths of 1" cold rolled steel, 1 hooked to a motor with a pulley and on the other end, were pulleys that tied the rollers together.
