Ok....got one side down to 28 rpm on 15" wheels....really sounds like its doing much more than the higher speeds... I posted a video on YouTube Search Homemade boulder tumbler I guess I'm going to have to make a jack shaft so that I can adjust both sets of rollers...

One thing I learned while building different things....always make it so you can tweek it.....I left extra long shaft ends and can even run different speeds on the 2 different sets of rollers I opened the drums today.... First off....I'm running geodes....Michigan agate and also Pennsylvania quartz as my smalls The polish isn't working..at these speeds anyway....so I'm thinking I'm going to slow one set down..... I also tried a couple different setups..... I rough tumbled with 50 silica Then ran 70 aluminum oxide I have 2 drums from straight 70 aluminum oxide.... And I still can't figure out how to load a picture.....

And to think it was cranking at 90 rpm with a 12" drum.... Was cutting great....but the polish drum wasn't working correctly... 2 days on slower speed....going to open a couple ... Thanks for the great info...I was literally taking a shot in the dark

I wanted to thank everyone here about the rpm speeds. As you can see my user name....you will start to understand..... I bought a small 3 lb tumbler at the flea market 10 bucks.... I've plugged it in once to find rpm speed....it was 50 rpm...a harbor freight model.... But just being myself...I built my own tumbler....it is....big....I made my drums out of 4 gallon buckets....with 3/8 rubber matting liner....made end wheels .....I get about 40 pounds of rocks per drum....I am currently running 5 drums...with room to grow.... Through my 3 step refinement....speeds changed...was spinning 90 rpm....kinda scary....60 lbs drums..... Dropped the rpm down to 50 rpm....but now have a different vibration from the weight of the rocks....(fist size and smaller) I have to admit....the faster rpm really did a good and fast rough tumble.... Once I figure out the site I will post pics and videos... Mike
