Svimmer Posted October 11, 2017 Share Posted October 11, 2017 Any one got any experience with this rock tumbler ? http://i.ebayimg.com/images/i/262993571800-0-1/s-l1000.jpg Link to comment Share on other sites More sharing options...
greenlight Posted October 11, 2017 Share Posted October 11, 2017 I have a much similar model, it takes a lot longer than a large mill but does the job.I run it for about 8 hours with 850 grams of lead and 150 grams of powder before it starts clumping. An additional half and hour and its done. Link to comment Share on other sites More sharing options...

Mortartube Posted October 11, 2017 Share Posted October 11, 2017 I make 100g at a time and I use a Beach 3lb tumbler (A British make). I use one of these as a mill jar. https://www.therange.co.uk/cooking-and-household/cooking/kitchen-accessories/food-storage/tupperware/whitefurze-beaker-and-lid?gclid=EAIaIQobChMIlvG9vt_o1gIViCnTCh2VIg3AEAYYASABEgI47PD_BwE Link to comment Share on other sites More sharing options...
Arthur Posted October 11, 2017 Share Posted October 11, 2017 (edited) Rock tumblers work well but take smaller loads and usually take a long time. They are significantly improved with a rubber drum and ceramic media. They really will not turn a drum half full of lead balls, so you use fewer balls and mill more slowly. BUT the price is right! My rock tumbler has a 40w motor, an equivalent mill would have a 200w motor. Likely everyone started with a rock tumbler!
