PVC project: Larger drum for HF dual drum rock tumbler..clean reload brass!

[Mar 19, 2016] This video gives details for making a 4" PVC tumbler drum to fit the Harbor Freight dual drum rock tumbler for wet processing of reloading brass. The single larger drum makes it easier to process larger cases and may increase capacity. Special thanks to gds from 300blktalk.com for the Idea!
