DIY Rock Tumbler

This has long been one of my bucket-list projects and my grandson's interest in rocks has spurred me on to get it done. I had saved that .75 inch shaft for years for just this project. Now to get it painted and finalized. It will hold three of these drums made from 4 inch PVC about 5 inches log. The drums would hold 1.5 to 2 pounds of rock easily. Similar drum OD to commercially available drums if I ever need one. These are so much cheaper. Scrap PVC and a plug and cap, total about 5 dollars. 1/2 inch PVC pipe was split lengthwise and welded inside for agitators, to keep rocks tumbling instead of sliding.
