So you are interested in making tumble-polished gemstones? That’s great! I would like to show you how easy it is to turn the rocks shown on the left side of the photo at right into the tumbled gemstones shown on the right side of the photo. We will go step-by-step through the tumbling process using plenty of photos -- so that you will understand exactly how it is done.

Everything is cemented into place. Extra cements it poured in to the wall to "lumpy it up" and make it tacky for the hard plaastic liner
I'm guessing that the ABS variety of pipe I chose (for price cheap) would scratch and file away by the hard grit pretty quickly, so a hard liner is in order. I priced out liquid truck bed liner, yikes $$$$$$
