Lortone 33b Dual Barrel Lapidary Tumbler. I have only used this with aluminium only so the barrels will be suitable for metals as they won't have rock polishing grit residue. Barrels are modified with fin inserts, I found this helped get a better shine on my aluminium. See the photos for details.Included: 1kg of stainless steel shot. Used but in good condition. Plus 500g of mixed media shot, however, I'm not sure if this is stainless. Video of it working below. Instruction leaflet can be found here. Great for polishing metal and jewellery or tumbling rocks.
