Ever wondered what it looks like inside your barrel? Having the perfect combination of rock size, similar hardness, amount of water, rock level, rotation speed etc makes a huge difference in getting the best results. Alot of customers have asked a variety of questions regarding the tumbling process so I will soon be uploading a series of short videos. These videos will go into the fine details about everything you need to know to get great results so you don't waste time and $$ making mistakes, which we all know is very frustrating.
