|Next, ideally you will have a dedicated worktop or table to use just for tumbling. The last thing you want is to have clutter around the machine which could become entangled with the drive belt causing it to jam. This will damage the motor (probably beyond repair) and stop the progress of your batch. Always keep tools and other bits and pieces away from the machine whilst it is working, you won’t be able to see it 99.9% of the time it’s running, so it must be in a safe place where it can run night and day without interference.
Because the barrel is full of rocks and water, and it is rotating, it naturally causes the tumbler to “walk” slowly along whatever it sits on. A slight slope in one direction, or a slippery smooth surface will aid this process and unless you take initial steps to prevent it, you will find it on the floor broken the next time you visit. To get around this, either fix it with screws to the work surface or table, or build a wall about an inch high (in wood) around the base, this will stop it moving as it works over the coming weeks.
