I have always wanted to build my own tumbler, mainly for the fact that I don’t want to buy one. I was lucky enough to inherit one from Frankie, which caused to me stall out on designing a cheap one. Until now because I have come to want two of them for tumbling rocks and polishing up metal.
So this is tumbler V 1.0 which has a few faults but I have plans to update this and refine it. It is made of laser cut acrylic and some basic hardware that I had laying around. This is a great first run though and I now know what I need to add to it to make it run just a bit smoother.
Currently the supplies are:
1/8th in. acrylic
5/16 threaded rod
silicone rubber o-ring
12v DC motor
rubber drum(from my other tumbler)
and it is being powered by a variable power supply. I will soon give it a dedicated power supply but this is good for testing.
