I bought a Harbor Freight Vibratory Tumbler. It fell way short of expectations so I applied a little simple physics and I now have a great Tumbler. In production it would have cost no more to implement than the original flawed design.
I made a video explaining the very simple modification that I made which transformed the machine. I regard the problem as a design flaw and in production it would have cost no more to have done it correctly. See what you think. I suggest watching it on Youtube.
