Its not that you cant make your own..but it usually ends up way cheaper to buy one. Unless time is no issue.
Shaking a tub or bowl is easy..the trick is the correct shape. The parts have to move around the tub or they will just sit in one place beating against each other. The only design that is fool prove to make is when you rotate a barrel laying on its side. It doesn't put much energy into the part so it only good for final finishing..not taking a burr off.
After many years of this I can tell you another trick I have learned. The best and fastest way to deburr is while its still in the machine. A little more time in the machine with some special tool paths will save a ton of time beating them to death in the tumbler. You still end up finishing them but its a lot easier and quicker.

i will purchase a db300 next time i feel in need of a vibratory finisher.
