Auto-media sifter type vibratory tumbler.

[WestKentucky]

I saw a post earlier about using a built in media dump slot to sift the brass and media. Just curious...does it work, and how well does it do?

It looks so simple I could take my harbor freight rig and put a drain spout on it, but before I break out the drill and wallet I want to know if it is...
Messy
Effective
Problematic
Dusty
Worth risking my tumbler on trying to modify it.
