Hello....I am making a vibrating table to polish marble.
Would appreciate input on the mechanism to make it vibrate.
So far.....steel pan....4' x 2' mounted on 4 heavy duty rubber isolation mounts.
Idea 1....4 foot long HORIZOTAL shaft in 4 pillow blocks...and 2 cam lobes running along the side of the pan....pushing it sideways.
Idea 2 VERTICAL shaft underneath with a cam lobe on the end....spinning around and hitting a metal bar, welded to the bottom of the pan...pushing it sideways
Idea 3 Vertical shaft underneath with a cam lob spinning around inside a ring....welded to the bottom of the pan....pushing out in 360 degrees....
Idea 4 should I do something with an eccentric? if so what?
Would appreciate any input...
Thanks, Leland
