Buy a pro type shaker - not a shell cleaner or polisher - the gun
ones are to light weight and will come apart.

The pro ones have a thick plastic bowl and can handle a lot of material.

I have both - one for reloading - one for small metal stuff.

I bought mine - and the ceramic shapes from MSCdirect.com

I am beginning to find out all the little glitches. Even some of the so
called "industrial" units do not have bowls that will take ceramics or
steel.

I am still not entirely clear how the vibrations are generated in these
units. I managed to find an exploded drawing of one and it seems that it is
the motor body that is attached to the bowl rather than some sort of
cam-shaft arrangement shaking the bowl.

I am trying to visualize how to get a big plastic bowl to shake at 1700 Hz
with a motor cannibalized from a drill press :-)


I have (5) 15 lb brass "vibrators for polishing brass cases, and a 50
lbs one that I use for brass, small parts etc etc

they all typically have a motor with a weight on the shaft that is
lopsided. The 50 lb one has a belt from a motor that spins a shaft
bolted to the bottom of the bowl, that has a big brass "half moon" on
the end of it. All of them have springs that carry the bowls.

The small units get walnut hulls with a touch of Brasso, the big one
uses either walnut hulls as above, or various ceramic shapes of various
sizes, depending on what Im cleaning up/deburring

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
