hey Kieth, I'm looking for some kind of 12 volt vibrator for this dry washer. Do you have any recommendations?

How about a 12 volt DC motor with a sliding setscrew counterweight so that you can adjust the amount of vibration... The counterweight will slide on a shaft, the further away the counterweight from the center of the motor shaft the more the vibration. The motor would need to be mounted solidly to the bottom of the hopper. The motor shaft would have the counterweight. A drywasher motor works on the same principal but uses air to rotate the motor and the counterweight creates the vibration.

Vibrating 12 volt motors are tough.

I have one of these: 3 Amp 24 Volt DC Powered Mobile Vibrator Motor with 50 lbs of Force - Power Concrete Mixers - Amazon.com

It's a good motor but expensive and there are a few things you'll have to do.
Such as add a variable speed switch that won't damage the motor.
That needs to be a pulse-width modulated switch.

Jay here is a link to what Doc mention above but in a 12 volt version of the vibrator. What I offered in my first post this Vibco does the same thing but for a whole lot more $$$. Yeah they are expensive but they are built to the spec's not to wear out. Whatever direction you go it all needs to be sealed bearings due to the dirt and elements of outdoors.

Pulse Width Modulation Switch Lots of switches, may find one already seal in a box.

The good ones are way too expensive for me. There's a place call Apache Reclamation in south Phoenix that might have a motor I can use. I'm gonna try there first and see what I can find.

so I found a 12 volt fan motor at the junk yard for $10. Hooked it up and tested some gravel. I got a few issues but nothing major. I have to tweek the angles and get the sluice level from side to side and I should do pretty good.

The first aluminum box came apart. This a steel version.

Jay did you make counterweight adjustable? Kinda curious how that blower motor is going to hold up due to the constant vibration. Is the motor shaft supported with ball or needle bearings or bushings?

 

[Justbent]

I'm not sure. It's a blower motor out of a car maybe. The place has a basket full of them so I'm testing this one.

I started small with the counterbalance and have added weight to where it is now. I should put a variable speed so it's not so loud when there is no dirt.

Seems like a lot of air in your water over the riffles, can that cause problems with recovery?

 

[Justbent]

I've have not run a serious recovery test but all the gold is in the first 2' of the sluice it looks like
