Nice build!
Did you incorporate a bump stop at the top of the bellows stroke? I think that is an important feature for puffer washers.

 

[xracer550]

No I did not , But it wiggles around quite well for sampling .

A bump stop would be a nice addition and probly wouldn't be much to incorporate into your design ! NICE JOB !

Can someone show me where it Goes & how it works ?

Usually the bellows frame abrubtly contacts/bumps the frame around the riffles, causing the material on the cloth to bounce, before the bellows starts the downward motion. That helps the gravels, etc. to sort out and be discharged in the tails.
Still like your build.

I have an old beck's Dry washer that has an eccentric cam shaft under the sluice to bump the tray. Along with the bellows works great gasoline driven motor actually an old washing machine motor. Too much dust for me and the desert is a long drive.
