Newbie here - are photos welcome that are peripheral to the original topic? I respect limiting replies to serious discussion only, if that's what the site prefers to stay focused on.
I would love to see.

Practical application of an eductor: Hobby mining on our gold mining claim in the Northern Sierras 2008.

For 30 years we used larger gear I designed and cobbled together out of available materials. (Application of my interest in practical engineering). I finally decided I was too old to backpack a 5hp B&S engine (rototiller engine), my kids were grown and less interested in being my pack mules, and I could afford to buy the factory-built components shown here.

Stock photo, illustrating the 'suction nozzle' I am operating. The alternative, a 'power jet' installed at the intake to the sluice box, is shown in the Keene links I included in post #3 above. That alternative has greater lifting power, but is not suitable for shallow water since it loses prime if the intake is allowed to suck air for a moment.
