Here is the pump/gas engine I will be running.
This is gonna be the smallest 2.5in dredge you have ever seen. Just got to make sure it is NOT top heavy. More tomorrow, crash box will be done.

This was made from old aluminum meat trays, that I cut the lip off of and started bending in a vise. Nothing fancy, all by hand at my dads shop. A cheap pack of aluminum pop rivets and the crash box is done.

The part the rubber flap is connected to, flips up toward the front of the sluice to use a rod to unjam rocks from the jet and clean and check the first mat and punch plate. More to come.

Those little proline high banker dredge combo units in stock configuration tend to not have very good recovery, the jet come right up into the box under the hopper, there is no baffle or flare to slow down the flow before the I have seen pickers get blown through one. I’m personally a fan of flare headers but they do increase the length of the machine. Having the motor mounted like that should really vibrate the sluice.

I'd pull the stock riffles and go with expanded metal.
I was thinking of that, until then I took some Krylon Appliance Epoxy and sprayed the rusty riffles. After a wire wheel and 80 grit then 120 grit. It looks nice.

I was thinking about putting a baffle of some kind in the crash box.
