My Home made tools

A few pics of my Highbanker , River sluice, the river sluice is actually the bed of the highbanker with added flare and classifying screen. The final design of the highbanker was achieved after about 6 versions, much experimentation but finally happy.

looks cool mate well done. James

Looks good with that punch plate and all

I can confirm how well Barry's high banker works. The pics don't show that the top section is straight expanded duralumin mesh with no carpet or miss underneath, only about a foot or less of it. The bottom section is bread crate over moss. The top section holds almost exclusively heavies and the gold. Less than 5 % or so of the gold is recovered from the moss.

Yes indeed you can tell it is good just by looking at the unit. I would say it can handle two men working it without any bother at all.

The duralumin mesh works very well, exchanging very efficiently. I'm after a bit to try in my high banker, which currently has riffles over expanded over carpet.

Back in the late 70's i helped a couple of American school teachers who came out here dredging, their dredge was fitted out in the same way and believe me it was a BIG dredge almost 3 feed wide and 20 feet long. They knew their stuff and showed me every thing i need to know about dredging. Can you pitcher a 4 liter paint tin full of gold man what a sight. And over the course of a year or so i am not talking one tin either. The weight of the tins i will never forget that for as long as i live. cheers

Hey Chris I can accommodate you with the same mesh, it is the same as the one I gave Barry.

Pete, that would be just great! I'd only need a foot of the stuff if you have it to spare.

Pardon my ignorance but what is duralium mesh?

Duralium is a type of aluminium typically originally used in the aircraft industry, it is harder than commercial grades of aluminium and usually has a designation like 24srtx, xx75, x7 and heaps of others each having different properties. The changes from standard commercial grades are able to be acheived by altering the alloy for each grade and then the material is heat treated to obtain the properties that are required for that particular grade.

Looks like a great unit.
