Had the new wal-banker out New Years Eve for its maiden test run out on the creek. It got nick named Leuitenant Dan (as in from the movie Forest Gump) due to the fact that at the moment it has no legs.
Had to make a bunch more holes in the spray bars to get better coverage over the grizzly bars but after getting that sorted along with the additional flow it povided I was ready to give it a test run with some material.
The interesting part is without the expanded mesh, using only bread crate and the ulitmat I had perfect results. I captured two 54 litre tubs of tailings directly out the end of the bottom box and ran it through the MacKirk "Boss" and i'd be lucky to have caught 1/8th of a teaspoon of super-ultrafine blacksand (flour sized) and zero specs of gold, not even a single spec fly poo sized, absolutely zip!
After cleaning up the mats and processing the cons once I got home the tally was 1.98g of gold in about 2 hours or run time.
I'm now considering if I bother using expanded mesh at all given the results. Wal certainly stressed the importance of leaving a good 500mm for slick plate before the matting, at a guess I'd say I must have about 650 - 700mm (because of the missing mesh) and the box seemed to work fine as it was!
Just to finish up, a bloody big thanks to Wal and a huge thumbs up for his efforts in sharing the designs of his highbanker for us all! It works a treat and I'm a converted man!
