Drop Riffle Highbanker Progress

Worked on my four foot drop riffle highbanker some today. I just have to attach the legs, drill the water holes for the spray bars, seal it and waterproof (again), and add
the height adjuster for the grizzly. Some features:

Vortex matting under the grizzly as an 'inspection mat' you can check while running.

50 Drop riffles, including 25 double drops that have a smaller groove inside the main drop riffle for retaining fine gold.

2 stage system using 3/16 punch plate for 12 inches at the beginning of the sluice to allow the fine gold to settle out. I might add another stage of 12 inches of punch plate with 4 mesh if I am getting any fines in the riffles past the initial 13 inches.

Meant to say "your" equipment. Dang autocorrect.

Nice highbanker you made... How well does your drop down riffle system work? I like the drawer on the hopper... Good Job!
