Sorry mate I didn't see this question. I haven't measured maybe 600 unscreened launder length wise. Screening down to 1/2 inch. Spent a couple hours today setting up the spray bars went from two inch delivery split into two 1 inch spray bars, fail, down to 2 inch to one 1 inch, fail, finally settling on 1 1/2 inch delivery into 3/4 spray bars.
The big rocks may belt the crapper out of it, so I've started mounting it with a spring tension which seemed to work really well, possibly might retro fit a guard. All in all I'm not too worried I have an amazing amount of this size stainless from the scrap days. Put in a flush t piece, and provision for a clean up/power jet hose. A custom Grizzly is now in order to keep the killer boulders out. Might even catch the first ounce by winter! !
Shovelled some dirt for safe keeping to round the day out, probably won't get out for a few weeks due to moving, hard times.
