I don't ship overseas and work hard to vet my buyers to avoid punting the problem over the fence. But there are, unfortunately, too many willing to do what you say.
Shark is definitely getting empty. I've been busy reducing inventory ahead of the move. Might have a couple pick ups that need to be made, but working hard to empty out.
This one didn't need a respirator or dust mask. I've started keeping N95's ready for when I suspect vermin. Some of my medically trained audience have told me the dust from vermin remains can carry potentially nasty stuff.
I'll have to adjust once I get relocated and start getting real numbers. The basic principles are the same but the variables will change. I'll be sure to share as I get settled in.
No idea who that was so had to look it up. Not really, mine is probably older than half the staff he has there. Going to be 50 years old at least, it’s kinda like a slice box that moves around to keep the material from packing up. There is still some manual cleaning afterwards but it definitely helps concentrate the material. When I was a kid we would go down to the river with a small sluce box and run a whole bunch of sand through it. We never made any real money as gold isn’t that concentrated here but we did find some. Maybe 400$ over our whole time. We would use the table to concentrate the sluce material further and then hand pan the rest with tweezers.
