If/when you purchase/make/diy blue bowl concentrator, the window screen will be too large. I tried it last summer, when I first attempted using the blue bowl.

Mesh size is measured as follows. 20 mesh screen is 1/20th of an inch opening between the holes. a 4mesh is 1/4 inches between the openings. 100 mesh is 1/100th of an inch between openings. hope this helps

Now that's a creative genius! I was trying last summer to bend an old street sign to form a sluice box. It was impossible without a brake. I finally wound up paying a fab shop to bend it for me. If I'd had this visual to go with, I'm sure I could have made a brake & done the entire project myself.

The green paint I presume to be chalkboard paint. it has a slightly gritty surface to it. I've got one like this set up. catch it II system it is here in the USA. I wasn't impressed with the system. Flow rates are too fast for the fine flour gold I have here in my area.
