this set will be the running of gem gravels. will do a cleanup in another segment as there is 13 pics in all.
pic1. up and running with safety screen in place.


pic2. looking down sluice. note past the last slick plate and in front of bottom 1" riffles, gravel buildup.

pic3. feeding of gem gravels

pic4. note settling of heavys. the 1' riffles at the bottom create a low pressur zone. like in a river system.

pic5. note the red line across and below the riffles. this is garnet fines being held in place

pic6. looking up into the top end of sluice

the bottom riffles are 1" they create a low pressure zone in front of them. the middle and upper 1/2" riffles. the safety screen at the discharge, check for any gem rough that may spill out, due to overfeeding or when it is time for a cleanup.
