You're a fine hasher Green, but 200lpi?, don't you mean 200 micron to initially sift your starting material?
for those who are new to dry sifting and meshes here's a mesh chart
http://www.tempo-foam.com/engineerin...illimeters.htm
"micron" is a metric measurement of the exact distance between each mesh thread,
"LPI" or lines per inch is a count of the number of threads or lines within an inch and often is written as for example "125 Mesh"
here's the Tumble Now...which has a 125 micron/140 micron S/S mesh cylinder and 200 lpi/70 micron flat screen mesh that sits on the pull out drawer.
