Here are few photos of a classifier I made for a friend. I have another one that I made before this but the parts I used for his are readily available at Home Depot. This really increased my production the last few times I went to SW Arizona. I used a wire drawer, a plastic tub. some 1/4" good quality plywood, some light angle-aluminum, and 1/4" hardware cloth. The drawer fits perfectly into the tub but is still easy to remove so you can dump the larger material. I used mine for about 10 days of hard use before I had to replace the hardware cloth. The last time I was out, I ended up running 40, 5 gal. buckets of 1/4" material. Just thought y'all might like to see this. Any questions or comments are welcome. Chris
