Made me a little sand sifter for sorting out the lost foam sand after casting. Standard screen wire and a GT-10 turbine vibrator. A simple chute from flashing directs the first stage into the bucket. Then it got a weir to only allow 3/8" of sand to go to the second part. Works like a champ. Since my foundry floor is dirt I'm dumping the residue on the floor. It is rejecting some sand I would keep but sand is cheap and this is fast. That was a full bucket of sand processed with about a cup rejected. The screen has to be level enough to sift sand through and steep enough that the big pieces bounce on out. A little more level and the screen fills with pieces just barely too large to go through. My screen could be coarser but it is working.
