Wastebasket Drywasher
I decided to use two rubberized plastic kitchen trash cans one for the hopper and one for the sluice, that ought to cover the electrostatic part. The riffle tray of course is made from aluminum and I made the stand from a 2x4 that I ripped into 3/4" x 1-1/2" x 48" struts.
Constructed the fan blade from a 6" duct damper (comes with a short threaded rod attached at one end) and then cut it into 8 pie shapes using tin snips stopping at the center washer, leaving the threaded rod centered at the end of one of the blades, put a heavy nut on it and it works perfect! Gives it that nice panning action
Bought the duct damper at Home depot for $3.95 not bad for how well it performs. Went through my scrap pile and found a great mount for it too!
I also am going to experiment with using a perforated (tiny steam vents) aluminum steam diffuser from a discarded grid plate from one of the steam presses at my wifes dry cleaners, instead of using cloth covered screen. Will have to see how that works out, but in my mind it should be an improvement over the traditional cloth covered screen diffuser. You would have to see it to appreciate the design, the steam vents are not holes that go straight through. Imagine a tiny dent with vent holes coming through two sides of the protruding part of the dent. then imagine about a hundred of those per square inch. If this works like I think it will, using, and replacing cloth will become a thing of the past.
Total cost including 3" quick connector and 10 feet of 3" RV discharge hose was right at $65.
Fan made from 6" duct damper
The arrows point to the two positions of angle for the hopper.
The connection to the front of the sluice was made using the bail from a discarded 5 gal bucket
