[QUOTE="Nightjar, post: 515816, member: 1414"] Dry blowers, not dry washers, WA's old timers would be rolling in their graves hearing this. Forget about static electricity, yes fly wire under the cloth. Riffle height is not really important, the higher the riffle the more fines retained, more fines means more washing/sluicing (using water :playful: )at end of day. GM, when you get your machine trialing a sure way to check performance is to wash fines from upside of each riffle. Gold should not get past the first two riffles. Top screen mesh approx 10mm. Always check top screen, move machine away from the spill at end of day and run your detector over piles to check for the any "big ones" Back in the early 90's we found a lot of gold retreating the "old fellas" dry blowing heaps, surprising how much they walked away from. One reason I suppose, there was an abundance of gold and they didn't waste their time getting the crumbs and mustard gold. [/QUOTE]
