[QUOTE="Nightjar, post: 515572, member: 1414"] GM, Steel mesh is a good idea when placed under cloth mesh, it supports the fines load spilling onto the riffle box. The cloth is used because with every puff the cloth flexes upside of riffles agitating the fines, the light material spills over the ridge and the same process is repeated at every riffle. When angle and bellow stroke is set correctly gold usually doesn't get past the top two riffles. The angle is around 21. Get your self a small two way spirit level (most caravan outlets have them) glue it to horizontal frame of dry blower, set your riffle box angle (21) at home on level floor. Then when you get to your dryblowing destination the setup is a simple matter of leveling the machine. BTW any tight mesh cloth is suitable, fitted flour bag cloth to my mini dryblower. (picked up at Op Shop for a couple of $$'s.) Good luck. [/QUOTE]
