Materials Needed:
\n– Plywood or sheet metal (for the frame and riffle tray)
\n– 2×4 lumber or aluminum tubing (for the frame)
\n– Hardware cloth or expanded metal mesh (for classifying material)
\n– Canvas, burlap, or rubber matting (for riffle tray)
\n– Small electric fan or leaf blower (for air supply)
\n– PVC pipes or flexible tubing (for air delivery)
\n– Screws, bolts, hinges
\n– Legs or stand (adjustable height preferred)
\n– Vibrator motor (optional, for better material flow)<\/p>\n

Step-by-Step Construction Plans:<\/p>\n
# 1. Build the Frame
\n – Construct a rectangular box (~3′ long x 1.5′ wide x 1′ tall) using plywood or sheet metal.
\n – Reinforce with 2×4 lumber or aluminum tubing for stability.
\n – Angthe box slightly (~10\u201315\u00b0) for gravity separation.<\/p>\n
# 2. Create the Riffle Tray
\n – Cut a piece of hardware cloth (~\u00bc” mesh) to fit inside as a classifier.
\n – Below it, attach a riffle tray lined with canvas\/burlap to catch gold.
\n – Add small wooden or metal riffles (~\u00bd” high) spaced 2\u20133″ apart.<\/p>\n
# 3. Add Air Supply System
\n – Attach a small electric fan or leaf blower at one end.
\n – Use PVC pipes\/dryer vent tubing to direct airflow under the riffle tray.
\n – Ensure even air distribution with small holes along the pipe.<\/p>\n
# 4. Install Legs & Adjustability
\n – Attach adjustable legs to control angle and stability.
\n – A steeper angle increases material flow; flatter improves gold retention.<\/p>\n
# 5. Optional Vibration Mechanism
\n – Mount a small vibrator motor to help material move smoothly.
\n – Alternatively, manually shake the unit while processing dirt.<\/p>\n
# 6. Test & Refine
\n – Run test material (spiked with lead shot or flour gold) to check recovery.
\n – Adjust airflow, angle, and riffle spacing as needed.<\/p>\n
