# How to Build a Gold Rocker Box: A Step-by-Step Guide
A gold rocker box, also known as a cradle, is a simple yet effective tool for separating gold from gravel and sand. Used during the Gold Rush era, this device remains popular among prospectors due to its portability and efficiency. Below is a detailed guide on constructing your own gold rocker box.
## Materials Needed
To build a functional rocker box, gather the following materials:
– Wood: Use durable lumber such as pine or cedar (approximately 1×6 or 1×8 boards).
– Screws/Nails: Rust-resistant fasteners for assembly.
– Mesh Screen: A metal or plastic screen (¼-inch mesh works well).
– Carpet or Miner’s Moss: For trapping fine gold particles.
– Legs/Rocker Arms: Wooden supports to allow rocking motion.
– Silicone Sealant: To prevent leaks at joints.
## Step 1: Design the Frame
Cut wooden boards to form a rectangular box approximately 36 inches long, 12 inches wide, and 6 inches deep. The exact dimensions can vary based on preference, but this size balances portability and efficiency. Assemble the frame using screws or nails, ensuring all corners are square and sturdy.
## Step 2: Install the Screen & Riffles
At one end of the box (the upper section), attach the mesh screen securely using screws or staples. This screen filters out larger rocks while allowing finer material to pass through. Below the screen, install riffles—small wooden slats spaced about an inch apart—to catch gold particles as material flows downward.
## Step 3: Add Trapping Material
Line the bottom of the lower section with miner’s moss or carpeting to capture fine gold dust. Secure it tightly so water flow doesn’t displace it during operation.
## Step 4: Attach Rocker Arms & Legs
Construct two curved legs at one end of the box to create a rocking motion when manually operated. Alternatively, use pivoting arms underneath for smoother movement. Ensure stability so the box doesn’t tip over during use.
## Step 5: Seal & Test for Leaks
Apply silicone sealant along seams inside the box to prevent water leakage. Once dry, test with water before adding gravel—adjustments may be needed if leaks persist.
