# How to Build a Gold Sluice Rocker Box by Hand
## Introduction
Gold prospecting has been a popular activity for centuries, and one of the most effective tools for small-scale gold recovery is the rocker box (also known as a cradle). This device uses water flow and rocking motion to separate gold from gravel and sand. Unlike modern high-bankers or sluice boxes, rocker boxes are portable and can be built entirely by hand with basic materials.
In this guide, we will cover:
1. What a Rocker Box Is and How It Works
2. Materials Needed
3. Step-by-Step Construction Process
4. Tips for Efficient Gold Recovery
5. Maintenance and Adjustments
By the end, you’ll have all the knowledge needed to build your own hand-built gold sluice rocker box from scratch.

## 1. Understanding the Rocker Box
What Is a Rocker Box?
A rocker box is a manually operated gold recovery device that mimics natural river erosion processes. It consists of:
– A wooden or metal frame (“cradle”) mounted on curved rockers
– A perforated hopper (or “grizzly”) at the top to screen out large rocks
– A riffle tray below to capture fine gold particles
– A cloth or carpet layer underneath to trap fine gold dust
How Does It Work?
1. Material Loading: Dirt and gravel are shoveled into the hopper while water is poured over it.
2. Rocking Motion: The operator rocks the box back and forth, helping wash material down through the screen.
3. Separation: Lighter materials wash away while heavier gold settles behind riffles or in carpeting grooves.
This method was widely used during the California Gold Rush because it didn’t require fast-flowing water like traditional sluices did—making it ideal for small creeks or dry areas where miners had to carry water manually.

## 2. Materials Needed
Tools Required:
✔ Saw (hand saw or circular saw)
✔ Drill with bits (for holes & screws)
✔ Hammer & nails (or screws/nuts/bolts)
✔ Measuring tape & pencil/marker
✔ Sandpaper/file (for smoothing edges)
Building Materials:
▸ Wooden planks (½-inch plywood recommended for durability
