Designing Your Water Wheel

The design phase is critical to ensure your water wheel functions effectively. Consider the following:

Step-by-Step Construction Guide

Here’s a detailed step-by-step guide to constructing your water wheel:

  1. Cut the Wheel: Use wood to cut out the circular shape of the wheel. Ensure it's balanced.
  2. Attach the Blades: Securely attach blades to the wheel. Consider their angle for optimal water flow.
  3. Create the Frame: Build a sturdy frame using wood. It should hold the wheel securely and allow for free rotation.
  4. Install the Axle: Insert the PVC pipe through the center of the wheel, ensuring it rotates freely.
  5. Water Channel Setup: Design a channel that directs water towards the wheel effectively.

Installation and Testing

Once constructed, it’s time to install your water wheel:
