Lecture on Bending EMT Conduit

Introduction

• Presenter: Dave
• Topic: How to bend EMT conduit using a simple hand tool.
• Purpose: To showcase bending EMT conduit for DIY projects.

EMT Conduit

• Definition: EMT stands for Electrical Metallic Tubing.
• Where to Buy: Available at local hardware stores.
• Uses: Great material for DIY projects due to ease of bending.

Tools Needed

• EMT Conduit Bender
  • Cost: Less than $35.
  • Users: Commonly used by electricians.
  • Features:
    • Cast die head.
    • Long handle for leverage.
    • Foot rest for applying force.

How to Use the EMT Conduit Bender

• Basic Usage

  • Place conduit into the bender.
  • Apply leverage through the handle.
  • Use foot rest to push down and bend the conduit.

• Markings on the Bender

  • Arrow: Aligns where the bend starts on the conduit (e.g., 12 inches from the end).
  • Angle Marks: Aligns conduit for specific angles (e.g., 45-degree, 90-degree bends).
  • Specifications: For 3/4 inch EMT and has a 6-inch radius.

Practical Example

• Example Conduit: Bent with a 6-inch radius.

• Use of Star Marking

  • Allows for U-bends with parallel legs.
  • Important to keep bender and first bend in the same plane to avoid dog leg (crooked bends).

• Correction of Over-Bends

  • Insert over-bent conduit into the handle.
  • Use handle leverage to correct the bend.
  • Achieve precise measurements (e.g., 24-inch distance for table legs).
