Introduction to Fiber Rods 0:09
- The video begins with an explanation of four-foot fiber rods we use for creating electric fences. Glenn mentions the different colors available and discusses the sun guard coating that prevents fiberglass exfoliation, reducing wear and the need for gloves.
Setting Up the Fence 0:50
- Glenn covers the ideal height for grazing, with details on inserting the rods into the ground and optimal wire spacing. Adjustments for uneven terrain are also mentioned.
Fence Post Angling and Spacing 2:12
- Glenn describes starting a fence from scratch using fiberglass posts, detailing a method called the “dead man” post setup. Instructions on angling and spacing posts for different types of ground are provided.
Understanding Hot Wire Twines 4:00
- Various types of hot wire twines are discussed, including the importance of nine-strand twines for better conductivity and strength. The importance of friction between the stainless steel wire and fiberglass posts is explained.
Knots and Tying Techniques 6:07
- How to tie knots effectively. The video demonstrates two key knots: the self-tightening “dead man connection” knot and a basic tie for regular post-to-wire connectivity.
The Basic Essential Knot (don’t miss this) 8:00
- Glenn shows the basic polywire knot that we use in general fence setup. This is the MOST important knot he will cover, so be sure to watch this part.
Importance of Tension 11:02
- Glenn discusses how to maintain correct tension in the fence to ensure effectiveness. He provides tips on how spring tension from the fiberglass posts helps create a tight fence, which improves the likelihood of livestock respecting the boundary.
Fence Maintenance and Removal 12:02
- The video concludes with advice on maintaining a hot wire fence, including how to adjust or remove the fence easily. Glenn shares his personal opinions on why he doesn’t like clips and prefers to use knots.
