In the last entry we examined a few different types of common wire and concertina wire. In this entry we’ll take a look at ways of reinforcing existing fences to make them better obstacles. Your average fence that exists now is probably suited for a specific task. That task may be keeping livestock in, marking your property boundary, keeping feral animals out, etc. Often by just adding a few more features to an existing fence we can create a viable obstacle that will help us to achieve a desired effect. Remember from the last entry wire serves a lot of different purpose when it comes to defense. Regardless of the purpose fence obstacles all have one thing in common: they are a pain in the ass for humans (and vehicles) to deal with but they are not the one stop absolutely don’t let anything in solution. That solution doesn’t exist – but when it comes to the basic principles of obstacles wire is good – damn good. This isn’t a primer that’s going to tell you what a widowmaker is, how far to space your t-posts or drive them in, what type of barbwire to use, or how to use fencing pliers. There’s a gajillion sites on the net that gives that kind of basic info (there’s a good link at the bottom of this entry for it).
The most common type of fence you’ll see in rural areas is the steel T-post and barbwire fence. There’s so many schools of thought on how to put these up (tight wire, slack wire, post spacing/depth, etc.) that it’d be pretty hard to address them all here so I’m going to highlight their common properties. These fences normally consist of four or five stands of wire connect to standard t-posts at a fairly uniform interval. The pic below illustrates a pretty common type:
