Electric fencing can be expensive but there are alternatives to the high-priced electric fencing components. One such alternative is a DIY insulator for stringing your electric wire on.
So first find a empty plastic soda or water bottle with a fairly deep lid. Don't remove the lid from the bottle until you're done making your holes and a slit. I use the water bottle to hold the lid so I can safely drill and cut the lid without having to have my hands in close proximity to cutting blades. First I drill an 8th inch hole all the way through the lid so that it comes out the other side.
I then take a saw such as a Dremel saw blade and I cut a slit from one whole to the other.
Then I drill a 16th inch hole in the top of the lid.
This is what I will use to screw the insulator to a fence post. Preferably a screw that will set recessed away from the wire. Optionally, once I have attached the insulator to the fence post I may use a small dab of silicone or hot glue to insulate the wire from screw if I think the wire is too close to screw.
(A small piece of plastic placed in the lid, over the screw will also work.)
Once I have attached the DIY plastic insulator I will give it a good coating of spray paint to keep the plastic from decomposing. Almost all plastics are treated with cornstarch so they will decompose. Personally I think it's just so that they can force people to buy more product but nonetheless a coating of spray paint will prevent plastics from decomposing.
At this point you're ready to string your electric fencing, just slide the wire down through the slot into the holes on either side as shown in the photograph above.
Attach your electrical fencing to the charger and you're ready to go.
