How to Make a Barbed Wire Gate Closer
Just because you want your barbed wire fence to close on its own does not mean that you have to buy a really expensive gate closer. You can easily create a gate closer that functions the same way as those you see in the hardware store.
Step 1 - Prepare the Plastic Bottle
Choose a screw cap plastic bottle that is quite heavy. It’s very important that you use a plastic bottle with a cap that fits nice and snugly. Test your plastic bottle by tightening the cap on. The cap should be able to fit properly without the treads being destroyed. This is important since you will be generating force when opening and closing your door. A heavy plastic bottle is also essential so that your gate closer stays intact after multiple opening and closing.
Step 2 - Make a Hole on the Cap
Make a hole in the center of your plastic bottle’s cap. It’s very important that the hole is just enough for your washing line or thin rope. If you make the hole too big, the rope will be able to easily escape out of it. If the hole is too small, you may not be able to thread the rope through it. Once you have threaded the rope into the hole, making a knot at the end.
Step 3 - Fill the Bottle with Water
Fill half of the bottle with water. You can add or take out water according to the outcome of your gate closer.
Step 4 - Thread the Pulley
Take the other end of your washing line or rope and thread it into the pulley. Make sure that you thread the line or rope properly. If aren’t able to secure the line to the pulley properly, you may only end up with a broken gate closer after just a few tries.
Step 5 - Setting the Gate Closer
Take the washing line pulley and attach it to the post adjacent to your gate. The washing line pulley should be placed at some height so as not to distract people who are going in and out of your gate. Take the bottle and place it in the topmost region of the inside of your gate. The pulley and the bottle must be within the same height. It’s imperative that you secure both structures properly or else they might be detached when one is opening the gate. Since you are dealing with force, such mishap can be physically dangerous.
Step 6 - Observe the Closing Speed
Once you have secured the gate closer to your gate, try opening your gate to observe the closing speed. If it is to slow, add more water into the bottle. The increased weight of the bottle is needed to come up with the necessary force required to close your gate. If the closing speed is too fast, drain a bit of water from the bottle.
Step 7 - Install a Latch
Look for a latch with an automatic latching and unlatching mechanism. Install the latch to your gate appropriately.
