For me building a fence starts with getting posts plumb and in a laser straight line.
String line fence post.
Well this is where you have to sort of take a guess or at least i did.
To ensure the posts are even in height run a tight string line between corner posts and end posts.
Mark the positions of the line posts and dig a hole for each one directly under the string.
The outside edge of the stake should just touch the line.
The following formula will help you compute the number of fence posts you need.
Considering this your corner posts should be longer and if possible larger than your line posts.
Use a string line level or bench level to make sure the line is level then check to see that.
Measure the positions of the posts with a tape measure and drive a stake at each point.
The lower string is to the ground without touching the ground the better.
Pulling a string it s really called mason s line tight between two points is the best way to build a fence straight and true.
This can easily throw your fence line out of alignment.
Stretch mason string between the centers of all the batter boards to delineate the perimeter of the fence.
At this point you pull the string to where you are placing the opposite end post.
How do you know you are parallel with the property line is the fence actually on the property line.
Drop a post into each hole and line its face up with the string while you plumb it.
The longer the run the tighter the string needs to be to stay straight.
Hammer your stakes in clear of your post holes so that the stakes are not disturbed during digging.
Using your string line you will run the string on the outside of the soon to be installed fence.
