Measure & Mark Post Locations

alright now for the math and science portion of this video I have a 16-foot gate I'm putting it in an 18 to 21 foot roadway I want it centered in the roadway I have a 1 foot wide or a 12 inch auger now in order to make this work and have two to three inches of play on each post where I can adjust my gate up and down in this way in that way in order to do that I need to drill my holes 17 feet and 6 inches apart so the first thing I'll do is take my measuring tape and I'll lay it out here and I'll find the center of the road and what looks good and I'll mark the center with a little bit of paint then I'll measure out my 17 foot 6 inches drill my holes and set my post my post are 6 by 6 post the actual dimensions of the six by six is five and a half by five and a half so we'll set those post in we'll put three bags of concrete in one post hole the one that supports all the weight and we'll only put one bag of concrete in the one that just supports the gate latch cool did I lose you I hope so ok so here we are we've got our holes all marked out alright there's one hole right here is the center of the gate and right there is our next hole everything's all marked out now we're going to take this auger which is three feet and we're going to drop it all the way in so we've got 8-foot post and we want to drop them in to where there are about five feet of exposed post leftover now this doesn't have to be SuperDuper exact we're on a grade if you can't tell we're on a nice big hill right here so it doesn't have to be SuperDuper exact but we do have to think about which way we want our gate to swing let me get you back a little bit further and we'll talk about that the gate is going to have to open inward this way because there's a
