I am going to show you how to make an A-Frame level that can easily be used to contour map your land. I will attach some photos and go through the basic construction of the A-Frame level and then I will give a video showing the level and how to use it to determine the contour of your land.
You will need:
First, cut the first 8 foot piece of wood in half, so you have 2 pieces that are 4 foot in length. brace them into a 90 degree angle. drill and screw them together.
Second, cut another piece about 2 foot in length. You will want to make your angles at a perfect 45 degree angle to the 4 foot pieces. and drill and screw it to the other pieces to make an “A” shape. I would want to find a perfectly level surface, and ensure that you attach it level.
Third, ziptie a cheap level to the A-frame level along the horizontal piece of wood. Now, go out and check the contour of your land!
Now, here is a video showing you basically how I built the level and how to use the level for contour:
