Today I decided to mark the trees where the main beam will go. I immediately ran into a problem: how to place a level mark on the two trees? The laser level and the regular level along with a string both depend on a bubble, which isn't very accurate across a twelve foot gap. Also, neither of those methods can set a level mark on both sides of a tree.
After a good amount of trying to make it work, I remembered how to make a "water level". This is so simple it borders on genius.
Materials:
- pick up a 25 foot length of clear tubing
- you'll also need a bucket
Steps:
- dunk the hose in a bucket and remove the air
- being careful not to let any water out of the hose, carry the hose up the ladder (you could carry the hose in the bucket)
- hammer a small nail through the hose at the height of the mark
- with your thumb over the other end of the hose, climb down the ladder and up to the other mark
- get close to the same height, and release your thumb from the hose
- watching the first side of the hose, adjust the height of the second side until the water intersects the nail
Congratulations, you've just made a highly accurate level!
