Re: hand tools - How do I read a level?

Question

I have a two foot level with two vials in the center and two on each end. I don't know what the bubbles are supposed to do and I cannot find instructions anywhere for reading this tool . Are they supposed to balance simultaneously? I am attempting to install vinyl windows.

Answer 1

You only read one vial, depending on whether you are trying to level horizonally or vertically. Some tools also have a vial for 45-degree leveling.

The air bubble inside the vial will be perfectly centered between two lines when the tool is level for the given orientation.

Hold the tool horizontally level -- one of the vials in the center is usually oriented parallel to the tool and will tell you if it is perfectly level.

If you hold the tool vertically level, one (maybe both) of the vials at the ends will tell you if you are tilted slightly to the left or right.

Place the tool on the sill of the new window, or hold it vertically against a jamb and read the proper vial.

Answer 2

Many levels have a straight (in line with the level) glass tube with liquid in it. There should be two lines on the glass. When you have it level, the bubble of liquid is between the lines. You may also have a glass vial that is on an angle (45 degrees) for establishing that angle. The vials on the ends should go across the width of the level and are used to "plumb" the edges of surfaces that are vertical.

Answer 3

The bubbles should be in the center of the vial (between the lines). The long side of the level is for horizontal position, the end is for vertical position. So, for the horizontal position, you put the level long ways, for the vertical position, you put the level up and down.

Answer 4

the bubble lets you know if it's level or not. When it's in the center, then it's level

Answer 5

You cannot be serious. If you are they need to be new bubbles, You can purchase new bubbles, Just ask at any hardware store.
