Pendulum clinometer

Some time ago ve mentioned this not too important but some what useful project. Some details were given of my intentions and some brats followed with dismissive questions. Some did not and showed a little interest.

Well, she is complete enough to show, while not mounted in the dash location till spring, you can get an idea of the final look. The 2 button head screws shown on the left will attach the gage to the right side of my chart plotter mount, which is right in front of my face.

The pendulum allows .002 of motion in either direction and on a tenth indicator this is bunch. .001 = plus or minus 30 degree's. I dont expect to use more then a couple tenths (.0000) each way.

The picture was placed in the detail section on this thread.

Here's the photo:

I can do that for you. (Took a while, thanks Marty and all)

Looks like a nice neat package.

What is the dial's diameter and purpose of the knobs?

The diameter of a group 2 indicator is 2 inch. That's the white part you see! Overall the gage is 3 1/4 by 3 1/4 inch.

I see no knobs. Re-read text and you will notice the knobs are actually the button head mounting screws.

Another photo was put in the "detail section" showing the extremely simple "guts" to my gage. The object looking like a horseshoe nail sticking out from under the aluminum bearing support is the "pendulum". It is attached to the pinion shaft in line with the needle and it's weight makes the needle hang straight. The needle hangs straight no matter how the gage is rotated, within it's range of motion, which as mentioned earlier is +/- 30 degrees.
Densealloy (used to make pendulum) is a tungsten carbide,1.5 times the weight of lead, giving gage a very positive action.

Thanks, Martin.

Sometimes the usefulness is in the creation. An interesting and well-done instrument.
