One more thing I might add. I don't favor the plumb bob being on the side on the dowel. If the dowel alignment is off a bit you will get an incorrect reading. I placed my plumb bob centered on the Tee. So from the ceiling to the tip on the plumb bob is one straight line. I have it where I can easily adjust it for height. For my type of airplanes that has not been a problem. Having a plane like your Super Sportster I will have to take a reading over the canopy. I will come up with something when the time comes.
