I've read the thread "The physics of a dropweight tensioner" (good description there) and am also aware that stringway manufactures a automatic dropweight. I am not sure how the stringway machines work, but reading the above thread got me thinking about a way to make the bar horizontal after his has dropped. The "The physics of a dropweight tensioner" makes it clear that as long as the dropweight is parallel to the ground (or close to it) the tension will be exact (or very close). Then I started thinking, what if i put my klippermate (or any other dropweight) on top of a plane that could be rotated forward and back. If the bar doesn't drop far enough, simply tilt the plane so the side with the bar is down (machine is secured to plane) until the bar is parallel. The same could be done in reverse and the plane could be made to rotate, say 45 degrees in each direction. With 45 degrees as a room for error the bar shouldn't ever have to be dropped twice. It may be a bit of a hassle to put in the clamps with the machine at a angle, but it shouldn't be do bad. Thoughts?
