Default Tip: Wooden Prop Static Balancing Stands

I have another possible method to static balance a prop which I think may be more sensitive.

It should work for 3 blade props too. The idea is to suspend the prop by a mono-filament fishing line. The fishing line offerer virtually no resistance to bending, and thus a near perfect balance point. Have the prop suspended in the horizontal plane at its centerline. That supporting point can be a circular disk, centered on the prop hole, to which the fishing line is attached at its center. This method will reveal any imbalance for a 2 or 3 blade prop. For a 3 blade, it will reveal the direction of the imbalance even when not along a particular blade. Also this will not have starting friction or bearing friction as might the roller arrangements.
