Prop Balance.

       Remove this ad - become a site supporter!
Ok so I have a balancer. I know how it works,but what is the best way to balance a prop especially an electric. I have a large APC type prop 18x10E that when placed on my balancer drops readily to one side. The heavy side. Now because of its shape I was thinking along the lines of sand both ends(for adhesion) and dip it in paint both ends for colour match then the light end until it is the same balance both sides. This should serve three uses. One make the spinning prop more visible,Two balance the prop without changing its shape and Three hopefully make it better in appearance
To a tree, balsa wood and MonoKote taste just like chicken!

Re: Prop Balance.

Eventually the paint will wear off restoring the prop to it's original unbalanced state. Sand the forward facing face of the prop to balance it. Balance the hub as well, A properly balanced prop will come to rest at any position on the balancer. If it always stops in the horizontal position you will probably find that the same side of the hub is always on the down side. Remove material from that side or add material to the other.

Re: Prop Balance.

I have balanced props from 6" to 8' and it is easy.

All you need is a flat level surface and a round rod half the size of the center hole.
1. Make sure the center of the hub is flat and smooth.
2. Place the prop on the flat level surface back side down.
3. Slide the round rod under the center hole at 90 deg. to the prop.
4. look straight down the hole and turn the rod slowly each way until the prop rocks back and forth.
5. Notice the size of the space left between the side of the hole and the round rod as it teeter back and forth.
6. The smallest space will be on the heavy blade side.
7. Paint the back side of the light blade with your favorite Trem clad color.
8. Recheck balance after paint has dried.
