What is typically used to correct horizontal unbalance of a wood propeller?

Explanation:
When a wood propeller shows horizontal unbalance, you correct it by adding a small counterweight to bring the rotating assembly into balance. For wooden blades, solder is used to attach that weight because it lets you apply a precise, small amount of mass without disturbing the blade’s shape or weakening the wood with heat. Welding would risk scorching or damaging the wood, grinding would remove material and alter the blade geometry, and epoxy is not as precise or easily adjustable for small balance tweaks. Soldering a metal weight onto the blade provides control and preserves the blade’s integrity while achieving the needed balance.
