California Power Systems or CPS sells one for $16.95 which has a string attached to a bubble tube. The string runs from one side of the prop hub's hole, up thru a shank the size of the prop hub hole (and inserted into that hole), and to a washer to hold or hang it from something. The string balancer is hung high enough so the bubble tube on the bottom of the prop hub is observable. The bubble will have to be changed in each direction for vertical and horizontal balance. As of Oct. '03, Aircraft Spruce & Specialty or AS&S sells the same balancer for $21.50. For many years I have used a home made version out of a 1" oil plug (NAPA 4.50) with a hole drilled in the center of the bolt and a string epoxyed in. It is the most sensitive static balance possible as it gives a simultaneous vertical and horizontal balance. Hanging from the ceiling in a room with no drafts lets you paint & balance at the same time. George E.
