Re: Early Cutlass bearing wear. Is this a problem?
I use a piece of shaft the same diameter as my main shaft with the taper cut on it, and two drill holes ,one on either end. I put the prop on this taper. A jig which holds the prop, on this shaft thru two sharpeened bolts in these pin holes lets me see which is the heavier blade. If I grind the heavier one down, to the point where, when I spin the prop, it stops at a different point every time, the prop is balanced. Leaving this shaft a bit long, lets you hold a patten on the blade and line it up with the shaft for pitching it.
