This is the Prop Balancer I built and it works like this the brass piece has a tapered end inside it to center it on the balancing base Pin insert the brass slug into your Prop and then set it on the balancing pin on the base, sitting on your bench use a 6 inch precision scale to measure from the bench to a known point on the Prop blade tip, then rotate your next blade to that same point that you measured from on the first blade  etc., for each blade

I sand the end of the blade to get a good balance I hope this helps anyone with Vibration Problems
if you dont have a Lathe to make your own I am willing to help anyone on the list at cost of materials

How did you create the taper inside the brass part?

Just curious.....I also have a Lathe but am just a Novice.

I like your method....reminds me of an RC model balancer.

I used a 45 degree de burring tool to finish the inside taper to a sharp point in side
