Ok, let me add a little fuel to the fire here. How many of you that balance your props after it has been reamed and balance them in more than one orientation? You can count me firmly in the camp that balances their props and I go one step further. After the prop is balanced so that it hangs level I then rotate it 180 deg. and see if it still is in balance. Sometimes it will try to rotate back to the previous orientation on it’s own. If it does this I then drop it in the trash. I have tried to correct this out of balance problem by drilling holes in the hub and using CA and filling with solder but I eventually quit this practice. The cause of this kind of out of balance condition is most often caused by the hole not being reamed correctly.

What I would really like to do is to find a way to accurately orientate the prop relative to the crank so as to aid in balancing the engine similar to the harmonic balancer on the old Chevy 454. Does anyone have any ideas on how to do this?
