OK, Anyone got any advice or opinion on this? I counterbored the hub on a Master Airscrew 3-bladed 14x8. I did this to accomodate reaching in to a short shaft with the prop hub nut. Question is have I weakened the prop hub by cutting down into the "spokes" of the hub?? Here is what it looks like now.
