Prop Repair

Here are a couple of shots of how I repaired a broken prop. A bolt came off of the muffler, and flew through the prop,
and straight out the side of the thrust duct.

I cut the damaged sections out with the table saw, and tried to make the cut as square as possible, so that I could glue the plugs in.

Then I sanded off the excess, and glassed balanced etc. The amazing thing is how well the prop worked when it was damaged.
This is probably because the damage was more central, and the majority of a prop's power comes from the outer 1/3.

I have yet to invest in some leading edge tape, as evidenced by the erosion at the tip.
