I have a couple of props that have been chipped and/or worn on the tip by contact with a hard surface that I would like to cut down about 1/4 inch... What concerns should I have in doing this... Not wood props... Thanks...

Try to keep it as smooth and even on both sides as possibe

Rebalance!

The problem with a prop that has clipped the ground is that there may be a difficult to see crack running toward the hub center. Obviously, this could cause a catastrophic fault when the prop comes apart, sheds from the crankshaft and then shaft runs the engine. New props can have such problems too. It is best to go over ALL wooden props with a magnifying glass while applying torsional force to the prop blade (with the hub held solidly). Don't get too carried away with the torsional force being apply. We don't want to break a good prop!

Hi!
It's just filing and sanding!
No problem in any way of modifying any prop as long as you know what you do.

1. Always file and sand on the front side Curved side) otherwise you might change the pitch .
2. Keep the blades as thin as possible.
3. Don't be afraid to do drastic modifications...how do think they made the prop in the first place???
4. Thin and long blades is better than short and thick.
5. Always balance your prop after you have modified it

Thanks to all for the information... Richard

Remember to always re-balance any prop that you have modified.
