Hi, A friend of mine gave me a metal propeller. The propeller is 70.90" from tip-tip (leading edge - leading edge) , 34.00" inches from hub-tip (tip of propeller as in "leading edge"). The propeller has some damage and I was wondering if I can re-balance (if that word even is a word) the propeller: Leading edge is "dented" - 15" from the (right hand side) leading edge of the propeller, small dents can be seen. -11.50" from the (left hand side) leading edge of the propeller small dents can be seen. -Left (hand-side) leading edge is dented (a bit...very small damage to that side) -Small scrathes (barley visible) can be seen from the hub of the propeller to the leading edge. That's what's wrong with the propeller. I want to restore it and put it on an ultralight. I've worked and fixed wooden propellers before but this one is METAL; what do I have to do in order to restore the propeller and make it run NORMAL again? thank you.
