Another 'bit' from my last week's work on the plane: One tip of the wood prop has about a 3" crack in it going through all but the last outer ply 'skin' on the back of the prop.
It's a 53" prop, on an 1835 (presumably HAPI) VW. 1) Is repairing such a crack safe/economical, and if so, how does one go about doing it? 2) What is the 'normal' range of prop dimensions for a KR-2 with an 1835? Eg, how do I determine what to replace this prop with, if fixing it is out the window?
