Consequences of replacing heavy alluminum Prop with lite weight wooden prop?

[1600vw]

Getting back to your original question, you need to understand that prop pitch is usually measured at a certain percentage of the blade length and the pitch (blade angle)changes continually through it's length. If your aluminum prop was shortened then the original blade angle at a percentage of blade length is no longer accurate. Some prop makers measure pitch on the rear face of the blade and some use the cord line of the blade airfoil. different prop makers may use different blade airfoils so this is another area for pitch measurement to differ for the same affective pitch.
Ed Sterba built me a couple of props over 30 years ago when I was flying a Sonerai and as good as he was then he can only be better now. Personally, I would consider asking anyone else for advice concerning a Sterba prop a waste of time. I don't mean any disrespect toward the posters here, but no one knows props on Sonerais' any better than Ed.
I would agree that the clipped metal prop is a wall hanger.
The change will have an affect on your weight and balance so adjust accordingly.

As I stated before this post is not about the Sterba prop but about what the reduction in weight will have on the engine.

As for W/B I post this will be done and ballast add or removed as needed.

This old prop was sent to a prop shop. They cut and repitched this prop. They put the length on the hub but not the pitch. They also put on this hub this prop has been reconditioned.
