Replacing Colin Walker wood prop with Sensenich aluminum on 1991 RV-4
I have an older RV-4 (1991). I'm having to replace my Coin Walker wood prop and have just received my new Sensenich aluminum prop. The old spinner (12" diameter) doesn't fit the prop tightly. There are gaps where the blades exit the spinner. Van's replaced the 12" spinners and back plates with 13" in 1995. If I can't make the old spinner and its accessories work, what are the best options for a new spinner?
