Subject: Pietenpol-List: corvair - prop recommendation and machine workTwo questions for the group.I'm building the long fuse with a corvair motor - typical William Wynne conversionwith front starter and alternator. Any recommendations on what prop to use.I'm considering the warp drive prop but hoping I could find a wood prop forless money that would do the trick.Also - people in Minneapolis area - any recommendations on where to have corvairmachine work done?Tom BrantBrooklyn Park, MN________________________________________________________________________________Date: Thu, 15 Sep 2005 19:27:14 -0700 (PDT)

All I heard is that the cranksthat were breaking all had prop extensios which against recommendations... I sent my crank to WW for machine work - That way I get the grinding, mod for thesafety shaft, hybrid studs all in one shot.. Plus, I know it will be doneto his standards and don't have to second guess.Will check out the place you mentioned - thanks.Tom B.________________________________________________________________________________
