Cstevec,
That was my origional Plan. So went to my workshop and installed the spinner and prop I used a 12" cressant wrench and tightned the sh%t out of it. The next day I took it apart to see if the knurling embeded into the prop and it did so I proceded to Tighten the Sh%t out of it agian. Well I did two things wrong #1 I did not have a metal washer between the nut and aluminum prop washer and #2 The stud was not enguaging enough threads fully and I striped them. It would no longer tighten. I desparatly headed to Home depot and on the way gave Keith at BME a Call. I was going to find a longer stud and retap the engine.
I wanted to go to the 6 bolt but the 6 bolt has a 10mm shaft and I had already drilled 2 Mejzlik 28x10's and my spinner backplate 7/16". Keith offered to replace the Hub with a 6 Bolt and custom make me some bushings so I could use my prop and spinner as drilled. He is also sending me a new stud bolt and prop washer. And all I am paying for is the 6 bolt Hub...Now that is customer service!
