    I'm presently running with no attachment to the front spinner plate. It is still there however. I'm using a three blade Catto prop and this is the way that Craig Catto indicated would work just fine. So far it does and the spinner looks great without extra holes. My last prop was a Sterba and I had to shave about .125 from the front of the prop hub to make the spinner fit. Was too tight and the same problem I think your having.

    Pat, MHWH tape layered underneath the spinner on the bulkhead helps too. I still like having screws through the spinner into the bulkhead, I have seen an RV4 that lost the spinner inflight, cracked the canopy as it went by the cockpit and hit the tail hard enough to feel it in the stick. Flush SS look fine... RR PGLong@aol.com wrote: I'm presently running with no attachment to the front spinner plate. It is still there however.

    Ivan, don't run without a front spinner bulkhead, you will lose the spinner... RR "H.Ivan Haecker" <baremetl@gvtc.com> wrote: After 14 years and 1300 hours of running my Sterba 68x72 prop on my -4, I have decided to try something with a little more pitch. My new 68x78 Sterba arrived and off came the old prop . Surprise, the front spinner bulkhead is cracked again. This has been an ongoing problem for me despite making it fit like a glove with flox and resin a few years ago. So I have a new one from Van's (9") and surprise (again), it doesn't fit . This time, instead of being a little too small, it is a little too big. Just enough to stop the spinner from going on all the way to the edge of the rear bulkhead to line up the screw holes back there. Pushing harder just won't do it. So my question is: Has anyone tried running with no front bulkhead? Anyone know of a source for a slightly smaller bulkhead? Any other ideas? Thanks, Ivan Haecker -4 1300hrs S.Cen.

    Pat, I believe you are right. I talked to Sterba today and was told the prop should be 4 3/8" thick. However mine is about .060 more than that. How did you shave some material from the front of the hub? I would think it important to keep the front parallel with the back. Today I tried sanding the inside of the spinner to remove any high spots and was able to force it on, but it is still very tight! Maybe a day sitting out in the unrelenting heat around here will fix it. Ray, you and others have me convinced. No running without a front bulkhead!!
