Sam, I used my old out-of-balance aluminum spinner as a mold to make a new one out of fiberglass, and it works great. Far lighter, and balanced much better (with no effort from me). Excruciating details are at http://www.n56ml.com/spinner/index.html . You can make one of these things in just a few hours. Use the same aluminum backing plate but with your new fiberglass spinner (it just slides on a little further, and tightens right up). I also made a front plate for it, but have to admit that I've been running another one on N891JF with no forward plate, and it's as tight as ever with >400 hours on it. Just push it in place really well when match drilling the holes, or put a thin shim in during match drilling, then remove it for spinner installation, and it will tighten right up. It's so light the rotational forces on it are minimal. Be careful to keep it centered, by rotating the prop with a pointer nearby to check the runout of the pointy end. I've seen a lot of scary off-center spinner installations, but mine is not one of 'em! This kind of stuff is perfectly legal for you to do yourself. It's just the condition inspection that has to be done by an A&P.
