Thank you all for your input, especially Craig for all of the alternative links
and to Pete who passed my email to GRT - and guess what, I had a response from
Sandy! It's good to know that some of you have had a good response to their
queries/problems. It gives me more confidence.
I now need to sit down at my computer and calculator and work out what's going
to work best for me - I'll let you know how I get on.
Thanks again.
Ian

| Subject: | Re: Rotor arm pictures |
I'm wondering why Jabiru makes a different rotor for the two engines.
The 3300 one looks a LOT more substantial in that the length of the
skirt is longer and thus grips the shaft a lot better, I'll bet.
I've been thinking of making my own rotors for awhile now, or at
least modify the skirts of existing ones. If my present method of
drilling holes in the skirts and using epoxy doesn't hold for at
least 200 hrs, I will.
When I was racing cars, I used a Vertex magneto, and their rotors had
3 point-tipped screws in the skirt. These pointed screws went into a
v-shaped groove in the shaft, and were safety wired in place. No lost
rotors at 6500 crank speed, but then it would have taken several 8-
second dragstrip runs to accumulate 200 hrs. : )
