    BalanceMaster testing

    Sure did, Mark. I don't want to bother him any further, especially after my bank fouled up a money transfer. It would be quicker to make up six washers to centre it. Good idea, BA, but doing that accurately is beyond my equipment and skill.

    Interesting, Callahan. I've also heard that from a mate who has a lifetime of experience with aeroplanes. He offered me his old balance ring, but it's filled with ball bearings, not mercury.

    No Bruce, I don't have any sort of vibe measuring instrument; I'm happy to rely on the difference in feel and sound. The newest to an objective measurement I'll have is my paper flight plans which I fill in as the engine is warming up. Going back thru a decade of them shows a noticeable change in the my writing- or maybe it's just Parkinson's...

    Thanks Mark, but that was never my intention. I want it against the front of the prop. My problem is how to ensure its well centred.

    BalanceMaster testing

    In my Jab installation, an alloy crush plate fits in front of the prop; Belleville washers and a nylok nut fit over each bolt, If I put the BM between the crush plate and the prop, I need 6 well-fitting washers to centre it. If I fit the BM outboard of the crush plate, I'd need wider washers over it and under the Belleville washers, leaving me precious few threads past the nylok nut. Which is better?
  6. So true, FB. I knew a young bloke who shoehorned a Kawasaki Mach IV (750cc) engine into a Mach III. The standard frame could barely handle the lethal power of the 500cc engine. Shortly afterwards, he ended his days on a fast corner on the Pacific Highway not far south of Kempsey.

    I asked for it to be drilled for my prop, but it never occurred to me that I'd need to mention I wanted to mount it in front of the prop. Good point, OT. That's what I plan to do, because I'd be lucky to find washers of the same thickness, let alone size. I presume there's no reason I can't use aluminium sheet if I can find one the same thickness as my BM plate.

    I'm about to fit my new BM on my Jab 2.2. It has been drilled with quite large holes, presumably to fit over the prop drive lugs. Based on discussions on this thread I plan to mount it in front of the prop, where the 1/4" bolts poke out. I plan to fill these large holes with thin washers to accurately centre the plate. Anyone see a problem?

    Corby Starlet Wanted

    There was a nice wooden home-built for sale at Cessnock a few years back. An impressive French design (but not a Jodel) from a deceased estate. Worth contacting the club.

    CASA set to "fix" community service flights

    When our government tore up the "two-airline agreement" city people got cheaper flights, but rural people were the losers. Heaps of little towns lost their regular air services, oft used for medical reasons. Public transport services have also been reduced, putting more people on the roads. Now crazy bureaucrats want to bugger up a common-sense, grass-roots alternative.
  11. Agreed, Dean. Even gyros with "normal" paint jobs are very hard to see.
  12. I guess we'll be able to add an electronic noise generator to make our silent plane sound like a Merlin or big round engine...
  13. -except that a cabin heater has the potential to be the most dangerous item in the aircraft. Just make damned sure that you heed Kaspar's warning. It's so easy for CO to get into the cockpit, especially if your heat is coming from an exhaust shroud. Even tiny amounts of CO can kill you, because it displaces oxygen in your blood. CO detectors (not the silly credit-card seized ones) are not expensive.

    Qantas at war

    I've read a Japanese account of that action which mentions they lost at least one Zero pilot on the way home to Timor because of fuel lost thru bullet holes.

    Going bare

    Another aspect of footwear: could it hinder your escape from a prang? I favour elastic-sided boots as they are fairly easy to slip off if caught.
