Piston clips?

The price is not the factor. The ones I have just taken out,( provided they are not damaged) have proved to be up to the job. I can't guarantee new ones till I have done several hours at full taps. Sound strange, I used to fly Microlights and the book said to change plugs every 50 hours. That was till one day, I put a new set of NGK in and found one to be faulty. Ever since then I have trusted my own used plugs over new ones, provided they were in good condition and only changed when they looked tired. PS I wasn't the only one experiencing these problems.

Has anyone used aluminim bullets instead of circlips before?

If you mean alloy plugs that are fitted to the ends of the piston pin. Then yes, back in the old days they were sometimes used in slow reving engines, still wore groves in the cylinder though, and not to good with 2-stroke ports.

Still seen in aircraft engines like this 2,500 rpm Lycoming, check page two........ http://www.lycoming.textron.com/supp...fs/SI1267D.pdf

Far more likely to find a faulty new circlip than one you've removed (without fucking it). They're just spring steel guys, they don't actually wear out y'know.

Used to make teflon buttons for some builds, where circlips were known to be a problem at high revs. Really only good for engines you're stripping fairly regularly.

....Marsheng and Ocean1 have the answer....

I'm ashamed to admit that in my young stupid and impoverished days when I was rebuilding RD engines out of the box of bits in the shed with no new components used at all I did on ocasion make my own piston circlips by cutting up key rings, dodgy as hell in hindsight but never had one fail.

aluminium bullets? nah that's silver bullets if you want to kill the vampire. Not sure what you'd use Aluminium bullets to kill, perhaps something soft like a charted accountant.

I thought silver bullets kill werewolves, maybe they kill vampires too, Very clever things if they can multi task....................just like women....................

oh yeah, yer probably right. Despite all these silly vampire programs on the telly I'm not up to play with the mythology, I think I'd rather watch another cooking program. Actually I'd rather turn the telly off.
