Well... there was actually a misheard comment that went into the mix. Shortly after this intern tried to cut her hand on the diagonal the master carp asked to have her removed from the shop. "She's not exactly a rocket scientist," he explained. "Actually, she is," was the reply from the artistic director.
I hasten to say that I know very good theatrical carpenters of all national origins, ages, sexes (around San Francisco, we recognise at least six), backgrounds, and academic credentials.
But power tools seem to be one of those things you either "get," or you don't. (Another famous case...a director who borrowed a finishing sander. "Where do you hold it?" he asked. Um, on the part that doesn't try to sand your hand down.)
And now, back to our regularly scheduled thread.

Please don't copy magazine or newspaper articles into the forum. Thanks.

"Cheer up!" they said, "It could be worse!" So I did, and it was.

Sorry: I'll delete it and send it to Lenbrazil in a PM

Thanks. I don't mean to be a jerk or anything, I just don't want the forum to be shut down or something.

Not a problem: I know from other hosts that ProBoards can be rather touchy; I should have thought to put it in a PM originally ;D

Jay [or others] what do you think about the claim that without electrical power the props of the King Air would stop spinning? Didn't see an answer to this skimming through... The ignition systems on all piston-engine aircraft (possibly excepting non-standard craft such as ultralights) are dual-magnetos (2 complete systems in parallel, each cylinder has 2 separately driven spark plugs!), so they do not depend on main bus power. Main power is for radios, lights, and some guidance equipment. Other equipment is driven by engine vacuum, so there is yet another redundancy for safety. And of course, some equipment needs no power -- altimeter (ambient air presure), speed (ram pressure), compass (if I need to explain that one... ;D). Retractable landing gear may be electrically driven, but will always have a mechanical backup too. (I do believe there are now some electronic ignition systems available, but they all have a magneto failsafe in case of power loss.)

Isn't a King Air a turbo-prop not piston?

No: the turboprop is a gas turbine: instead of exhausting the efflux to provide thrust as in a turbojet or turbofan, sufficient turbine stages are added to drive a propeller.

Isn't a King Air a turbo-prop not piston? My mistake. I had done a Google to check in this (I've not flown anything larger than a Cessna 320), and must have misinterpretted or gotten a bad link; maybe a typo, when I try it now the links all agree on turboprop

Ok, read up on turboprop ignition systems to see how they compare. You're gonna love this... The ignition system is only used to start the engine; the flame in the combustion chamber is continuous after that, much like lighting a propane or oxy-acetylene torch. Of course saying 'only' isn't exactly correct, it can be used to restart the engine if it cuts out for any reason, such as running out of fuel on one tank before switching to another. A side note, these ignition systems are shielded -- to keep the ignition from interfering with the radios For more detail: www.globalsecurity.org/military/library/policy/army/fm/1-506/Ch6.htm
