Boy o boy! I go in to work for a few hours and this thread explodes. I echo Pete and Charles as a firm believer in the personal 'logicly unexplainable events but I was there and saw it for myself' episodes. I just know there's a pony under that pile. Its a pure pleasure to be among such company of avid seekers.
My twingle is associated with anything to do with pipe organ pieces, late 1800s Quack boxes and medical devices and of course, anything mechanicly/electrically intriqueing. Perhaps some of my re-routed brain circuitry responds to the faint residual halflife neutronical emanations - yeah, I made that word up.
I credit the twingle to all those electric sockets I thrillingly stuck metal objects into to complete the circuit from tothood to adolescence. I 'learned' about the resistance...and flamability...of various materials in this way.
And there's that 'since I'm the only one who's thin and short with blue eyes in this family I must be a foundling' thing.

This is absolutely not true, of course, and I was showered with buckets of love & encouragement by Mom & Dad but early on I set out on a differnt path than the family saw coming...
I tell few about my interests because once started I reach a fever pitch of enthusiasm for the subject and most listeners glaze over and politely excuse themselves. Its enough to just take something unfixable and return it to them fixed. But get two kindred folks together and they have no need of social indulgence from 'standersby'.
Trained as a mechanical engineer, its more the decades of taking things apart and putting them back together that keeps an open mind to stuff that ain't in textbooks.
The family story is how Davy got a tinplate flying helicopter attached to a hand crank by a long spiral cable for his 5th Christmas. Just would not play with anything else all day. When it stopped working I took it apart after dinner in my room useing things from Mom's sewing kit and fixed it.
Then there was my dear cat Austin ( who looked like no other cat in the neighborhood) who crossed the road in front of my car on my way home and paused on the curb. 1 minute later I pulled into the driveway up half a block to be told by the neighbors that he had been struck & killed by a car 3 hours earlier. That was 15 years ago and since then all my kittens to cats have been indoor or outdoor on the screened porch only.
and so it goes...
Thank you for sharing the stories and links. Dang, how did I miss that white & gold polisher?
Dave
