When I worked with my dad at R.F. Communications (now Harris Corp.) in the late 70s, he showed me how to draw an arc off an antenna coupler with a pencil. When I was even younger he'd shown me how to draw an arc off a TV flyback with a grounded screwdriver. I developed a really healthy respect for high voltages before I went and got walloped on my own. Auto spark coils...they were just good fun.
I still remember my dad melting a spot on the shaft of a screwdriver after he was messing around in the fuse panel in the basement. Or the time my buddy and I melted a half-moon into the sheet metal when we disconnected the positive battery cable in his Citation and the ratchet touched the fender lip inside the engine compartment.
Part of his still is looking like he doesn't know what he's doing, but in reality knowing that nothing he's doing is going to cause short term damage. Long term damage may be another story.Ah yes. A lot of his stuff is gut-busting funny but I don't know how he's not dead... Love it.
