68GTXMan, now there's an engineer who has enough self confidence to know that no one knows everything. My son is currently studying to be a mechanical engineer, I hope my son always has enough brains to know that he can never know everything. Sometimes the old timers (and sometimes younger folks) know a better way. And sometimes it doesn't even make sense...BUT IT WORKS!!! Of all things man has created and accomplished, the only things anyone cares about are those things that actually work!!!
