Jerry, I think the main thing about your forum, is it is educational. I see things on it which I struggled with when I was a kid. I know where most of the guys who ask questions, are at, because I have usually been there doing similar. One thing I always do when I am at a race circuit is, i always help people who are struggling, even if they are my major competition. If they go faster they help me go fasster, just by going faster. When you race, all the speeds are relative, once you are in a dog-fight. What you lose on the merry-go-round, you pick up on the hurdy gurdy ?
The thought that I might help people such as NIgel win races, really inspires me. I don't know much, but what I know, he is welcome to - 'Information was meant to be free'.
I spent my life as a scientist in engineering factories working on materials and process, quality and safety. What we made was usually designed to kill without killing the killers.
