Cool thanks, Google is the smartest invention since the thermos. I do kind of miss going to the library to do research but would take a day and and the LA and San Diego Library's were full of homeless people so it was entertaining.  

A coworker asked me the other day what are the best tools for mechanical design. I said the experience of other coworkers, especially the ones that make the stuff and Google to help weed out who is full of it when your not sure. LOL.
