Geez why all the concern over "experts" it is just a word. If this word somehow intimidates some then I suggest you toughen up your skin. We as a forum can easily proclaim our own experts from our manufacturing, designing members here.
There are some here who just know more or have experienced more. No one is preaching or telling anyone anything. If a question is asked by a member "Our" experts chime in. Then a discussion is initiated with "All' for their input.
IMHO Dave, Steve, Hal, Scotty, Bill are experts to me.
If a member believes they are an expert in their own mind and do not desire advice of any kind avoid the thread, easy peasy. Do not ruin it for the rest of us. No agenda here but good will.
