The Murphy Builders Site

Hi Wayne

Believe or not, the first time I heard of that is when I read your post
about
the subject several years ago. I took that advice to heart and made
certain
that the rounded side of the washer was always against the metal. It only
makes sense that the sharp edge of the washer (hard) would cut into the
softer metal.

Wayne, there are many other tips and suggestions that you have made
through the years, and just want you to know that some of us actually take
note. I (we) appreciate your help and input. You've seen your fair share
of
the mistakes of others.

Gilbert
