Hello Willie, thanks for the response. I enjoy all of the topics on the forum and never stop learning different tidbits of information regarding a host of different items. It's also good to experience different points of view and perspective regarding various situations. There are truly a vast cross-section of respondents on the forum and they all bring a lot to the table and you are right, many folks don't often think about the little things that go along with the welding and fabrication trade and I think that it is good to make that information available to hopefully save somebody some possible grief. Have a great day and Regards, Allan
