2 Rivet Questions!
I have noticed that most of my exterior rivets are polished and I cannot see the interior 'stem' of the rivet. However, some of the 'polished' rivet heads show the interior 'stem' rather well under magnification. I suspect these are 'replacement' rivets as I see them primarily around a window frame. Does this mean that these actually are rivets that were replaced and not original 'factory-installed' rivets put in at the time of construction? Also... when removing 'belly pans' to do repairs, why re-install rivets under there rather than using stainless steel sheet metal screws to enable future access? Do the rivets add to greater structural integrity versus screws that may loosen up over time? Would aluminum screws be better than stainless steel screws? Or is re-riveting it not only the correct weay, but actually the best way to do the job? I believe in the old adage that says something to the effect of... 'if you haven't time to do it right the first time, when will you have time to do it again?' So, I want to get this right the first time!!! Tom
