Yesterday I was reminded, yet again, that I am not the brightest bulb on the tree. This time it happened as I was changing paper on my drum sander. I use the drum sander frequently, so changing paper is not an uncommon task. That said, when I rolled the new paper on I was way off when I reached the other end of the drum...so I repeated the task...and once again it was off. At this point, I was certain that the good folks at Klingspor had mislabeled the box, but when I compared the new roll to the roll I had just removed it lined up perfectly; so I tried again...no luck! As I was looking at and fuming over the situation it suddenly dawned on me that I should try rolling the paper in the other direction....SUCCESS! On reflection, I am not too surprised that I rolled it in the wrong direction initially, but what is really irritating is that I didn't immediately recognize the problem! (I apologize to my friends at Klingspor who may have experienced some negative vibrations yesterday afternoon!)
