My dual drum sander came with 5" wide sandpaper on its drums. The drums are
5" diameter. I couldnt find 5" paper in stock so I bought some (a lot?) of 3" paper. The problem is that when I wind the paper around the drum it doesnt line up to the slot on the right hand end the way the original 5" paper did. I can't get the end trimmed properly to get it into the catch. I think I must not be cutting the start side to the proper angle although the paper is winding on at about 45degrees which looks like a good angle. Is there a template for cutting different widths of paper or do I just have to experiment and waste a lot of expensive paper?Tom in Victoria
