An Oldie But Goodie - Sandpaper Cutter
For those without a paper cutter, or who don't want to use it or scissors, this simple-to-build cutter I borrowed from a magazine fifteen or so years ago is a must have shop fixture for me. It cuts sand paper for my quarter sheet sander quickly and well.
To make one, you just need a piece of plywood a little bigger than a standard sheet of sandpaper, a couple flat washers, a couple screws a hacksaw blade, a felt tip marker and a standard sheet of sandpaper.
1) Secure the bandsaw blade to the plywood at the center of the plywood, as seen in the picture. One flat washer should be installed between each end of the bandsaw blade and the plywood. This will give enough room to slide a sheet of sand paper under the blade.
2) Draw two lines at top to bottom and left to right between exact centers of the sandpaper, splitting it into four, each of which would fit a standard pad sander.
3) Slide the sandpaper under the blade (it will only fit lengthwise, at this point) until one of the lines lines up with the teeth of the blade. Hold the paper in place and trace around the lower half of the paper (below where the teeth are).
From now on, when using the cutter, you merely push the paper up under the blade until it lines with this line.
4) Still holding the sandpaper from moving, reach to the top right or left and lift and pull down on the paper, so the part at the teeth of the blade are pulled against it, ripping the paper across the blade.
5) Now take one of the two resulting pieces and, again, line up the line you drew on the sandpaper with the teeth of the blade. When in position, again trace around the paper.
6) For the final cut and, again, while still holding the paper in place, lift the upper edge of the sandpaper and pull it down across the teeth to rip it.
You should now have three two sheets of paper that fit your pad sander. Just repeat the process to, quickly, cut more sheets for the sander. I find I can cut two sheets at a time.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
