Every few years I run across the same sandpaper cutting jig in woodworking magazines’ Tips and Tricks section. While the design may vary, the concept is always the same; screw a hacksaw blade to a piece of wood and use it to cut sandpaper in half.
I made this jig twenty five years ago and I’m amazed that nearly every time I see it in a woodworking magazine, it wins Best Tip. I originally saw this jig in a book called Making Woodwork Aids & Devices by Robert Wearing published by Sterling Publishing Co. which is a great book on making jigs and fixtures for your shop. It’s so good, the publisher released a third printing of the book a couple of years ago. If you don’t own this book, buy it!
The concept is so simple, you may feel dumb you didn’t think of it yourself. Basically cut a piece of scrap wood that is half the width of your sheets of sandpaper. Then draw a line down the wood that is half the length of your sandpaper.
After cutting the paper in half, stack the sheets on top of each other, turn it 90 degrees and line up the end with the pencil line and rip it again.
Viola, you have four equal sheets of paper, perfect for a 1/4 sheet palm sanders or for hand sanding. Go ahead and send this tip to your favorite woodworking magazine and win a set of Bosch power tools for Best Tip. You can thank me later.
