Belt sanders are highly versatile tools that make woodworking and metalworking easier and more efficient. They come in a range of types that include:
Belt file sanders are handheld machines that use smaller, narrow, sanding belts. These machines are ideal for working in tight areas or removing welds from corners.
Floor belt sanders are manually operated to sand wood floors.
Tube belt sanders consist of a pulley system that contours the sanding belt around tube-shaped surfaces.
Portable belt sanders are great for smoothing and finishing small pieces and large surfaces, like decks and floors.
Stationary belt sanders can be bench-mounted, pedestal-mounted, or even mounted on a stand.
Regardless of which machine you use, applying the right sanding belt is essential for performance.
Sometimes this requirement causes issues, especially if you’re using someone else’s sander or it has been a while since you had to change belts. If you don’t know what size belt you need, how do you perform an accurate measurement?
Start by trying to locate the product manual, which should indicate the correct belt size. If you no longer have a hard copy, most manuals can be found on the manufacturer’s website. Should you be unsuccessful, the team at Red Label Abrasives has some practical tips for accurately measuring a sanding belt, so that you know what size you need moving forward.
Method 1: Double Measurement Method
If your belt is smaller, press it down flat on a hard surface and measure it from end to end using a tape measure or string. Double the length and you’ll have a good idea of the belt size you require.
Method 2: Cut and Measure
If you have an older belt, cut it so that it turns into one long strip, then lay it flat and measure the total length. This technique works with belts of all sizes.
Method 3: The String Method
Take a piece of string and wrap it around the sander in the same way that you would apply the sanding belt. Cut the string where it meets and then measure the length to get the belt size.
Method 4: Rotation Method
Using a pen or marker, make a small mark on the inside of the belt. Then make a corresponding mark on the floor or a flat surface like a counter or benchtop. Slowly move the belt through a full rotation until the mark on the belt once again touches the surface, and then mark the touch point. You will get the belt length by measuring between the two marks.
