The bobbin/spindle sander is an oscillating sanding machine which is made to help the user to achieve a smooth, flat finish to wood pieces, which are intricately shaped or possess curved edges. Traditionally, woodworkers would have to create jigs and wrap sandpaper on a wooden dowel to rub away at the extra material. The oscillating bobbin/spindle sander has a rotating cylindrical drum which once covered with the required abrasive can enable it to smooth out saw marks, rough curved edges, and inside hole cuts.
In addition to steadily rotating the spindle, the bobbin sanding also moves the drum up and down during the rotations. This movement helps to prevent static friction, which can cause burns and band marks on the wood pieces as they are being worked on. This movement is also helpful in increasing the life-span of the sanding sleeve by spreading the wear across a wider surface area.
Bobbin/spindle sanders are available in a variety of sizes, some of which are floor mounted and can stand alone, others which are mounted on a benchtop and even jigs which you can attach to a drill press. The bigger, floor-standing models are more expensive and better suited for more industrial workshops.
Today, we explore the range of oscillating spindle sanders which are available to the woodworker right now. Since the departure of Triton Power Tools from the South African market, the range of bobbin sanders available to the home user has since been largely shrunken. Gone are the days of an oscillating bobbin sander which costs less than R 5 000.00. These have now become quite an investment. Luckily, however, the remaining suppliers of these machines are amongst the best in the industry.
