The belt attachment is what makes it far superior to an ordinary spindle sander. Belts have a far greater working area than the small cylinders most spindle sanders have. They last longer and are cheaper to replace, and are available in a wider variety of grits. The #36 belt is ideal for removing material to make a rough shape, then clean up with a #80. The big end of the belt drive is a 2-1/2" diameter, which turns out to be by far the most useful part of the machine, and exactly matches many of the curves on a Fender neck. Of course, there are smaller spindles all the way down to 1/2" for tight spots. The flat on the belt will cut reasonably straight for small parts that fit entirely in it, but anything that overhangs the ends is going to be gouged by the rollers unless you are very careful - light touch and always moving the workpiece. It's good exercise.
