Spindle Sander

The spindle sander is used to sand inside (concave) curves. The spindle rotates while simultaneously oscillating up and down. This helps keep the abrasive from loading up and overheating, which would happen if the spindle did not move up and down. Various spindle sizes can be used on the machine to accommodate different work radii.

1. Always use the largest spindle possible for the radius being sanded. Using a smaller spindle makes it more difficult to get a smooth curve, takes longer, and results in excessive abrasive wear.

2. Always feed against or into the direction of the spindle rotation.

3. Avoid excessive pressure on the spindle. Too much pressure generates heat and will quickly damage the abrasive.

4. Use the throat plate that leaves the smallest opening around the spindle.

5. Hand-tighten the spindles only. Do not use wrenches to tighten spindles; this can result in the spindle becoming stuck in the collet.

6. Every component of the spindle sander has a home on the tool rack. Do not leave spindles, throat plates, or wrenches lying around; return them to their proper location in the tool rack.

7. Notify the instructor if the spindle abrasives are excessively worn.
