The Use of Random Orbit Sanders Without Holes in Sandpaper: Considerations and Alternatives

Is it possible to use a random orbit sander without the holes in the sandpaper? With the right considerations and alternatives, you can still achieve effective results. In this article, we will explore the possible scenarios and the implications of using non-perforated sandpaper.

Dust Collection

The primary advantage of the perforated sandpaper in a random orbit sander is its ability to facilitate dust collection through the sanders vacuum system. The holes in the sandpaper allow for the efficient removal of dust particles, which in turn extends the lifespan of the sanding media and reduces overall sanding time. Without the holes, dust may accumulate on the surface and within the sander, potentially leading to clogging and reduced effectiveness.

Sanding Efficiency

Using non-perforated sandpaper may lead to reduced sanding efficiency due to restricted airflow. This restriction can cause the sandpaper to overheat, leading to reduced cutting action. This can significantly impact your sanding process and the overall quality of the finish on your workpiece.

Surface Finish

A significant consequence of using non-perforated sandpaper is the effect on the final surface finish. The lack of holes means that more dust particles may remain on the surface, which requires additional cleanup. This can disrupt the smoothness and polish of the finished surface, leading to potential imperfections.

Compatibility and Alternatives

It is essential to ensure that any non-perforated sandpaper used is compatible with your sander's pad. Some sanders are specifically designed for perforated paper, and using non-perforated paper may affect its adherence and performance. If you choose to use non-perforated sandpaper, you can still achieve effective results by incorporating alternative dust collection methods.

Alternative Dust Collection Methods

Dust collection is crucial for optimal sanding performance, even without the holes in the sandpaper. One effective alternative is to attach a shop vacuum to the sander. This method can channel away the sanding dust the tool creates, extending the longevity of the sanding media and significantly reducing sanding time. There are several ways to achieve this:

Attach a flexible hose to the shop vacuum and position it close to the sander. Invest in a dust collector system that can accommodate the sander. Utilize dust shrouds or collector systems designed specifically for sander use.

Historical Perspective: An Old but Effective Sander

Despite the challenges, many seasoned professionals continue to use random orbit sanders with non-perforated sandpaper. For instance, the half-sheet sander, now 33 years old, is a testament to the sander's durability and effectiveness. This sander, known for its bag pickup, offers similar dust extraction capabilities as modern models. Equipped with a plastic skirt, the sander can efficiently remove dust, even on heavier materials such as wood. However, for finer work, it is best to use very fine grit paper and apply minimal pressure to avoid compromising the delicate finish.

While the use of non-perforated sandpaper is possible, it is generally recommended to use the appropriate perforated sandpaper for optimal performance and results. By understanding the considerations and employing effective dust collection methods, you can still achieve high-quality sanding outcomes.
