Putting sandpaper on a disc sander typically involves preparing the disc, aligning the new sandpaper, and pressing it firmly into place.
Replacing the sanding disc on a disc sander ensures optimal performance and smooth finishes on your projects. The process is straightforward, particularly if you are using sandpaper with a pressure-sensitive adhesive (PSA) backing, which is common for many workshop disc sanders.
Here’s a step-by-step guide:
Preparing the Disc Sander
Before attaching new sandpaper, it's essential to prepare the sander itself.
- Safety First: Always unplug the disc sander from the power source before you begin.
- Remove Old Sandpaper: Carefully peel off the old sandpaper disc. If it has a PSA backing, it might require some effort.
- Clean the Disc: Remove any adhesive residue left on the sander's disc. You can use an adhesive cleaner or mineral spirits, following the manufacturer's instructions for both the cleaner and your sander. A clean surface is crucial for the new sandpaper to adhere properly.
Attaching the New Sandpaper Disc
Once the sander's disc is clean and free of debris or old adhesive, you can attach the new sandpaper.
- Choose the Right Sandpaper: Ensure the new disc is the correct diameter for your sander and the appropriate grit for your task.
- Peel the Backing: If using a PSA disc, peel off the protective paper backing to expose the adhesive layer. Handle the disc carefully by the edges to avoid touching the adhesive surface.
- Align the Disc: Carefully align the new sandpaper disc with the sanding disc on the machine. Precise alignment helps ensure the sander runs smoothly and is balanced.
- Press into Place: Once aligned, press it down it'll stick pretty much right. Away. Apply firm, even pressure across the entire surface of the disc to ensure full contact with the adhesive. You can use a roller or a block of wood to help apply even pressure, starting from the center and working outwards.
- Reassemble: If you had to remove any components like the table or guard to access the disc, now we can put everything back on.
Tips for Success
- PSA vs. Hook and Loop: While this guide focuses on PSA discs based on the reference, some sanders use hook and loop (like Velcro) systems. For hook and loop, simply align and press the disc onto the pad; no adhesive cleaning is typically needed, just ensure the hook and loop surfaces are clean.
- Storage: Store sandpaper discs flat to prevent them from curling, which can make adhesion difficult.
- Handling: Avoid touching the adhesive side of PSA discs with your fingers, as oils can reduce the adhesive's effectiveness.
By following these steps, you can easily replace the sandpaper on your disc sander and get back to your woodworking or metalworking projects.
