Belt sanders are versatile tools that can be effectively used for sharpening lathe tools. They offer a quick and efficient method to maintain sharp edges on various lathe tools, including chisels, gouges, and scrapers. When used correctly, a belt sander can provide consistent results, saving time and effort in the sharpening process. This guide will explore the key aspects of using a belt sander for sharpening lathe tools, including model selection, grit sizes, techniques, and maintenance tips.
What Are the Best Belt Sander Models for Sharpening Lathe Tools?
When selecting a belt sander for sharpening lathe tools, consider the following specifications:
- Belt Width: A 2″ wide belt is generally preferred over a 1″ belt due to its stability and even grinding capability.
- Motor Power: Look for a belt sander with a robust motor, typically in the range of 3-5 amps for home shop use.
- Speed: Aim for a belt speed of around 5000 surface feet per minute (sfm) or higher for efficient metalworking.
Some recommended models include:
- Record Power Belt & Disc Sander
- Wilton 1 x 42 Belt Sander (though a 2″ belt version would be more ideal)
- Grizzly G1015 Combination Sander
How Do Different Grit Sizes Impact Lathe Tool Sharpening?
Grit sizes play a crucial role in the sharpening process. Here’s a breakdown of commonly used grits:
| Grit Range | Purpose |
|---|---|
| 80-100 | Rough shaping and initial grinding |
| 120-150 | Refining the edge and removing minor imperfections |
| 220-320 | Final polishing and honing |
Using a progression from coarse to fine grits ensures a sharp edge and extends the longevity of your lathe tools.
What Are the Best Techniques for Using a Belt Sander on Lathe Tools?
To achieve optimal results when sharpening lathe tools with a belt sander:
- Use a jig or fixture to maintain the correct sharpening angle (typically between 20-40 degrees).
