Answer
Secure the part, use a small backing block or folded sheet, and keep pressure light.
Why it happens
Small pieces need controlled backing and light pressure so edges and details are not damaged.
Recommended grit
Use the grit required by the material, then step finer gradually.
Wet or dry
Dry or wet depending on material and finish stage.
Success check
The part is evenly sanded without rounded details or gouged edges.
What to do
- Secure the small part safely.
- Use a small block, stick, or folded sheet for control.
- Sand lightly with the correct grit for the material.
- Step finer only after scratches are even.
Avoid: Do not hold small parts in a way that puts fingers near sharp edges or moving tools.
