Making the 2ⁿᵈ Best Sanding Block

3-Second Blueprint (English)

1. Laminate a rigid squared oak core with fine-grain cork and neoprene in a vacuum bag press to sand flat without rounding edges.
2. High-shear double-sided tape resists lateral sanding forces, while fine-grain cork avoids crumbling unlike coarse grades.
3. Bracing fingers against the router table edge acts as a mechanical stop so a kicked-out block cannot pull your thumb into the bit.
