3.1 Drilling, shaping, and lathe use for bead production

Here’s a TESDA-aligned, hands-on module for drilling, shaping, and lathe use in agarwood bead production, ready for training manuals, learner guides, or UTPRAS documentation.


🔨 Drilling, Shaping, and Lathe Use for Agarwood Bead Production

1. Objective

Trainees will learn to:

  • Drill precise holes for bead stringing
  • Shape beads uniformly for jewelry applications
  • Use lathes safely for efficient bead production
  • Maintain resin integrity and aroma during mechanical processes

2. Tools and Equipment

Tool / EquipmentPurpose
Hand drills / pin viseDrill small, precise holes in beads
Drill bits (0.8–2.0 mm)Suitable for bead size and cord thickness
Mini lathe / rotary toolShape and smooth beads efficiently
Sanding attachmentsRemove rough edges and refine surfaces
Files (needle, round, flat)Fine-tuning and shaping beads
Calipers / templatesEnsure consistent bead dimensions
Workbench or lathe standStable base for safe operation
PPE (goggles, dust mask, gloves)Protect eyes, lungs, and hands

3. Safety Guidelines

  • Always wear PPE (goggles, dust mask, gloves)
  • Secure beads in a lathe chuck, clamp, or jig to prevent spinning hazards
  • Check tools for sharpness and mechanical integrity before use
  • Avoid excessive speed or pressure on resin-rich beads
  • Keep workspace clean, ventilated, and free of distractions

4. Drilling Procedure

  1. Mark the hole position on the bead using pencil or awl
  2. Secure bead in a hand jig, pin vise, or lathe chuck
  3. Start drilling at slow speed, following the grain to prevent cracking
  4. Withdraw drill periodically to remove dust and resin buildup
  5. Check alignment and uniformity before moving to the next bead

Tip: Drill pilot holes for large beads to reduce stress and prevent splitting.


5. Shaping Procedure

  1. Pre-shape beads using files or sanding blocks after cutting and planing
  2. Mount beads on lathe or rotary tool for final shaping
  3. Use gradual sanding progression: coarse → medium → fine
  4. Rotate beads slowly, maintaining even pressure for symmetry
  5. Inspect bead diameter and roundness using calipers or templates

Tip: Maintain a slight oversize to allow final polishing without losing material.


6. Lathe Operation Guidelines

  • Ensure lathe is stable, securely mounted, and away from edges
  • Set appropriate RPM for bead size and resin density (slow for high-resin beads)
  • Use tool rests to guide files or sanding attachments
  • Do not force beads into high-speed rotation—resin-rich wood can crack easily
  • Always turn off lathe before adjusting clamps or bead positions

7. TESDA-Aligned Learning Outcomes

Upon completing this module, trainees should be able to:

  1. Drill accurate bead holes while preserving resin quality
  2. Shape beads to uniform dimensions using hand and power tools
  3. Operate mini lathes safely for bead shaping
  4. Apply sanding and finishing for smooth surfaces
  5. Assess bead quality for size, symmetry, and structural integrity

8. Practical Workshop Activity

  1. Trainees select conditioned agarwood blanks
  2. Drill pilot holes and finalize hole diameter for stringing
  3. Shape beads on lathe or rotary tool to achieve uniform roundness
  4. Fine-tune surfaces with files and sanding attachments
  5. Instructor evaluates drilling accuracy, symmetry, surface quality, and safety compliance

9. Quality and Aroma Considerations

  • Avoid overheating resin-rich beads; excess friction can alter aroma
  • Maintain consistent bead diameter for stringing aesthetics
  • Preserve resin-rich surfaces to maximize natural scent

If you want, I can draft the next module on finishing, polishing, and stringing beads, including TESDA-aligned assessment rubrics and practical checklists, so your UTPRAS submission will have complete end-to-end bead production coverage.

Do you want me to do that next?
