Preparation and Safety Guidelines

Tools Needed
  • Belt sander
  • Drill press
  • Sandpaper (various grits)
  • Micromesh
  • Drill bit (3mm)
  • Wooden blank
  • Resin
  • Rag
Safety Guidelines
  • Resin is a potent irritant. Always work in a well-ventilated area and wear gloves, eye protection, and a dust mask.
  • Resin can exothermically react (release heat) during curing. Avoid using excessive amounts in one mold and monitor for excessive heat buildup.
  • Dispose of resin and its waste properly according to local regulations. Never pour resin down the drain or into the trash without proper handling.

Step-by-Step Instructions

  1. Rough Shaping

    • Shape the resin blank into a teardrop using a belt sander. Aim for a rough teardrop shape, focusing on getting it as close to your desired shape as possible.

  2. Fine Shaping and Sanding

    • Fine-tune the pendant's shape using a drill press and sandpaper of various grits. Start with a coarser grit and gradually move to finer grits for a smooth finish.
    • Wrap a rag around the top of the pendant to protect it from damage during the sanding process.

Tips

  • If you don't have a belt sander, you can use a handheld belt sander upside down, securing the trigger with a zip tie.
  • If you don't have a drill press, you can use a cordless drill, holding it steadily and firmly.
  • Don't overtighten the pendant in the drill press; a firm squeeze is sufficient.
  • Keep one hand on the opposite side of the sandpaper to help steady it while sanding.

Common Mistakes to Avoid

1. Air Bubbles

Reason: Improper mixing or pouring technique can trap air bubbles in the resin, resulting in an imperfect finish.
Solution: Slowly pour the resin, and gently swirl or use a toothpick to release trapped air bubbles before curing.

2. Uneven Surface

Reason: Insufficient leveling or an uneven mold can lead to an uneven, bumpy surface on the cured pendant.
Solution: Use a level surface and carefully pour the resin to ensure even distribution, then gently tilt the mold to distribute the resin.

3. Dusty or Contaminated Resin

Reason: Dust particles or other contaminants settling on the resin before it cures will leave visible imperfections.
Solution: Work in a clean, dust-free environment and seal the finished piece with a sealant to remove any impurities.

FAQs

How do I avoid bubbles in my resin pendant?
Bubbles are a common problem! Ensure your resin and hardener are thoroughly mixed (gentle stirring is key, avoid vigorous shaking). Then, gently heat your mixed resin in a warm water bath for a few minutes to reduce viscosity. Once poured, you can use a toothpick or heat gun (carefully!) to pop any surface bubbles.
What kind of resin should I use for pendants?
For pendants, a high-quality, crystal-clear epoxy resin is recommended. Look for resins specifically designed for jewelry making; these often have a lower viscosity and better clarity than other types. Always follow the manufacturer's instructions regarding mixing ratios and curing times.
