Why use PVC Pipe for Resin Casting?

PVC pipe offers several advantages for casting pen blanks:

Cost-effective: It’s readily available and affordable compared to specialized molds.
Easy to find: Most hardware stores carry a variety of PVC pipe sizes.
Durable and reusable: PVC pipe is strong and can be used for multiple casting projects.
Versatility: You can experiment with different sizes and lengths to create various pen blank designs.

Materials you’ll need:

PVC pipe: Choose a diameter that suits your desired pen size (typically 1/2″ or 3/4″ diameter works well).
PVC pipe caps: You’ll need two caps per blank to seal the ends of the pipe.
Resin casting kit: This includes resin, hardener, and mixing cups.
Sandpaper: For smoothing the pipe edges.
Mold release: This helps ensure the resin easily separates from the mold (optional but recommended).
Stirring sticks: For mixing the resin.
Safety gear: Gloves, eye protection, and respirator (if using a pressure pot).
Clamps (optional): To hold the pipe caps in place while the resin cures.

Step-by-Step Guide:

Prepare the PVC pipe:
- Cut the PVC pipe to your desired pen blank length (typically around 6-7 inches, allowing room for trimming).
- Sand the edges of the pipe smoothly to avoid any imperfections in the final blank.
- Clean the inside of the pipe thoroughly with rubbing alcohol or a degreaser to remove any dust or debris.
Seal the ends of the pipe:
- Apply a thin layer of mold release (if using) to the inside of the pipe caps.
- Place the caps on each end of the pipe, ensuring a snug fit. You can use clamps to hold the caps in place while the resin cures (optional).
Mix the resin:
- Follow the instructions provided with your specific resin casting kit. Typically, it involves mixing equal parts resin and hardener thoroughly for a designated time.
Pour the resin:
- Without a pressure pot: Carefully pour the mixed resin into one end of the pipe, slowly tilting the pipe to ensure the resin reaches all sides and avoids air bubbles. Fill the pipe to about 3/4 capacity, leaving space for air expansion during curing.
- With a pressure pot: Follow the specific instructions for your pressure pot model. Generally, you’ll fill the pot partially with air, place the sealed PVC pipe mold inside, and pressurize it for a set time to remove air bubbles from the resin.
Curing:
- Place the filled pipe mold on a level surface in a well-ventilated area protected from direct sunlight.
- Refer to the resin’s curing time instructions. This can typically range from several hours to a day depending on the resin type and thickness.
Demolding and finishing:
- Once fully cured, carefully remove the caps from the pipe. You can use a utility knife to gently cut through any cured resin that might have seeped past the caps.
- Use sandpaper to further smooth and refine the shape of the pen blank.
- You can now proceed with drilling the pen blank according to your pen kit specifications and finalize your unique pen creation!

Additional Tips:

Experiment with colors and additives: Explore adding pigments, dyes, or small objects like dried flowers or glitter into the resin for customized and visually captivating pen blanks.
Consider using a funnel: This can help minimize spills and ensure a cleaner pouring process.
Work in a well-ventilated area: Resin fumes can be harmful, so proper ventilation is crucial.
Always wear gloves, eye protection, and a respirator (if using a pressure pot) for safety.

By following these steps and unleashing your creativity, you can create beautiful and personalized pen blanks using readily available PVC pipe. So, grab your materials, embrace the DIY spirit, and embark on your journey to crafting unique and stunning pen designs!
