Learn step-by-step how to safely disassemble, clean, and reassemble your machined pen V2. Includes tips for fountain pen and inkball models, replacement parts, and maintenance best practices.
Regular cleaning is essential to keep your machined pen writing smoothly and looking its best. Whether you own a fountain pen or an inkball model, disassembling and cleaning the internal components can prevent ink clogs, corrosion, and wear. The V2 design of many machined pens, including the popular Pocket Six series, makes disassembly straightforward with the right technique. This guide covers the complete process for both fountain pen and inkball versions, along with tips for reassembly and maintenance.
Before you begin, gather a few basic supplies: a soft cloth, lukewarm water, a mild dish soap (if needed), and a bulb syringe or cleaning kit for fountain pens. For inkball pens, you may need a replacement tip or spare O-rings if the old ones are worn. Always work over a soft surface to avoid scratching the pen's finish. Let's dive into the step-by-step process.
Disassembling Your Machined Pen V2
Start by unscrewing the pen cap and setting it aside. For fountain pen models, gently unscrew the barrel from the grip section. The grip section holds the nib and feed assembly. On the V2, the grip section often unscrews from the barrel as a single unit. If you have an inkball pen, the grip section may contain the inkball tip, which can be unscrewed separately for replacement.
For fountain pens, carefully pull the nib and feed out of the grip section. They are friction-fit, so a gentle twisting motion while pulling straight out works best. Avoid using excessive force. For inkball pens, unscrew the inkball tip from the grip section. If the tip is stuck, a rubber grip pad can help. Set all parts aside in order for easy reassembly.
- Always work on a clean, soft surface to prevent scratches.
- Keep small parts like O-rings and springs in a tray so they don't roll away.
Cleaning the Components
Rinse the barrel, cap, and grip section under lukewarm running water. Use a mild soap if there is visible ink residue, but avoid harsh chemicals that could damage the finish. For fountain pen nibs and feeds, use a bulb syringe to flush water through the feed channels until the water runs clear. Alternatively, a dedicated pen cleaning solution can be used for stubborn dried ink.
For inkball pens, wipe the inkball tip with a damp cloth. If the tip is clogged, soak it in warm water for a few minutes. The replacement inkball tip can be swapped if the old one is worn. Also inspect the O-rings: if they are cracked or flattened, replace them with spare silicone rubber O-rings to ensure a good seal.

- Do not use alcohol or acetone on anodized aluminum or acrylic parts.
- Dry all parts thoroughly with a lint-free cloth before reassembly.
Reassembly and Maintenance Tips
Once all parts are dry, reassemble in reverse order. For fountain pens, insert the nib and feed back into the grip section, aligning the flat side of the feed with the notch. Push firmly until seated. Screw the grip section back onto the barrel. For inkball pens, screw the inkball tip back into the grip section, then attach the barrel.
After reassembly, test the pen by writing a few lines. If the flow is inconsistent, double-check that the nib and feed are properly seated. Regular maintenance every few months will extend the life of your pen. Consider investing in a pen case or sleeve to protect the finish when not in use. Spare parts like grip sections and O-rings are available for easy replacement.
- Lubricate threads with a tiny amount of silicone grease if they feel stiff.
- Store pens horizontally or nib-up to prevent ink from pooling.
With these steps, you can keep your machined pen V2 in top condition for years. Regular disassembly and cleaning prevent ink buildup and ensure a smooth writing experience. Explore our selection of replacement parts and accessories to keep your pen performing at its best.
