How to tune a fountain pen at home

Short answer

You can tune a fountain pen at home by cleaning it, aligning the tines, improving ink flow, and smoothing the nib using very light pressure and the right materials (like Micro-Mesh). Done carefully, this can transform a scratchy or inconsistent pen into a smooth, reliable writer.

What does “tuning” mean?

Tuning a fountain pen is the process of adjusting the nib so it writes:

• Smoothly in all directions (no scratchiness)
• Consistently (no skipping or hard starts)
• With the right ink flow (not too dry or too wet)

Most new pens, even good ones, benefit from small adjustments, even if it's only to match your writing preferences. Read why we offer tuning for new pen purchases.

Tools you’ll need

You don’t need a workshop, but using a dedicated desk space or tray helps you keep things organised.

• Clean water and cup
• Tissues, paper towel
• An ink you know well (we use Pelikan 4001 Royal Blue, it's low flow, so a good test)
• Good quality paper (we use Rhodia pads, smooth and white, shows ink colour correctly)

Optional but helpful:

• Bulb syringe for flushing
• Loupe (10x magnification is ideal) or phone camera
• Micro-abrasive sheet (eg. Micro-Mesh or 3M Tri-M-Ite)
• Brass shim (or very thin plastic)
• Clean cotton cloth for cleaning

Step-by-step: Tuning your fountain pen

1. Always clean the pen first: Many “nib problems” are just dried ink or manufacturing residue. Flush the pen with clean tap water. Repeat until water runs clear. Test your pen before moving on. We find majority of issues are fixed by flushing the grip section and nib unit with a  bulb syringe and tap water. For stubborn residue, use pen flush. 
   
   
2. Check and align the feed & tines: The obvious sign of tine misalignment is scratchiness in one direction only. First, look at the feed and check it is exactly square on the nib. Straighten the feed if needed and test if pen now writes smoothly. Next look at the nib head-on (use a loupe if possible). Check if one tine is higher than the other. Gently push the higher tine down using your fingernails (tiny movements only). We use a tissue over the top surface of the nib to protect it from scratches. Go slow and recheck the smoothness often.
   
   
3. Improve ink flow (to fix dry or skipping pens): Signs you need this include hard starts, skipping or very light, dry lines. Slide a brass shim gently between the tines to clean or "floss" the slit. If needed, slightly increase tine gap (very carefully). We do this by either pulling the "shoulders" of the nib in an outwards direction for a few seconds or "wiggling" the brass shim in the tip of the slit to create more space. Test flow after each small adjustment.
   
   
4. Smooth the nib (last step only): Only do this if the tines are aligned, ink flow is good, but the nib still feels scratchy. Use Micro-Mesh (very fine grit). Most guides tell you to write figure-8 patterns, but this can quickly create a flat foot on the bottom of the nib. So take care to use a loose wrist through each figure-8, to ensure you vary the pen angle on each pass. You're lightly polishing a round object, not grating a block of cheese. Test every few strokes.
   
   
5. Final test & clean up: Use the pen at your normal writing angle and test the various strokes. Horizontal, vertical, diagonals and some general handwriting. Expect strokes in the upward direction to be lighter than downstrokes. Use a clean cotton cloth to remove the fingermarks from the pen. We avoid using synthetic micro-fibre cloths as they can add micro scratches to the pen body.

Quick troubleshooting guide

• Scratchy in one direction → Check feed/tine position
• Skipping or hard starts → Low ink flow 
• Too wet → Tines too far apart or air getting in
• Too dry → Tines too tight, feed blocked or no ink

Who should try this (and who shouldn’t)

Good candidates include beginners with patience, with pens under ~$150, and minor writing issues only. Avoid tuning if it’s a valuable gold nib and you’re unsure, the nib is visibly damaged or you’re tempted to rush.

Pro tips from our nib tuner

• Always test on good paper first
• Make one change at a time
• Visualise the change before you do it
• Check the writing feel after every change
• Stop as soon as it feels right
• Most improvements come from alignment, not smoothing

Jen, our nib tuner, uses two sayings to guide tuning:

1. Avoid feed leftovers: It's a play on the perils of leftover food, but reminds you to avoid a left leaning feed. It causes the left tine (writer's POV) to sit closer to the page and will catch as the pen is moved left to write, which is the main direction of most handwriting.
2. Lower tine narrows line to same side: Picture the lower tine as an anchor. If the left tine is down, when moving left, the left tine drags, but right goes at normal speed, closing the slit and reducing line width.

When to get a professional tune

If your pen still isn’t right after this, it may need advanced tuning, feed adjustment or smoothing beyond what you can achieve with figure-8s. That’s where a professional tune makes a big difference. We use optical grade tools and have a wide range of micro-abrasives to use depending on whether the issue is related to the nib tipping shape or sharpness at the edge of the slit.

Final thoughts

Tuning a fountain pen is one of the fastest ways to improve your writing experience, better understand your tools and build confidence using fountain pens. Start small, go slowly, and you’ll be surprised how much better your pen can feel.

FAQs 

Can you ruin a nib by tuning or smoothing it?Yes, if you apply too much pressure on the tines or over-smooth the nib. Small, careful adjustments are safe. Learn on stainless steel nibs, and remember that gold is a lot softer.

Do all fountain pens need tuning? No, but many benefit from minor adjustments to reach their full potential. We provide this service at no extra cost for fountain pen purchases over $59.

What’s the most common fix? Aligning the feed. Most advice talks about aligning the tines, but most manufacturers make a quality nib and feed. We believe micro-misalignments are common and due to a slightly off centre feed placing unequal pressure on the tines. Straighten the feed, and often the tines will automatically align. This solves most scratchiness issues and doesn't require a loupe.

Is Micro-Mesh necessary? Only if smoothing is required. Most pens don’t need smoothing after they are properly tuned. It is however a very satisfying skill to be able to troubleshoot an irregular surface or make your own nibs ultra smooth.

How long does tuning take? Usually 5–15 minutes for basic improvements. Write some notes as you go to help guide your process. If you order a new pen from us with the nib tuning option selected, allow an extra day before despatch.
