Wood Ballpoint Pen
A lathe-turned wooden ballpoint pen with a custom shape, stain finish, and beeswax seal.
// Challenges
My original two-tone wood blank split mid-prep, so I ended up mixing a yellow-red half with a grey-wood half. The shape I wanted, skinnier with a slight central bulge, also took careful work on the lathe to avoid taking off too much material.
// Skills Used
// Outcome
A finished, functional ballpoint pen with black metal hardware, a comfortable concave-bulge profile, and a smooth stain-and-beeswax finish. The mismatched wood actually became part of the character of the final piece.
Brief
This was my first MakerSpace project of the spring semester. The framing was open. Make something on the lathe. I picked a ballpoint pen because I wanted a writing tool that felt different from the basic disposable pens I had been using, and because the lathe is the right tool for turning two short blanks into a paired set.
Process
Choosing materials. Black metal hardware, picked over stainless and gold because the contrast with stained wood reads stronger. For the wood I picked a two-color blank that had a yellow-red section and a grey section meeting in a clean line.
Prep work. Cut the blank roughly in half on the band saw. Bored out the middle of each half on the drill press to fit the brass insert. One of the halves split during boring, which I should have caught earlier as a sign that the grain was running in a direction that would stress the wood. I ran a replacement half in grey wood. The pen ended up two-toned in a way I hadn’t planned, but the result is more interesting than the symmetric original would have been.
Glue and cure. Glued the wood onto the brass inserts. 24 hours to cure before any cutting.
Shaping. Mounted the blanks on the lathe and used facing tools to bring the pen toward its rough shape. The profile I wanted was skinnier than the default with a slight concave bulge in the middle. That bulge had to be carved carefully because the lathe takes off material fast. Too aggressive a cut and the whole bulge becomes a hollow.
Sanding progression. 150 grit first to remove material and smooth the gross profile. 300 grit to refine and clean up tool marks. 600 grit to bring the surface to a near-polish. Each grit took its own pass and you can feel the difference between them with your fingers.
Staining. Three coats of stain. Each coat applied with a paper towel on the lathe, spinning the wood to distribute the stain evenly. I picked three coats over the maximum ten because the wood was already on the lighter side and I wanted to keep some of the natural color.
Finishing. Steel wool with beeswax, same lathe-spin method as the stain. The wax seals the wood and gives the surface a soft, slightly warm shine. Final assembly was on the pen press, which clamps the brass internals and the wood together at the right pressure.
Skills Built
- Lathe work end to end. Mounting, facing, profiling, sanding, finishing. The whole turn-it-on-the-lathe workflow.
- Sanding progression. 150 to 300 to 600 is not arbitrary. Each grit erases the marks of the previous one. Skipping a grit shows.
- Wood finishing technique. Stain to color, beeswax to seal. Both applied while the piece is spinning so the finish is even.
- Recovering when something breaks. The split blank could have killed the project. Switching to mismatched wood turned a problem into a feature.
- Material selection. Hardware color, wood color, and grain direction all matter and all have to be picked before you start cutting.
What I would do differently
I would inspect the grain of the wood more carefully before drilling. The split in the first blank was almost certainly preventable if I had paid more attention to where the grain was running. Also a longer stain progression. Five or six coats would have deepened the color without going so dark that the grain pattern disappeared.
