TWSBI Classic Disassembly and Reassembly Demonstration

One of the great things about TWSBI pens is that they’re so easy to disassemble and maintain. This is true with all their pens, especially the TWSBI Classic that was recently released. I have already done a full review here, you can see how it compares to the TWSBI 580 and TWSBI Mini here, as well as my video showing how to fill it here, and a writing sample of it here. To add to the TWSBI Classic video archive, I wanted to show you how to take it apart and put it back together.

In this video, I cover:

  • Disassembly overview (0:51)
  • Removing cap insert (1:39)
  • Disassembling the cap (2:55)
  • Removing the nib/grip (4:37)
  • Disassembling the body (8:10)
  • Toothpick trick (9:07)
  • Explanation of piston (11:16)
  • Re-assemble piston (12:38) 
  • Threading the piston mechanism (16:45)
  • Final steps (18:12) 

This is exactly the kind of video I fully expect to generate some questions, so feel free to ask away in the comments below.

    Brian, you need to get a small screw-holding screwdriver 🙂

    • Haha…clearly! Or I just won’t ever take the screw out ever again 😉

    I love that you had no ink on your hands from the start through 2:54 and then 2:55, BLAMMO, ink everywhere. Never trust a fountain pen user that doesn’t have ink on their hands. Now I’ll go back to watching the video. You guys put a TWSBI Mini into the post for me just today and eventually I’ll have to clean it. Thanks for the step-by-step instructions.

    • Haha, yeah. Well, when showing a disassembly vid I’m not getting my hands inky. But then I needed to mess around with Tyler’s pen and of course, ink on fingers. Then I realized I needed to reshoot one part of the video, and there you have it. Normally I do everything kind of in one run, but in this case, it was a little chopped up. C’est la vie! I figured it was more important to have the info in the vid (with inky fingers) than to leave it out. I’m glad this’ll be able to help you out, Maggie!

    Simple ways to reinsert the cap screw…

    If the screw is not magnetic, (or even if it is magnetic, a piece of
    two-sided scotch tape stuck over the flat end of the screw driver will
    also hold the screw in place as you start to put it back together.

    Another way to reinsert the screw in the cap (if you do take it out) is to use a screw driver with a longer metal shaft that can be magnetized (just putting a small magnet on the shaft will magnetize the shaft). Place the screw on the end of the screw driver shaft (the magnetized shaft holds the screw in place). Then, carefully, insert the screw driver (with the screw “attached”) into the cap and, by gently feeling around, set the screw in place and twist away. Of course this will only work if the screw itself is metal and “magnetic”). Or, as suggested below by TJ, you can buy a magnetic screw driver.

    Brian, how is it that your "fancy suit" doesn't have any blue in it? I like the purple, it's striking, and suits you, pardon the pun, but with your "slight" obsession with blue, I was surprised. What's the deal?

    Brian, I saw the video few weeks ago, and I decided to buy this pen.

    Today arrives to Chile, and I had a very big surprise. The pen is very well constructed, smooth and nice writting sensation.

    Thanks!!

    I know this is an old video, but I am so glad you made it! I just got the nerve to take apart my Classic and this was so handy in figuring out how to get the piston filler completely out and then put it back together properly. Now the piston just glides so smoothly that I don’t have to struggle to fill my pen anymore! Thank you so much!
