    Default Is it possible to seal Kaweco Perkeo's barrel?

    Kaweco Perkeo's barrel has a hole in the end.

    Is there a way I can fill the hole in order to convert it into an eyedropper?

    Like a drop of wax in the hole, varnish or epoxy?

    Thanks...

    I am faced with a similar dilemma and my solution is crazy glue mixed with baking soda. https://youtu.be/-RIBRMf-AWI

    I would use 2 part epoxy. If you mix it with anything then try talcum powder

    Thanks Chrissy. You mean after I mix it, I add some talcum powder?

    Yes after mixing both parts together. I meant for you to use it to bulk it up instead of using bicarbonate of soda. When I sealed the cap ends in my Sonnet I used 2 part epoxy mixed with chalk and black pigment because the cap disc is black. It makes the glue thicker than if you try to use it on it's own as it might all dribble through the hole or make a mess. Aim for a thickish paste that it firm enough so it stays in position while you carefully fill the hole. Then smooth it out so it looks neat. You might need something down inside the barrel behind the hole while you're filling in order to prevent it from going through.

    Thanks for the clarification. My apolgies for being thick headed... What is the difference between using bicarbonate vs talcum power?
    A bit confused here, sorry...

    I don't know for sure about the effects with epoxy but baking soda is a catalyst when used with cyanoacrylate (Crazy Glue). It makes the glue almost instantly turn into a solid.

    Restorers who use epoxies also use chalk. I think talc is as similar to chalk as you might have in your home. It's just a bulking agent to make the paste. Sodium bicarbonate is a bit more chemical and I don't know what it will do in the epoxy.
    If you just use epoxy you won't like the result and it will also be coating the inside of the barrel where it dribbles in.

    This is an image from how I sealed the edges around the top of a Parker Sonnet cap by making a black epoxy paste:

    Why not just use a black epoxy? It's out there. I don't see any point in adding anything to it to make it thicker. If you need to make something thicker, use Cabosil, which is used in the plastics industry as a thickening agent/reinforcing agent.

    For uses similar to this, I've used black golf club shafting epoxy. It's a two-part epoxy that cures overnight and contains tiny pellets for space-filling. It resists water reasonably well and is pretty strong because it is used to build golf clubs.

    Ron, that was Chrissy's example.
    I was just asking to block the tine hole in the barrel.
    One of the pens is indeed black (and on it's way) and the other is pale blue.

    To be honest, I'm more into functionality, than aesthetics
    As long as I can turn the pen into an eyedropper, I don't care how it looks like..

    Depends on how thick your epoxy is. Mine is quite liquid.

    Mine is a Lepage, quite pasty and thick. Still it can dribble, I guess..

    I still wouldn't use baking soda as a filler. It reacts with any acids that may present. Talc is reasonably inert.

    As my mixture was quite thick, I didn't use a filler. Maybe I should've have. 18 hours into curing and it's still a bit sticky...

    Sorry, I've only just read this.

    Can you get Miliput there? That's my weapon of choice for this sort of job (and many others if truth be told).
