Dollar 717i Disassembly?

[duna]

I was writing with one of the amazing Dollars demonstrators I obtained from FPN's user smeden (no affiliation), when I noticed that the internal end of the transparent barrel (the one closer to the blind cap) and the external part of the piston group are threaded.

Suddenly I realized that if they are threaded, maybe such a thread may be unscrewed, I tried with my bare hands (without forcing too much) in both directions, but without any apparent success (I'm unwilling to force it to the limit, to avoid breaking the barrel or something) out of a slightly threaded imprint on my fingers.

It's possible to disassemble a Dollar? I was almost sure after noticing the thread, but it appears to be almost glued in place. It's a pity because it would made a great starting point for some DIY project (borrowing the working parts and trying to manifacture a barrel, cap, section etc):smooth, cheap, nice and piston filler...

I speculate, of course, my Dollar being some miles away at the moment-- I believe that the threads the blind cap cling to are a continuation of the same threaded portion which holds the filler in place. If the material used to hold them together isn't too serious about its duty (shellac, which is clearly NOT involved in the demonstrator, or perhaps some kind of silicone), it should be possible to turn the whole thing out of the barrel. I was working on an Alpha brand pen with a similar set up which wasn't very firmly glued in, and whose threads agreed with those of a Vacumatic wrench....

Yes, they can be dismantled. And it does just twist out (Same direction you turn the blind cap to remove). It can be a challenge to get it loose the first time. Don't grib it too tightly or the thin plastic will crack.

Yup - it does come apart. The threads are in the normal lefty loosey righty tighty orientation. They are rather hard to unscrew on some pens though. I have one that comes apart quite easily and several that are quite hard to disassemble.

 

Immersing the pen in hot water (but not too hot or for too long) might do the trick.

thank you guys for your precious knowledge on this pen. I'll try (and I'll let you know what's left of the pens and the fingers alike :ltcapd: ).
