Hacking A Rollerball?


Recommended Posts

I'm trying to accumulate some nicer (but not expensive) bodies to hold my Pilot G-2 refills. Unfortunately, the first one came today and it doesn't quite fit, so I'm trying to determine if it can be hacked or if I need to send it back. I thought I'd ask for insight from those more experienced than I. :)

The pen is an OHTO Words. It takes a refill that's almost identical to the G-2 refill, but the "almost" is causing an issue. There's something about the tip that isn't quite fitting through the hole, and I don't know if maybe I can drill it out? When I put the original refill (that the pen came with) in, I have to kind of push once it gets almost in, to get it to go all the way in and "seat." It's a little hard to explain; it feels a bit like when something hydraulic moves. So I'm not sure if there's some intentional mechanism in there that I'll mess up if I try to drill it out.


Another potential approach would be to hack the refill, but I don't know if that's doable. You can see in this picture that the original refill has kind of a "collar" where the tip is attached to the "cartridge" area. The G-2 has that, but it also has a second "tier" of collar. I can't tell for sure if the diameter of the tip is the problem or if that extra collar is the problem, or both.


Here you can see the two refills side-by-side. Also, you can see where the original refill inserts to without resistance as compared to when it's all the way in.


Any suggestions? Anyone done this before?





Be blessed!

The G2 write nicely. You forgot to check the OHTO to compare the refills. They are not the same. Select a pen that uses the same size and shape cartridge. Or . . . . . . get a fountain pen.

Any suggestions for how to find out what pens those are? I ordered the one I ordered because I found the cartridge for that pen on a list of cartridges that are (supposedly) the same size and shape as the G-2. (And I guess they kind of are. I think I could put the OHTO cartridge in my G-2 if I wanted to.)

Be blessed!

Hi there! I've been buying a few Chinese made Rollerball pens, and have had no problem fitting them with G2,Energel, or Jinhao refills. Lately I've been using a green/black Baoer 388 with an Jinhao refill. It's a nice combination.

Just about any pen they offer as a fountain pen also comes as a rollerball.

There are some nice ones to be found.

Waterman Hemisphere is drop in for a G-2 refill. Mine is black with gold trim.

I received a Parker 75 RB today. The refill moved in and out of the tip by about 3-4 mm. I cut a small cylinder from a pencil eraser and wedged it into the non-writing end of the refill and it now fits perfectly, without any wobble. It doesn't sound like the same problem that you are having but I thought that I would chip in anyway.

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
