I became infatuated with several of the filling mechanisms I saw at the Dallas pen show a few weeks ago so I decided to try my hand at a few of them. The first is a button fill pen. The ink is held in a rubber sac which is compressed with a pressure bar. To expand the pressure bar, a button at the end of the pen is pushed in hence the name "button filler".
Instead of just guessing at everything, I decided to make this pen from clear acrylic so I could see what was happening and where I would need to make changes as I went along. I made the section and it is a little different in that it cannot accept a converter or cartridge. It has a small nipple at the bottom which the rubber sac is attached using special cement. I tried making the button from several materials before deciding on titanium rod stock which I thought was going to be a nightmare but turned out to be quite pleasant to turn and notch.
Below is the completed pen, it writes just fine, holds almost twice the ink of a normal converter or ink cartridge and is just fun to use. It's a bit long at 6" when capped so I'm planning on shortening it a bit before making a few more in various colors.
This is a prototype, not meant to be a pen for sale so I spent little time polishing it.
