Questions:
Where would someone find the rollerball pieces to interchange with the eyedropper? And, have you modified the highlighter for the task or the fountain pen?
Very interesting post, thank you.
Thanks for the information.
Used rollerball pens that are not worn heavily or clogged will be suitable - assuming they have not been tossed out yet. Most people have a few dried up rollerballs in their desks... You might notice that MANY rollerball pens have exactly the same housing and steel tips - they are produced by very large companies...then they "filter down" to very different brands of pens (often identical tips are on a $1 pen as found on a $3,000 pen!). Many roller ball refills "made" by different brands all have tips that came from the same company - most have a felt core central feed with fin regulators outside of it. Pull it out with needle-nose pliers...soak a while in rubbing alcohol or household ammonia - and refit with the highlighters felt core feed. If you tire of using a rollerball tip and would like the highlighter again...pull it off the felt core and replace with the highlighter tip. It works yet again. Provided the felt core touches the ball the roller will be fed ink. Likewise, provided the highlighter felt touches the felt core it will also be fed ink. The fountain pen nib/feed unit will also interchange with the highlighter unit upon the same pen (some retailers do carry extra highlighter tips for sale that are made by the Platinum Pen Co.).
I never have collected rollerballs with the exception of the rollerball fountain pens of the war era to approx. 1964 (even Esterbrook made one!). When a rollerball has a pure ruby bearing encased in gold with a gold wire feed - that seemed like it was far more unique and difficult to make than the ubiquitous rollerball pens that all exit similar machines and near identical factories by the millions. I try not to be a pen snob....but the fountain pen gets collected/admired, and the rollerball remains an object mostly for tinkering. Interestingly....when it comes to the length of use the fountain pen almost always outlasts and outwears the rollerball. The rollerball as a mechanism is quite dependent upon a disposable culture.
