Homebrew PCBs

Hi Stefan (and listmembers)-

In an earlier post you said you had tried the Staedtler ink with a
plotter pen, and it had failed to plot to PCB very well. You advised
against trying this.

In spite of your experience, I would like to try this, and I am
curious what you specifically used (so I can avoid your errors, if
there are errors). The one reference on the web I could find said "You
have to use a 757 PLx CS refillable plotter point.It is a
Tungsten-carbide plotter point with a cross grove to allow for more
ink flow. The ink is fairly thick."        http://eeshop.unl.edu/pen.txt

I plan to use Staedtler 485 523 sar-9 ink (this I have now). Finding
an inexpensive grooved tungsten-carbide plotter pen is turning out to
be a challenge. The cheapest I can find is about US$64, which is too
expensive for experimenting. Anyway, what plotter pen did you use?

Can anyone suggest an inexpensive source for this kind of pen?

(I don't have a plotter but plan to make my own).
