Dip pens generally provide more contrast than a ballpoint,
and allows for variable line thickness depending on pressure and stroke. If you
have never used a dip pen for any type of sketching, you should give it a try.
Although there are many types of pens like this available, I
decided to design and manufacture my own around an existing nib. The design
incorporates a standard available component (the nib) and the re-implementation
of waste material (copper tubing) in its assembly. The nib was manufactured in
England and purchased locally in South Africa from a stationary supplier. The
bodies of the pens are cut from copper tubing from the refrigeration industry (presumably).
The copper is then polished
to luster, which also removes any edge burrs. The design is straight forward - the nib fits into the copper tube, and gets
bonded in place with a suitable thermoplastic adhesive. A test prototype has been in use for several
months and proves successful. The copper will tarnish, which can be brought back
to luster if desired, with a suitable brass/copper polishing compound.
