\section{Custom made keyer}
A plastic material of relatively low melting temperature is heated in
boiling water, and applied to hand, to form to shape of hand.
See Figure~\ref{fig:prepformakingkeyer}.

  \caption{Preparation for making of keyer:
           (a) pouring water from kettle; (b) putting low temp plastic into
           hot water; (c) wooden chopsticks are used to handle hot plastic;
           (d) soft plastic is tested for consistency; % 13
           (e) hand is cooled in icewater; % 27
           (f-k) soft plastic is lifted out of hot water in one quick
           movement while hand is taken out of ice bath,
           (l) finishing up with soft plastic on hand.
           If pain threshold reached, process can be repated with
           further cooling of hand. 
          }
  \label{fig:prepformakingkeyer}
\end{figure}

Next the soft heated plastic is shaped to perfectly fit the hand.
See Fig~\ref{fig:shapingformakingkeyer}.

  \caption{Shaping the soft heated plastic to perfectly fit the hand:
           (a) here a left handed keyer is in the making;
           (b-c) soft heated plastic is pressed down to form nicely
                 between the fingers, so that the keyer will conform
                 perfectly to hand shape.
           (d-h) when right hand taken away, material should feel
                 comfortable and naturally stay in position on left hand.
          }
  \label{fig:shapingformakingkeyer}
\end{figure}

Finally, excess material is trimmed away.
See Fig~\ref{fig:trimmingformakingkeyer}.

  \caption{Trimming the keyer support structure;
           when the plastic cools and hardens, it will fit perfectly to the
           hand, in the interior region of the plastic.  However, at the
           edges, the shape will be whatever was set forth by the original
           shape of the material, and will therefore need to be trimmed:
           (a-h) initial rough trimming is done while the support structure
           is worn, so that it can be trimmed to the hand shape;
           (i-l) then it is removed and rough edges are rounded of nicely.

  \caption{Finishing off a keyer:
           (a) selecting appropriate pushbutton switches;
           (b) testing for positioning of the switches;
           (c) getting the thumb switches in position is most important;
           (d) material is cut away and switches should be glued into place
               all while wearing the keyer;
           (e) keyer is interfaced to WearComp by way of a Programmable
               Interface Controller, using a circuit board designed by
               Wozniak (assembled by author) and a PIC program designed by
               Wozniak, Mann, Moncrieff, and Fung;
           (f) circuit board (in author's right hand)
               interfaces key switches to standard
               PS/2 connector (in author's left hand);
           (g) an RJ45 connector is used with 8 wires, one for each of the
               seven switches and the eighth for common;
           (h) finally the keyer can be plugged in by way of the RJ45
               connector.  The author has standardized the connections so that
               any member of the community having difficulty with their keyer
               can temporarily swap with someone else to determine whether the
               problem is in the keyer or in the conversion circuit.
