|The front derailleur was less complicated than the rear one, but it still had multiple pieces to complete the assembly.|
|The center piece was made of a
laminated plastic sheet. The top side was left uncut, until all the
other sides were made. I drilled three holes, and I cut and opened
the slit. Then, I trimmed the outline to
the final shape.
Finally, the top side was cut with a hobby knife as shown in Photo 8-1b.
||The chain guide was made with plastic
sheet as shown. Again, the slit was cut open first, and then, the
outline was cut. Instead of following the final outline, I left a margin around
it and carefully filed to the final shape.
||The slider rod was made of metal
pipe and pipe spring. It didn't have to be functional, so all the
pieces were glued together.
This is the right side view of the finished derailleur.
||This is the left view of the derailleur. White parts were all made with plastic sheet. Chrome part is plated brass rod, and gray part is a very fine pipe spring.|
This is the left rear quarter view.
Next part is the seat, and I'll explain how to make a shell part like it by the heat-and-smash method.
