The compilation machine is together:
-the parallel relationships between the two swinging bars in the artobolevsky machine have been attached to the circular pulleys from the second machine, maintaining the constraints that were necessary from the original machine.
-adding the arms to the circles actually helped to draw the pedal of the parabola more effectively, and as the second circle is dropped lower, it does start to draw the lower portion of the pedal.
new points have been attached to all swinging arms, which varied from the original two designs. this visually charts the swing of the two arms, drawing archs.
the machine is constucted primarily of wood, which adds much more lateral stability than the original paper machine. furthermore, it was possible to assemble the machine largely with friction fits - so it can be taken apart to accomodate any new mechanisms in further assignments.
