The spring-loaded arm for the glueServo was finished by installing the parts outlined in the previous sketches.  Washers to go around the aluminum bar were added even though they were not in the sketches.
Parts for the tensioning arm

The lock nuts were positioned to keep the large fender washers and bearing loose and able to move freely as well as line the bearing up with the saw blade.  The saw blade has not been screwed down to the servo yet.

The tensioning arm was loaded with small rubber bands.

Hinge and elastics

The protoshield was soldered with most of the necessary components.  A speaker was also added since once was available and already owned.  Components were merely placed according to convenience then wired accordingly.  Instead of a plug-in debugging box with potentiometers and a button these components were soldered to the board.

The power supply had the end cut away and the wires were stripped.  The ends were tested with a meter and polarity marks were made on the ferrite filter.  The ends were trimmed and soldered to the protoshield.

To do:

  • Replace wooden stand with longer version and mount to pie tin
  • [Physically] Install Arduino
  • Test + Debug
  • Revise documentation
