FINAL ASSEMBLY (CONT.)
Finishing touches
Now, just a couple of things for the final assembly. Turn the shafts all fully counter-clockwise, then put
on the knob and rotate until the indicator line is aligned with the dot on the enclosure that shows the
zero point. Affix the knobs to each of the potentiometer shafts as shown in the diagram below.
Using a small flat-head screwdriver (no more than 0.1” / 2.5mm in diameter), tighten the set screw until
it presses against the shaft of the potentiometer and holds the knob in place.
Don’t over-tighten or you could damage the set screw. However, if it’s not tight enough then the knob
will be prone to falling off or losing its alignment with the markings on the enclosure.
Last, just close the panel on the back using the four screws. Before that, though, grab a permanent
marker and write your name and the completion date on the inside of the back panel. This is an
accomplishment!
