Assemby

[Case - getting ready]

On the case, find two holes and place 2 pan head machine screws from the back. Use the screw nuts to hold both screws.

[Handle]

Put the knob(small sphere) through the handle and glue the small cap in.
Glue the square of the handle to the square hole on the small gear. (**make sure the pole of the handle is positioned at the center of the small gear.)
Place the handle at the bottom of the case. (*when placing the handle, slightly push the half-circle plate in to avoid breaking the axis of the small gear.) When test-spinning, the handle has to feel smooth and quiet. - if it’s too tight and squeaky, try sanding the handle pole where it spins and touches the case.
After making sure it spins smoothly, glue the cap to fix the handle.

[Disc]

Place the big gear on the pole so that the gear sits on the triangle of the pole. (*match the square under the gear to the triangle.)
Glue the top surface of the gear and place the disc through the pole.
After it’s dried, place the pole in the case and snap the disc between 3 fixers in the case. (*Squeeze the case if necessary)
Place the fork through the screws and align it correctly with the music you created. (*Reference your music grid from the website - note: the website grid is missing 12th, 16th, 17th, 18th notes from the fork)
Screw 2 nuts to hold the fork in place. (*Eventually the order of the screws will be: screw - case plate - nut - fork - nut.)
Enjoy your music drop!
