Assembly Instructions
(Photos below are provided to help follow the process.)
Start by assembling the wooden base with the gears.
Attach the side walls.
Install the launch hook mounts, followed by the launch hook itself.
Once everything is fixed, install the two pillars between the walls.
Add the first beam for the spoon arm.
Install the spoon and secure it using the second beam.
Finally, place the percussion bar on top of the pillars.
Attach an elastic band to each pillar and position the main part of the elastic underneath the spoon.
On the photos, some holes or areas may appear missing. Always refer to the 3D models, as the images were taken using prototype parts rather than the final versions in order to avoid wasting material.
