Love keeps Turning

1. Cut and engrave all heart layers and spacer circles.
• Laser cut the solid heart, the open (outline) heart, and all circular spacers.
• The dotted circles on the solid heart are alignment guides showing where the spacer circles will eventually be glued.

2.  Do not glue the circles yet.

• Leave all spacer circles loose until the gears are cut and test-fitted.

3. Cut the gears.

   • Cut the gears from metal (aluminum was used for this example), though wood or other suitable metals may also be used.

   • Ensure all gear teeth are clean and free of burrs so they rotate smoothly.

4. Test-fit and align the gears.

   • Place the gears over the alignment circles so each gear properly meshes with the adjacent gear.

   • Adjust positioning until the gears rotate freely and the motion transfers correctly from one gear to the next.

5.  Glue the spacer circles.

   • Once gear placement and rotation are confirmed, glue the spacer circles to the solid heart and then to the open heart layer.

   • Do not allow glue to contact the gears. The gears must remain free-spinning.

6.  Final check.

   • After the glue has cured, spin the gears to confirm smooth, continuous motion.
