Gravitate Solar Marble Machine Kit ASSEMBLY STEPS All the laser cut parts are labeled and marked per panel. It's now the simple process of find, prepare, and assemble! Panel 3 has your linkage base (A}. Locate the small curve (B), small arm (C), and 3 x large curves (D). Use the screwdriver to remove any sticking cutouts. Assemble the pieces to the linkage base as shown. Make sure the larger of the two holes of the small arm (C) is used to attach it to the base (2x 4" screw, 1x 2" screw).
Gravitate Solar Marble Machine Kit ASSEMBLY STEPS From panel 3, get Triangle #1 (H) and Triangle #2 (I), and attach to the linkage base as shown. Install Triangle #1 (H) on the bottom (1x 3/8). To ensure smooth operation, adjust the arms by scraping & smoothing the edges shown, using a sharp knife or sandpaper. Do this when removing them from the panel steps 1.6 and | L7. "\ These 4 edges Se raping should resulting 45 degree edges that are about 1mm in width.
Gravitate Solar Marble Machine Kit ASSEMBLY STEPS Because the top screw of the “large lifter assembly” enters from the back side, make sure the screw ends flush with front of large lifter (O). If it extends past. it will interfere with the moving parts. #2 threaded § Use the #2 screw and washer to pin the triangles and large arm to any of the 4 holes of the plastic GMW motor connector wheel.
Gravitate Solar Marble Machine Kit ASSEMBLY STEPS From panel 4, remove motor mount (5) and rock it into position on the either side of the GM3 motor. Use some white glue to secure the tabs into the slots. Side view: Secure the motor to the motor mount with 2 x #4 TFS (thread-forming screws). These have a heavier thread than the other screws. From panel 4 remove the small tower {T), and from panel 2 the marble catch (U), and large tower (V).
Gravitate Solar Marble Machine Kit ASSEMBLY STEPS From panel 4, find and attach bottom track (W) as shown, using white glue at each tab connection. Start installation at the middle tabs, working out to the ends. From panel 2 remove and attach the middle track (X) as shown, again using white glue to secure all of the tab connections.
Gravitate Solar Marble Machine Kit ASSEMBLY STEPS From panel 4, remove the 2 x large receivers {Y) and 2 x small receivers (Z). Slot these all into the top of the Large tower [V) as shown. Do not use any white glue until the end of the next step as these receivers need be wiggled to help insert the top track. From panel 3, slot the top track {A2) into the receiver finger slots. When in place, use your white glue in these slots to hold everything in place. Attach the top track (A2) as shown.
Gravitate Marble Machine Kit DESIGNING YOUR OWN Hey! Do you enjoy the Gravitate and want to design your own version of the linkage? We built ours using David Rector's free linkage mechanism designer software found here: Although we have several CAD packages, we found his software to be extremely useful with a number of different options te create dynamic linkage systems with ease.
Gravitate Marble Machine Kit TROUBLESHOOTING If your Marble Machine isn't fully functional, check this troubleshooting list. Linkage jams when the arms are attempting to pass the marble try this: Use a knife or other sharp edge to shave down the inside of the large lifter arms and the outside of the small lifter arms. See page 5, below step 2.4.
