Wall mount marble track

Create this fun and educational Rube Goldberg Wall Mount Marble Track!

To begin your project, cut plywood for the marble track back to 20" x 22" using your Dremel Ultra-Saw and smooth the edges & corners with your Dremel Multi-Max.

Next, cut your Poplar for the marble track to the following lengths and quantities: • 1 - 22" inches long • 2 - 18" • 2 - 14" • 1 - 13" (catch basin) • 2 - 9" • 1 - 6" • 3 - 4" Then, rip Masonite in 1" strips & cut to the length of the Poplar strips you just made. Measure & cut Poplar "stops" for the channel & basin ends. Next, assemble the masonite sides to the poplar base and add the poplar stop to one end as shown using wood glue.

Layout assembled channels & catch basin.

Next, you can paint/finish your plywood back, we painted ours red(optional). Then, create your pattern for the run. You can use ours as a template or make your own. Secure the channels & catch basin to the plywood. We used a combination of glue for some & nails/screws (from the back) for others. This allowed us to make adjustments for ball speed. Hang on the wall and enjoy.
