Magnetic Dowels For Modular Terrain

When I first started planning my modular track for micro RC cars I was going to affix terrain to each module directly so each module was set. I really wanted to have the terrain as modular but I hadn’t come up with a way of doing that other than wood dowels which I didn’t think was robust.

In presenting the first video of the completed modules on a forum one user had a suggestion…rare earth magnets. That was the inspiration I needed. I was concerned that rare earth magnets still wouldn’t quite work through the module’s plywood unless the were very strong and a few small test magnets proved that. My ‘Design For Six Sigma’ ideation kicked in and I Pughed in my brain (in joke for my work colleagues). Hybridising dowels and magnets was the way to go.

Here is a quick sketch of the intent of the system.
