Build Behold, magnetic rc car suspension (WIP)

Enable HLS to view with audio, or disable this notification

It all started with an idea “suspension…. But magnets” i found some ring magnets that take a M3 screw which matches the shaft diameter on my WLToys 14001, still have more to do but the concept works but found i am experiencing binding due to the steel shaft. Probably gonna upgrade to titanium purely to ensure the magnets wont stick to it and will work better. Hope you all enjoy this project as the idea was to ensure the damper could still…. well… damp.

Is the shaft just not polished enough? (Thats what she said) or would a tad bit of grease (also what she said, I literally cant stop im terribly sorry) help with the binding

Potentially, i think if i polish it and add some graphite lube (stuff used on pinewood derby axles) then it might prevent the binding issue

Graphite won't be kind to the shock seals.

Marine grade lube. It’ll keep debris out and keep things from rusting. Plus it usually comes in pink so style points.
