We're going back to pre-1800s tech in our instrument by switching the ball bearings in our motors to plain brass bearings. Hopefully if we make them just the right size they'll have "lagom" contact with the shaft, providing grounding, without being so tight that they just seize

@thardin Does that make it more sensitive to temperature differentials?

@pettter Possibly. Brass and stainless steel aren't too far from each other thermal expansion-wise, but they also aren't identical. We're going to just give it a go and see how it works. The hole might need to be broached to just the right size.. Time will tell
