Best oil viscosity for carts

[cyclopath]

@Lenny

any recommendations on a affordable (sub $300) viscometer?

There was a couple of low cost methods mentioned in one of our previous explorations…

And even a calibration ritual for the rotational version…

@cyclopath

feed it water, feed it milk, feed it honey, and their ilk.
spin it round. do the math. ethanol. then short path.
