What are the smoothest castors/wheels going?
I want to make a kind of stool that I can screw something to and wheel around but the wheels need to be buttery smooth and move in any direction, so as well as buttery wheels I need buttery swivels for them. I presume a tripod design seems the most stable.
If you go the inline skate wheels route as Tester says, you’ll do worse than popping some half decent skate bearings in there. Some Bones Reds are a good budget choice. For wheels, go for something under 80a (this is the urethane hardness - ‘durometer’).
