Have i Put the Center of Rotation for the Rotor to much to the left? I wanted to make a pressured Air engine but i think i fucked Up the Pins will fall Out on the right emd and If i make them longe i think they would bind Up because of torsion. Also the Idea with the ridges on the Rotor and the Blades was to decrease friction of the surfaces will this Help or just cause more Problems? submitted by /u/Swimming-Driver5069 [link] [comments]
