Quote:10 tooth pulley is not very efficient. The smallest I would consider is 16 tooth, but I prefer 24.. then I 3d print larger pulleys like 180 or 240.I wish I had access to a 3d printer to make that possible. The one business I know of locally that does 3d printing has their office completely closed to the public for Covid.
Quote:How many turns does the wheel rotate?
3 and a half turns for full rudder movement from one side to the other.
Quote:You can use just about any windshield wiper motor. They typically have 2 windings, one is 60rpm the other about 90. This you can reduce down to get 15-30 rpm you need to turn the wheel.Would this be a good alternative? https://www.robotshop.com/en/12v-16rpm-h...ction.html
