| Notes | Explores different approaches to the design of oscillators. Maximum angular swing, advantage of tangential laying out to increase port area, how setting at 90 degrees gives less than maximum swing, comparison of 90 degree and tangential geometries, marking out the guide plate for the tangential method, optimising the port area, port drilling, recapping, references |
