Reply to "Building a Gr4 replica"

Kristian is a very smart guy and he will be able to figure out the geometry very quickly. If someone can tell me how many Degrees of rotation the Headlight Bar is doing from closed to open I will happily provide an exact Drawing. There are several options for stroke length and that affects the length of the Arm and the time it takes for the Doors to open/close. If a 50mm stroke is used it is twice as fast to open/close as if a 100mm stroke is used. Two things are important 1) It works best if the Arm and the Actuator form an angle of 90° when the doors are half way open/closed. 2) You must construct it so that there is a possibility to adjust the position of the Actuator a few millimeters up and down in the fully closed position to compensate for wear and tear over time.
