pearson 26 autopilot
I have seen two particularly nice installations where a autopilot bracket had to extend out from the face of the seat. The first was a beautifully fabricated aluminum bracket that a fellow had made himself from a piece of 3/16" aluminum angle and plate. In plan it was a triangle with the socket at the point of the triangle and the base of the triangle against the seat face. There was a trianglar ''knee''at the centerline of the socket that was welded to the top and vertical face of the bracket as well as the socket.
The other really neat installation that I have seen was one that looked like a little teak gate leg table. Again the top was approximately triangular and had a hole for the bushing for the autopilot to pass through. The bushing was actually installed in the gateleg and passed up through the top locking it in place. The whole assembly proturded less than 3/4" into the cockpit when folded.
