I apologize for the quality of some of the pictures, but figure any picture is better than no picture. My lovely wife is a whiz with graphic software, and worked on the pictures to enhance them, otherwise they probably would have been unusable.
The mount is 1/4" ply, approx 2.13" wide by 1.85" high. The bottom of the notch is approx .4" from the bottom of the mount. The bottom of the notch is also .58" from the center of the circular cutout, and the cutout is 1" in diameter, required for airflow. The corners of the mount are slightly rounded, especially the upper right corner to clear the cowling.
I aligned the mount square with the inside and the top of the left beam (as the plane is designed for the motor to have a slight downward angle and slight right angle alignment). This ensures correct alignment for the new mount. Do not overlook this, as it's important.
The notches in the mount are sawed and filed to be a slip fit on the mounting beams, with just enough clearance to ensure no binding. I epoxied a couple of small angle braces to the front of the mount, making sure they are square and cause no binding on the mounting beams. I then centered the motor and aluminum motor mount on the 1" hole in the 1/4" ply mount, and used #4 sheet metal screws to...Continue Reading
