Brief Description:  Upper Engine Mount Updrill

Updrilled the upper engine mounts to their final AN-3/AN-4 sized bolt fittings. The upper engine mount sits just on the cockpit side of the firewall and performs three major functions:

1. Attaches the upper forward longeron to the firewall.
2. Serves as the primary support for the upper engine mount attach points.
3. Is the hinge point for the forward-opening canopy.

The mount is made of welded plate steel and is quite sturdy. Once I have all 4 mounts (2 upper, 2 lower) updrilled and fit into place, I'll remove them for painting before final installation.
