I only had a short time available today, so I began making inspection windows in the two aft cover plates (under the horizontal stabilizers). This will allow me to visually inspect the elevator pushrod attach point on every preflight -- with a flashlight, instead of having to remove a bunch of screws. I will cut some plexiglas for the actual viewing windows.

I marked the two plates for 2-9/16" holes, drilled out the centers with a unibit, and used a nibbler and a file to get the first of the two holes up to full-size.
