Started fitting the AN837-4D elbow - 4 hours

 Time to get started on the brake lines. One item that I didn’t do yet was fully open the pilot hole for the brake line fitting in the F-772 forward bottom skin. The reason why is I want to make absolute certain that hole is centered in the opening in the weldment.

This is a very time-consuming process but my previous dry fitting showed that the holes are just a tad off. To start, I made sure the hole was centered. Then I started opening up the hole. Of course, I can’t use a unibit without damaging the weldment. So lots of work and lots! of time with the Dremel.
