06/08/2018 Horizontal Stabilizer – Trimmed and Edge Deburred Ribs (2.5 Hours)

The aft flange on HS-00006 front rib need to be trimmed according to plan. I marked the line and used snip to cut with a very generous margin. After that I spent quite some time to file it down to the actual line required by the plan and round of the corners.

Then I started the deburring process – using a precision file set to debur the inner edges and relief holes, and using the bench grinder to debur the outside long edges.
