Still working on the HS front spar - 2.5 hours

Started in on working upon the HS front spar. I drew Center lines on the front spars to ensure that everything was straight. I marked out the lines for the doublers and then clamped the doublers to the spars and match drilled the holes #30.

I cleco'd the angles to the spar and completed match drilling all the holes. The holes turned out perfect with the exception of a couple holes just inboard of the bend line (the middle of the group of three closest to the bend line). The middle hole of the group is just a fraction of an inch out of line as the adjacent holes since I was not perfectly plum with my had drill. Very minor and not an issue but it's the only negative.... I'm really pleased with how it's all turned out.  


I continued on with the HS-701/714 and bent them to 6 degrees. I found that my cheap protractor was a bit to cheap and unreliable. So I drafted up a 6 degree guide on autoCAD and printed it out and used that. The bends all turned out great. I then trimmed the excess of the ends and used the scotchbrite wheels to clean them up.
