Well today was the first day I got to work on the plane and just the plane. No more building work tables, no more assembling equipment, just me and the airplane. My day actually got cut kind of short due to me needing to help out some family members, but it's cool, it was over 100°F in the shop today.
I finished match drilling the hinges and everything to the HS rear spar. For the center hinge, I primed the bearing's flange, then match drilled and *gasp* riveted! Yep, I squeezed my first six rivets on the airplane today.
I completed match drilling and assembling the HS rear spar and left it clecoed together, then started on the HS front spar. I clecoed HS-710 and HS-714 angles to the front spar channels and match drilled the holes, and stopped for the day while shaping the edges of the two angles. I shaped the angles on the belt sander and finished the edges with files and sandpaper - MUCH quicker than doing the whole thing with a file. =D

We finished tapering and rounding the ends of the two pieces of angle. Then we dressed the edges with files and finally 400 grit sand paper.
We found the center of the angles (based on the pre-drilled hole pattern, NOT the ends which we rounded) and marked the bend lines then mounted the angles in the vise, making sure they were true with a square, and bent them. The plans say to bend them with a mallet, but I just used my hands and it was much easier. I slightly over-bent one side of HS-714, so I did use the mallet to shallow the angle back out.
I spent the day working on the HS front spar. I finished trimming, notching, surface finishing, and bending the two HS-702 spar channels. I made my first dimples in the airplane using the pneumatic squeezer on the spar channels. I didn't have Section 5 from the preview plans with me, so I spent a while playing with my micro-stop countersink cage so I don't ruin HS-710 and HS-714 by countersinking too deep. I think about 30 more minutes of getting familiar with it and I'll be ready
