Right wing main skins match drilled, left wing on the rack

We started the weekend with some motivation - pancakes! We drove to Frederick, MD to the AOPA fly-in for pancakes provided by the local EAA chapter, and some gawking.

The girls got to hop in several of the planes, including EAA's One Week Wonder. 

Later in the day, one of our neighbors, Joe, stopped by to help match-drill the right wing bottom skins.

 I completed the top skins also.

 While Joe was busy with the match-drilling, I fabricated the left wing-walk doubler and match drilled it to the inboard top skin.

 I also modified the wing stand slightly and Joe helped me hand the left wing skeleton so we could skin that wing as well.

Great to see both wings in the rack! Joe was a great help; it's been a lot of fun getting several different people involved with the build. I enjoy the solo work, but sharing it is just more fun.

Wings: 4 hrs

EAA RV Assembly Workshop

 This weekend I had the pleasure to attend EAA's RV Assembly SportAir Workshop, hosted by Chapter 524 in Frederick, MD.

 

There was some academic instruction by the excellent Jack Dueck (who's book Sheet Metal Building Basics is excellent, as are his Hints for Homebuilders videos), followed by lots of hands-on time with 2 practice projects.

EAA, with the support of Vans Aircraft and Aircraft Spruce, provided tools, prints and practice kits. The tools were adequate, as to be expected with those used by dozens of unskilled novices. Materials were exactly the type I've encountered so far, and perfect for making mistakes.

 We 16 students paired off to work on our airfoils; Pat & I made good progress, learning about countersinking, back-riveting, pop-riveting, the importance of a good air compressor, and lots of practice with the rivet gun (and how easy it is to mangle aluminum!).

 

I can see the value of a high-speed air drill over the 20V Li-Ion I've been using (weight, speed), but it was hard to get a good feel with intermittent air available.

 

EAA Chapter 524 had 3-6 volunteers circulating throughout the weekend, answering questions, offering tips & encouragement. Their help was invaluable.

 

After we completed the airfoil, Jack reviewed our work and offered suggestions to improve as we dive into our airplanes.

All in all, the workshop was worth every penny. I highly encourage anyone interested in sheet metal work or building an airplane to try to attend.

 

Thanks to EAA, Vans, Jack, @ Chapter 524!
