From time to time, we'll feature posts and commentary from our sister magazine Kitplanes. If building is your thing, do yourself a favor and check out the Kitplanes blog and be sure to visit their web site.
At AirVenture 2007, I took the challenge of sampling the builder's workshopsspecifically sheet metal, composites and fabricas a clean-sheet newbie. I wanted to see if I could pick up the basic skills necessary for building, and how the instructors and Technical Counselors would do with a rookie. Thanks for their patience, expertise and clarity in explaining the basics, I was indeed able to pick up the basics. (Look for the full report in the June issue of Kitplanes magazine.)
I also developed an affinity for sheet metal work. I liked the substantial nature of working with metal, and really liked working with power tools. Okay, the hand-powered Cleco pliers were pretty cool, too.
So, when I saw the request posted by Jim Hoak on the Matronics Zenith email list, calling for builders to assist volunteers in an unusual and worthy project, the metal bug bit again. Hoak is the co-chairman of the Basic Sheet Metal Workshops at Sun 'n Fun, as well as a Zenith 601XL builder. He was also my instructor at Oshkosh.
The volunteers planned to build a Zenith 701 during the six days of Sun 'n Fun, built from a kit purchased by one of the workshop members. When the aircraft is completed (and dubbed Angel 1), it will be donated to a missionary organization. Several tool companies, including Avery, provided some metal-working tools, but the construction is being undertaken by the workshop volunteers and the folks who come to learn basic metal skillsno company participation. The plan is to build as much as possible during the show, and then complete it at the owner's home airport in Mississippi.
The 701 was well underway by the time I wandered into the air-
conditioned workshop this morning, with a good portion of the fuselage having been riveted, and with a wing and a horizontal stablizer laid out on the other tables. Under Hoak's supervision, the horizontal stab has been reworked several times until the measurements were as called out in Zenith's plana copy of which was prominent at each work station.
My participation consisted of pulling a long line of blind rivets with a pneumatic rivet puller, with the assistance of a couple of volunteers who made sure the rivets were square to the fuselage skin, and that the interior sheet metal didn't gap. After we pulled the majority of the rivets, out came the Clecoes and in went the rest of the rivets.
Good news for the occasional riveter: Properly instructed, you will remember how to do it, even after eight-plus months. And yes, it was still fun.
One of the hidden gems of this project was the piece of sheet metal to be stashed inside one of the seatsfeaturing the signatures of the volunteers who worked on the 701. Hoak anticipates that the sheet will be completely filled by the time the plane is done. Once completed, no one will see our signatures unless they cut the seat open.
But we knows it's there.
