I finished the right wing aileron of my Bede BD-4C airplane tonight. Both ailerons and both flaps are now complete.

Here (again) are the flap and aileron for the left wing:

And here, in its debut appearance, are the flap and aileron for the right wing:

Test Fitting the Left Aileron

By Art Zemon On June 10, 2013 · Leave a Comment · In Bede BD-4C

Bonus photo: With the aileron ribs bolted to the torque tube, I did a test installation of the aileron on the left wing of my Bede BD-4C. Wonder of wonders, it fit perfectly with no side-to-side wobbling and no trouble installing the last bracket.

After confirming that the ribs were exactly the right distance [...]

Left Aileron

I am starting on the left aileron for my airplane. On the Bede BD-4C, the ailerons are operated by 10 foot long torque tubes which run from the fuselage, through the flaps, all the way to the wing tips. Here is a picture of the torque tube for the left wing with the aileron ribs [...]

Bede BD-4C Flaps

By Art Zemon On May 20, 2013 · 1 Comment · In Bede BD-4C

At long last, I am doing something large that actually looks like an airplane part! I am making the flaps for my Bede BD-4C airplane. The wings are 10 feet wide; the flaps are made of two 40 inch wide halves and the aileron is another 40 inches. To make each half of the flap, I [...]

8 Years, 600 Posts

By Art Zemon On May 19, 2013 · Leave a Comment · In Cabbages & Kings

I am bemused to realize that I started this blog a little over eight years ago and this is my 600th posting. I remember being nervous back then, wondering if I would be able to find anything to write about. I made a commitment to try it for 90 days and then decide whether to [...]

Aileron Support Brackets

By Art Zemon On May 15, 2013 · Leave a Comment · In Bede BD-4C

Having completed the mid-flap support brackets on the wings of my Bede BD-4C airplane, I continued working along the wing to the inboard aileron support bracket, which supports the outboard end of the flap and the inboard end of the aileron, and then to the outboard aileron support bracket. The outboard bracket [...]

Mid-Flap Assembly

By Art Zemon On May 6, 2013 · Leave a Comment · In Bede BD-4C

The original wing design for the Bede BD-4 used a one-piece flap, about seven feet long. The new metal wing on my Bede BD-4C airplane uses a two-piece flap, with each half being about 3.5 feet wide. The ribs at the ends of each half are tied together with a pair of 1/4 inch steel [...]

Circular Hole Cutter

By Art Zemon On May 5, 2013 · 3 Comments · In Bede BD-4C, Cabbages & Kings

I get to use some cool tools while building my Bede BD-4C airplane. The latest acquisition has been a Circular Hole Cutter. By adjusting the arm, I can cut a hole up to four inches in diameter. In these photos, I have it adjusted to cut a hole 1.5 inches in diameter.
