Today was a great day! The last two fuel tanks (six total) were leak-checked and loaded in the back of the truck for the trip to the UPS Store. And I was back in the shop working on the rudder.

Sorry for the completely poor manners. I'm crashing this thread to try to contact Tony Spicer offlist. Had your email years ago and can't seem to find it. Please contact me at jeremy@kilocharlie.us

Re: Flight controls
Glen,
Next time you're messing around with the brake, take a strip of aluminum a couple inches wide. stick it in the brake and make a bend right down the middle at as sharp an angle as the brake will bend it. Tape it on to the clamping piece on top of the brake. That effectively puts a bigger radius on the sharp edge. Now clamp the piece you want to bend and bend away. You'll see it has a nice radius. Need a bigger radius? Use two pieces. A good brake will allow the clamping piece to be adjusted for setback.

Re: Flight controls
Tony or Dan,
I guess what I'm trying to figure out is how Dan sets up his brake to bend the aluminum and achieve the proper bend radius. If you look at the brakes most sheet metal shops use, the upper blade has a sharp angle. This produces a small radius bend. This is fine for bending steel, but won't work for aluminum.

Re: Flight controls
Tony,
A few thoughts jump out here. Certainly Dan does great work. It reminds of what Chip Foose does on Overhaulin; he makes or modifies the parts if they are not readily available. The results speak for themselves. Have fun building.

Re: Flight controls
Glen,
Dan uses bending brakes, press brakes, male dies, female dies, setbacks and published minimum bend radii for 6061T6. And a very large dose of talent.

Re: Flight controls
Tony,
I have used brakes to make duct work, with galvanized steel for years. I know I can't bend aluminum the same way. If you don't give aluminum bends enough radius, they will crack. Bending steel is much easier than bending aluminum, so be careful when using a Sheet Metal shop's brake. How does Dan get the proper bend radius when he made his control surfaces?

A big box arrived yesterday. Flight controls and tank parts at last! Dan tried local sheet metal shops for the flight controls. They told him not possible with the accuracy he wanted. So he did it himself. And they are beautiful!
The trim tab is temporarily attached to the left elevator with four small tabs. Just above the tab are the trim tab spars. If you've ever built an RV trim tab you will love this.
Will get the current set of tanks finished, then jump on the flight controls. All the ribs have already been formed.
