Flyrgreen and Dana make good points about not mentioning "airplane." But I wouldn't mention anything about a vehicle, either. Say it's for a garden hose reel stand, or and plant stand on your patio, or a garden tool rack...something that has to look good, but wouldn't scare their insurance goomers. There are many ways to bend the tube you mentioned, but like mtgunner inferred, we can't really give you applicable advice without knowing the radius and angle of the bends you need to make. 6061-O bends a lot easier than -T6, so I'm not sure if a rig set up for 5052-O will handle it...at least you're not trying to bend 2024, that stuff is stiff!
