Step 4: Bending the aluminum

Here's how I've bended the aluminum. I have the luck to still be a student (Industrial Product design and now Industrial Engineering).
This means I could use some precise machinery and so on. But the aluminum is very easy to bend so you could bend it around a wooden 90° frame with a hammer for example. 

I've bended both frames in one time, so that the inner diameter is nicely inside the bigger inside diameter.
