Unless you have one of these:

Which gives you a rim looking like this:

You are only realy left with a file or dremel, you could also do it by drilling 4 holes where you want the corners to be and them joining with a jacksaw, still alot of effort though.

I have done a rim using a file before, was lots of effort and took a long time, 8-10hrs!

Is there a certain way to do it? it sounds stupid but i dont wanna f**k it up before i sit here for hours on end with a file?

If I were doing them I would masking tape the inside of the rim, mark out the squares sizes and spacing you want and then attack it with a dremel to take the most of the material out, use a file to get the edges all nice and flat. If you can keep the rounded corners, that will help reduce stress raisers and cause the rim to crack hole to hole on the corners.

IMHO its not really worth doing, a round hole is stronger and you wont save a huge amount of weight, remember youre cutting away aluminium which is hardly the heaviest material going - its alot of hard work for not a huge weight loss. That said any rotating weight off the wheels is a bonus, have you considered losing the weight in tyres and tubes?

That must still've taken quite a while to do though, Adam! Nowhere near as much as doing it manually obviously but still fairly time consuming.

Rear rim took 1hr30, front maybe 3hrs including making it single walled (big job on a DX32 because they are tripple box section!), so not too bad realy....

took me most of the day, not worth the while buy a rim. I used glow in the dark tape as rim tape looked cool as really hard to take pics of the rim glowing, might try reflective tape next time
