How To Shorten an Aluminum Awning Window

This is a how-to video I made that may help someone extend their construction budget. I had a unique problem, the ruff opening were shorter than the windows, but I didn't want to spend the $200 per window. I search the web and could not find advice or information to help resolve my issue. So the idea came to me to modify the window to fit the opening. I figured I had nothing to loose but a lot to gain. It worked. So, because CZcams had been a source of help and information for me in the past, because there was no information about my issue, I decide to post the video. Maybe it can help someone else or be a source to another creative idea.
