I'll do my best to explain what you'll need to buy and how to get it all together, but unfortunately I did not take pictures of the process. It shouldn't be hard to figure out by looking at the pictures I attached, if you have any questions please ask in the comments. I got the basic idea from other more detailed posts on this page, and just tweaked it with things I came across. Hope this helps someone!
