To make your iPad support, you will need only one thing: a strip of brass or steel measuring 2in x 12 in x .025 inches thick. I buy this at my local art supply or hobby store. You can also buy it on Amazon here
Once you have obtained the brass strip, use scissors to cut it down into a 2inx6in rectangle, as shown. Steel scissors will cut through brass quite easily, but you must go slow -- if you have them, you can use tin snips instead. In this picture, I am demonstrating with a piece of scrap metal.NOTE:
If you have purchased a USB Typewriter from my store, the stand is provided already -- there is no need to make one, so you can skip this step.
