I did end up adding some extra bracing to the top (you see this step in the video) I do admit that I was actually working out the details of this project as I went since I really didn't want to make up one first and then make one on the video. For most projects that is how I work, if I am showing you how to make something I haven't made before I end up making 2, one before filming to iron out details and one on camera to show you. For this and some of the other larger projects that just isn't practical so I do have to make changes as I film, like the extra bracing on tom.
After I put the head pins in and made some loops for the chains to later hook onto I painted my structure with some Aluminum colored spray paint. This covered up the stripes on the straw parts I had used at the top to make the curve and blended all the parts together. The paint also seems to make the structure a little firmer too.
