Hi watched your video, it had no sound, now I don't know if that was deliberate or a problem with YouTube, but you need to fix that as it's very hard to figure out what's going on without a soundtrack and maybe some music. Also, it's a very specialised area and would hold little or no interest for anyone to sit through 8.48 minutes of it, who wasn't involved in the same line of work.
You should change the link to ensure the correct video or videos come up when someone clicks on them. There is no way for anyone to know which one you want them to watch. I clicked on the link, up comes your exhaust bending video and I assume that's the one you want us to watch.
