We're building a typical fiberglass model rocket kit here from a company called "Mach 1." The kit does not come with very detailed instructions, and some of the parts need post-processing to get them to fit together. So we decided to make a series of videos to help you out if you're building something similar. NOTE: The kit does come with rail buttons. It was just an "oops" in this particular kit that the rail buttons were missing. This first video shows an introduction to the kit, and you'll see my own strategy on how I'll be modifying the parts for the e-bay to put them together.
