Knex Micro Roller Coasters | How to Make a Spine

Here I show you how to make a spine on a roller coaster. I believe it was originally created by BBaller347. If you have the parts, I recommend that you use this method to further fortify your coaster to make it as close to perfect as you can. Regardless of the type you make, as in steel, inverted, wooden, etc, it will make the track extremely stable and will overall help to make your coaster more realistic.\r

FYI: this video is pretty dated, there is a slightly better method called staggering, which can be applied both to tubes and spine and helps to strengthen and smooth out bumps. Check out my video on building tubes and staggering your rods here:
