To be honest, I have taught myself what I know, and I don't know a lot. Youtube is a great resource, and I was just using it to figure out how I am going to build a curved railing for these stairs. These are my first spiral stairs, and I have learned a lot from the process. The toughest part is that they turn around a rectangular post, rather than a pole. Figuring out how to support them without unnecessary posts and braces was also an interesting challenge. It turns 270° total, and bracing the outer run at four points: 0°, 90°, 180° and 270°, meant I only needed to add support at 90° and 180°. The 90° is a railing post that extends up to a bridge above (which can be seen), and the 180° is a post into the ground (which you can see below). I think my first word-working project was a birdhouse. That's a fun place to start.
