One of my favorite conversations was dealing with a smaller time builder and he didn't understand what I meant when I was talking about winders.
Me: Hi Rob, you can only have a single 90 degree turn with winders. You have a double set turning 180 degrees.
Rob: Well, the designer said that these plans were already accepted by another jurisdiction, so why is it OK for them, but not for you.
Me: I'm not sure Rob, but I can give you the code section if you want.
Rob: No, that's fine. If you are saying it's in the code, it must be in there. By the way, what is a winder?
Me: You know how the steps turn as they go down in your house right now? That is a winder. The designer put a second set in the design here though, so if someone were to fall at the stop step, you are falling like 3'.
Rob: Oh, that's what a winder is. I hate them. I will talk to the designer and get them to redesign the stairs to remove all the winders. I don't want them in my houses at all.
