How to build a spiral stair case

[Music] [Music] [Music] Hey [Music] [Music] [Music] [Music] this video will be going over the design and building of a spiral staircase here are all the materials there's a couple of completed steps here the area where it's going is in this ship container which is standing on end so the result will be a staircase about 40 feet tall with four landings and then access to the roof I started out here this is four and a half inch schedule 40 steel pipe bolted right to the ground the treads I started out with four by 10 sheets of diamond plate 3/16 I had them cut into nine pieces so there's no waste so that ended up with a 40 inch by 9 inch tread then I had a local steel yard Bend do two 90-degree bends in them and then I ended up with a shape that was nine inches on one side and 13 on the other there's an example that this is the tube that fits over the four-and-a-half inch schedule 40 I used this big square tubing because I couldn't find another pipe that would fit over in that big of a size if you were doing a smaller staircase you could probably get away with some smaller material like this this is probably four and a half inch pipe and four I don't know what this is but they fit but I wanted something pretty substantial for that so these are all gonna get welded together and you know it's got to be strong it's going on 40 feet so these steps I did here's the math how to do this so every floor was a little different so we have a hundred two inches 108 110 and then 154 but that's coming out on the ceiling so it's that may turn into a ladder so to figure out how to make this so it's actually gonna get gonna go together and you're not gonna make yourself crazy you want about an eight inch tall step so I divided so that ends up being about fourteen steps per landing so then you take a hundred two inches divided by fourteen steps and then you need 7.2 inches of rise per step on the first floor the second floor comes to 7.7 and there it comes to that so I had the steel yard cut all the all of these [Music] the right heights it was a lot easier to have them do it because they have the proper tool that cuts that easy and turns out perfectly square every time like I could do it with my plasma cutter but it just it would take longer and it's hard to cut through something like that and get it perfect every time [Music] [Music] I'm gonna kind of end this how-to video at this stage right now the first section of snares are done I am ready to pretty much start the second section but it's all gonna be about the same so everything here is welded it's ready for paint and then the banister has to go on for the banister I just use the plumbing pipe the plastic stuff for underground well lines I have some over here that works pretty good because it's easy to bend just screw it on it's sturdy it's never cold when you grab it it's cheap so I'll just do the same over here so I'll do another video probably less of a how-to and more of just the time-lapse showing the rest of it being built but there's really going to get this next next thing up because right now you can't get from the second-story to the roof again which is kind of annoying because the go outside is kind of a long walk so that's kind of high priority then the fourth floor where there's nothing even up there yet just the roof of the container that needs to be done too and then at the very end it's going to turn into a ladder so you can get on to the top of the tower but then I'm going to do a bunch of stuff up there too [Music]
