Building a Large Staircase and How to Layout a Stair Stringer

hey what's up everybody welcome back to the channel my name is Kyle and for today's video I wanted to make a quick one just really nice and simple how do you make a stair stringers one as a template already done and I'm gonna take you guys through how I did that how I figured out the rise of the run and you know some real simple math that'll make your life a lot easier I've already made this stringer as a template because I always like to do that and I would recommend you always to make one stringer make sure it's perfect before you go ahead and make all of it but I'm gonna show you how I did it now the first thing you need to have is the height and not only the height of your framing but you need to know the height of your finished floor so that everything can be equated to the entire formula now for me it's one ten and a half so I've talked about this before guys but the construction Master Pro is the calculator I use on site and it's really easy check this out I literally can go where it's gonna hit clear a couple times make sure there's nothing in there one hundred and ten and a half inches so that is my floor to floor height so that's my rise I'm gonna go ahead and put rise so now my calculator knows that's my height and I'm just gonna hit this stair button and boom there's my riser height seven and three-eighths of an inch so I don't you don't have to have a calculator to do that you can use simple math you can divide 110 inches by whatever you want or maybe you want 15 treads or 14 treads and you're gonna get the same calculation but for a small price tag if you're in construction and there's probably some cheap free calculator apps out there but this one is really powerful and I use it all the time and I've definitely shared it with you guys now for tread width I like to use a two by twelve always and I go ahead and give myself a nosing or an overhang usually an inch and a quarter everybody's gonna have a different tread width depending on the run that you have available for your staircase a lot of times if you're confined you might have to shrink that up to something smaller so the next thing I want to show you guys is once you have your calculations you're gonna use one of these now maybe not this one in particular but some sort of a framing rafter square we already know that our rise is seven and three-eighths of an inch if you look over here I've already got this set up but hopefully you can see that right where my framing or my to buy hits the square is seven and 3/8 of an inch so that is my riser height and if you look over here on this side right where my framing square hits my lumber is at 10 inches so what that means is I've set my square up to be 7 and 3/8 Rives 10-inch run now what I do and I've already done this one so I'm going to show you here on this other board first thing is I like to maximize my material so I'm gonna come in here and just give myself an arbitrary first riser okay this is the angle of my first step the face of my first step and you'll notice all I did was flipped around my square still on the same dimensions and it's going to give me that angle now when I rotate it back okay I'm gonna have to move this one second now when I flip it back over remember I've got that set at ten and seven and three-eighths all I'm gonna do is line up this edge at ten right where this thing comes in perpendicular don't always go off of your eye where you think it's supposed to be and move this far over if you see what just happened it looks like I'm right in line to be on a perfect perfect connection to this corner but because material is kind of rounded and weird it's always nice to just make sure that your ten inch like that is perpendicular perfect to the line that you've just made and all you're gonna do is you're gonna come in here and you're gonna make your little triangle this is what's going to get cut out for your stare and it's gonna be ten inch seven and three-eighths one thing that I want you to know is that when determining your stair layout I said you have to know all of your final dimensions because this first step if I just go ahead and cut it at 7 and three-eighths okay and I make this the bottom that's on the ground what's gonna happen is I'm gonna go ahead and put another two by twelve right here the two by twelve is gonna sit here for my first step now this rise is actually nine eight eight and seven eighths of an inch we don't want that so with that being said you have to consider your first step you have to take an inch and a half off of your seven and three eighths so if I was at seven and three-eighths and I'm gonna go - an inch and a half and I can just do this pretty easily here by doing inch and a half you have to you have to make sure that you figure that and this is the thing that I always messed up as a beginner as I would always forget to subtract my bottom and I would end up having too tall of the first step and same goes with the top remember at 1/10 and a half that's my top finished floor you have to remember that because otherwise you'll have to potentially short of a top step so we're gonna go ahead and lay this out really quickly but I'm going to show you another tip that will help you be more accurate and for stairs I think it's super important to be accurate so what I like to do is make a little tick mark right on that first tread corner and almost going to set myself a nail and then what I'm gonna do is I'm gonna go back in this calculator app another perk of having the calculator seven three eight rise that's my tread height my riser ten inch run gives me a diagonal of 12 and seven sixteenths here's the cool thing I'm gonna come here I'm gonna click my tape measure over that nail and I'm gonna come down the side and I'm gonna mark 12 and 7/16 then I'm gonna go ahead and I'm going to add another 12 and 7/16 24 and 7/8 and I think you're probably gonna understand what I'm doing here but I'm gonna go down this whole thing adding 12 at 7:16 37 516 so for the sake of time we're not going to do all of them but what that allows me to do is to ensure that I never get off by really anything because materials are no good wood is just inconsistent look at that I just made my mark and it is dying right here so this is basically a quick check to make sure that I don't ever get off because it's very easy to either grow your dimensions by being off just 1/16 or 1/32 every time but this is a nice visual check to make sure that my tread riser and my run are always dying to the exact same spot I just thought that would be a good little tip to remember that is how you mark out your stairs so I'm gonna do that whole thing and then we'll show you how I cut it out and I'll give you some tips and tricks on making sure that you stay nice and accurate when you're putting your stringers now if you're curious about this you might have seen it you might have not but this is a Martinez tool titanium framing square every one that is made it comes with your name on it you have to request this mark is a buddy of mine he actually gave this to me so quite blessed but what I like about it unlike the stair gauges that you see unlike an empire which are awesome I mean they're cheap there are seven ten dollars they latch on to the outside and sometimes it's hard to see exactly what you're doing because they get in the way with these knobs here in the middle you have clear access to the outside of your square but also they're oversized so the the thickness of this helps with any of the inconsistencies of lumber as lumber seems to get worse every year all these rounded edges you get sometimes some some really bad stuff like this those little stair gauges they don't work because they're not big enough these things work really well I don't make anything off of mark he is a friend of mine and this is a great tool specifically for rafters so it's amazing for rafters and someday I'll show you guys that too now that we have the entire stringer marked out this was the template that you guys saw at the very beginning of the video so I know it's good I like to go ahead and I take all of my stringers and I will square them all up to be flush on the top side the side that you are actually going to be cutting out and then I screw them together and then because I'm fortunate enough to have a boom saw this thing will cut through the entire stack I'll show you how this works I think it's pretty slick I don't have any eye protection on me don't blast me too bad in the comments I'll make sure that I got my safety squeeze on but I recommend always wearing as much safety protection as you can obviously guys so as you can definitely see what this allows you to do is it's gonna allow you to make perfect templates that are all exactly the same I used to just go ahead and cut one out then I take my pencil and I'd come and I'd scribe along it but what happens is especially if you're doing a lot of these things can get off and then it becomes exponentially different from one to the other so hopefully that makes sense I'm gonna go ahead and get all these cut out and then I'll show you guys maybe installing them we'll go from there so now what I'm doing is putting my top riser on I'll put the riser in the mill and the riser in the bottom and then I'll go ahead and stand this up these will come back off and get glued but this is just temporary I find it easier instead of having a bunch of stringers standing up there like a spaghetti noodles I kind of get them together and then put it in place the paint go north ah alright so there is the starting shape of the stairs they really probably aren't that strong as a single piece but when you put it all together I always like to try to do minimally 16 inches on center some guys would maybe just do one in the middle or you can do what they call a strong back and you can match out one two by twelve and then put a solid two by twelve up to the edge the only problem with that that I have in a shop is that it kind of gives you a lot of place to collect dust and dirt when you've got kind of those cracks so this is open it'll be nice and easy to keep it nice and clean alright it's finally time to install all the treads and risers and I remember I just put these here to make sure everything stayed nice and spaced but and I did the top one that way I can glue and fasten the bottom one first and then I'll take this off and now I'll work my way up installing the riser first then the tray oops I almost forgot Greg here you got yours on yep my Isis Tunes you not only weren't bluetooth with your phone or whatever you could take phone calls sounds pretty good if they're noise canceling I think they decrease the decibels by 22 decibels so much OSHA certified as hearing protection on the job site so they're really good they're pretty comfortable they don't bother me I'll wear them all day I just got back from lunch that's why I didn't have men and the biggest thing is I know this when I go home maybe you notice this - Greg my ears don't ring when I'm laying in bed I feel fine yeah all right I just took my router here and router this out for this pipe I really wish the pipe wasn't there but it is what it is and looks like I could probably make that work but it's a little bit tight so let's go ahead and route our out just a little bit more all right now the fun trade Hopi doesn't ever want to change that pipe like a pile of sawdust for me yeah but really I just wanted to add some exists or some extra holding power here on the stringers they're all screwed in from the backside but you know this is just gonna help obviously as time goes on you don't want things moving around too much I'm actually gonna go on this side that way they're kind of visible to the eye now thing to note is it wouldn't fit in here because this is an odd space but my 16 inch on I don't have a problem getting in here and shooting my shot is a it's always a good feeling when you're putting that last part to the job and you know that you're finally there and complete nice smooth transition especially when I suck it down if you look here this is what I love about G arcades when they go in they don't make a big mess out of the material they just basically tear it and make a nice clean recess so they just really look finished even though this is a even though that's a framing screw they look really nice and that is the stairs you could add some structure underneath however I don't think I'm gonna do that in any permanent fashion I'm gonna go ahead and I've got one scrap piece of to buy that out I'll go ahead and I'll fasten underneath this outside and really the only reason I'm doing that is because I think the client is going to bill like a little utility room underneath so I'll let him do that and I'm just gonna put the support there just for added grace because this is a pretty tall staircase once it glues all the blue hardens it's going to be really nice and salad but yeah handrail don't worry customers doing that as well around this whole mezzanine that's all we got here for the staircase hopefully it helped you guys if you got any questions drop them down below in the comments make sure if this was helpful to you if you guys enjoyed the content hit that subscribe button

that one and clean ha that's clean
