First Time Building Stairs - Everything You Need To Know (Part 2)

Well today is part two of our two-part series on  how to build a basic set of stairs if you missed   the first video i'll leave a link up here and  down in the notes below before the first test   fit measure down from the top of the finished  floor 7 and 5 16 or 185 mil which is our unit   rise and then down further the thickness of  the tread so in our case that's going to be   an inch and a half or 38 mil then draw a level  line all the way across the header as this will   mark out the location of the stair stringers  this is a 36 inch or 914 mil wide staircase so   i'm going to plan on putting three stringers in to  about an inch and a half in from the outside edges   and the other one dead center with the first  stringer held into position check that the treads   are level in general if the tread is not level  it's one of two things either it's too tall or   too short for example if the unit rise was a  little too tall the total height of the stringer   would also be too tall and the treads would tilt  back if the stringer's rise was a little too short   the overall stringer then would be short and  therefore each tread would tilt forward if   your first stringer is out of level slightly you  can always make some simple adjustments by either   raising it above or below your reference line  and that's because most if not all building codes   allow for some discrepancy or difference between  each rise so for example you can have one at seven   and five sixteenths and another one it's seven  and an eighth there are some codes that allow   up to three eighths of an inch or nine and a half  mil difference or discrepancy so you just want to   double check your local building codes before you  build your set of stairs in full disclosure i cut   my tread a little bit too tall and i'm not sure  what happened there but i could have made it work   by adjusting it like i just mentioned but i  decided to go ahead and cut a new stringer i tell   you this to simply let you know that it's okay  to have to re-cut a stair stringer practice makes   progress even for me so once you've landed on the  stringer that you like make it your pattern and   trace it out on another piece of two by material  being sure to line up the bottom of the stringer   with the edge of the new material again our  example stairs are 36 inches wide so for an   outside project or a set of garage stairs with  big thick treads like ours i personally would   feel comfortable with three treads however if this  was in a house as a finished staircase and we had   the thinner treads i would go with four stringers  just to make it extra firm again you just want   to double check with your local building code  because you've traced from a pattern be sure to   what i call eat the line meaning when you cut  don't leave the pencil line showing if you do   you'll make the stringer slightly bigger than your  pattern let's finish out this video by looking at   three different methods to attach the stringers  to the header how and when you use these three   methods really depends on your local building  codes but these three are the most common and   do provide a very secure connection first is to  use a nailer a nailer is a simple piece of lumber   that gets nailed or screwed to the stringers and  also gets attached to the studs or other framing   members under the header this of course works if  you have framing material under your header like   this but if you don't that leads us to our next  method which is to use a piece of plywood similar   to the nailer the plywood gets attached to the  stringers first but this time the plywood can get   nailed right to the stairwell header as you  can see this method doesn't require additional   framing under the header but it does require that  you have the additional room to add the plywood   the last option and the one i really like the  most is to use a standard joist hanger to hang   the stringer on the header the best way to do  this is to turn the hanger around and line it   up so that it's about an inch to 25 mil down from  the top of the stringer then make a pencil mark   where the joist flange contacts the stringer  and then use a square to lengthen that line   transfer that measurement to the other stringers  and it's okay if they're not exact the last step   is to set a circular saw blade to the depth of  the joist flange which is this measurement here   then slowly and carefully follow your lines  making the cut then all you have to do is   insert the hanger into the kerf and fasten  the stringer to the header using the nails   through the joist hanger you want to make sure  that whatever method that you're using to install   the stringers nice and plumb you don't want them  to be installed twisted as a quick side note this   is the only hanger size that i had available but  it really is ideal to use a slightly larger hanger   so that it sits lower on the stringer leaving more  material up above here in addition to fastening   the stringers to the header a 2x4 cleat that gets  notched into the lower end of the stringer works   great for stopping the stringer from kicking  out this is really important when attaching   stringers to concrete because it's very difficult  to toenail any fasteners through the stringer and   into the concrete to finish out this basic set of  stairs cut and install the inch and a half treads   using some nails or screws overhanging the sides  by around an inch and a half in the front about an   inch again this is a basic set of stairs however  if this was a finished staircase in a house   you'd want to be sure to install your risers first  and then your treads after that fully finishing   off a set of stairs is a very deep topic and one  that we're going to have to save for a future   video but as far as this video goes i hope you  feel confident enough now to build your very own   basic set of stairs thank you for watching  i'll see everybody in the next video you
