Stair stringer layout

You have bean tasked to build a flight of stairs. What is your first move? [[Cut 7" risers|Cut 7" risers]] [[Measure total rise|Measure total rise]] [[Determine Unit rise| Determine unit rise]]

Not the right choice. [[Go back|Start]]

Yes that is correct . You successfully measured the total rise of this flight of stairs to be 2300mm. The home owner has requested a unit rise of 175mm with a run of 280mm. Choose your next move! [[Room #4|start cutting stringers at 175mm x 280mm]] [[Determine unite rise| Room #5]]

You need to know the total rise before you can calculate the unit rise. [[Go back|Start]]

That's not right. First you need to determine the unit rise. Divide the total rise by the desired rise to find the number of risers. 2300/175=13.142 You have 13 rises. if it was 13.5 you should round up to 14 rises. Now divide the total rise by the number of risers to find the unit rise. 2300/13=176.9 [[Go back and measure the total rise.|Measure total rise]]

That's right. First you need to determine the unit rise.

Now divide the total rise by the number of risers to find the unit rise. 2300/13=176.9 Now you can start the layout of your stringers. What latout tools should you use? [[Framing square, stair gages, Sharp pencil| Room #6]] [[Tape measure and a pencil| room #7 tape and pencil]] [[Make a pitch block using the unit rise and run then use that as a template| Room #8]]

You have layed out one stringer. You will be using 40mm thick treads and 12mm risers. What adjustments will you make on this stringer? [[No adjustments|Room no adjustments]] [[Cut the thinkness of the tread off the bottem and the thickness of the riser off the back of the stringer.|Room10]]

Think again you need to be very accurate with stair layout.

Yes that is correct . You successfully measured the total rise of this flight of stairs to be 2300mm. The home owner has requested a unit rise of 175mm with a run of 280mm. Choose your next move! [[start cutting stringers at 175mm x 280mm|start cutting stringers at 175mm x 280mm]] [[Determine unite rise| Room #5]]

Yes that works though using a framing square with stair gages is more common. [[move on| Room #6]]

[[Try again| Room #6]]

That's correct. You can proceed to cut out your stair stringer. Use the first stringer to trace out the others. [[Finish|finish]]

Nice work! Now you can calculate stair stringers.
