Step 1: Lay your framing square flat on top
of the lumber you have chosen to use for your stringer as shown
in picture above. You will be working from your right to
your left. Position the framing square between 8 and 12
inches away from the right edge of the lumber.
Step 2: Line up the individual step or
tread measurement on the framing square with the edge of lumber.
Step 3: Do the same on opposite side for
Step 4: In our example above and most of
the examples through out the book, we’ll be using 7 1/2 inch
risers and 10 inch treads. Don't make any marks on lumber
until you have positioned your framing square correctly.
Step 9: Before you can mark the next tread
and riser you will need to line the tread measurement mark on
framing square up with the riser mark on lumber. Then you
must re-position the framing square as shown in step four.
Once this is done, mark lumber for your second tread and riser.
By now you should have something resembling
the picture above.
Step 23: In this illustration you notice
an inch and a half thick ledger and get a better idea why you
subtracted an inch and a half from your last tread.
Landing Wall Method
Step 11: As you can clearly see in the
illustration above, the line representing the top of the landing
joist, lines up perfectly with the top of the framed landing.
Sometimes a picture can be worth a million words and if you
didn't understand what you were doing earlier, when laying out
your stringer, hopefully by now you do.
