Things You'll Need:
- Measuring tape
- String
- Wood
- Saw
- Carpenter square
- Pencil
-
Step 1
Determine how long you need the stringer to be. To do this,take a piece of string. Attach one end to the deck, and then put the other end on the ground where you want the bottom of the stairs to be.
-
Step 2
Use the length of string to measure how long your stringer needs to be. Lay the string across the piece of wood that you'll be using as your stringer. Use a pencil to make a mark on the board where the string ends. Now you can cut the board so that it will be the appropriate length.
-
Step 3
Use a carpenter square to measure the angle that you need to cut on the ends of the stringer. To do this, take your string back outside and reconnect it to the same spots that you connected it earlier. Put the carpenter square against the edge of the deck, and note the numbers that the string crosses. Do this for both ends of the string.
-
Step 4
Take your carpenter square to the wood that will be your stringer. Put the carpenter square on the end of the wood ,and draw a line connecting the numbers that the string crossed. This is the angle that you need to cut the wood at in order for it to be flush with the deck's edge.
-
Step 5
Do the same for the other end of the wood, but this time use the numbers that you got from the place where the string met the ground.
-
Step 6
Cut the wood along the pencil lines that you have drawn. Now you have stringers for your deck.
