Finish a staircase - PEM BB dimensional.straw.staircase

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the straw badge in Dimensional Lumber Woodworking.

Going from a rough staircase to a finished one is a bit complicated and requires a fair level of woodworking skill.  There are a number of ways to trim out a staircase.  Let's take a staircase from rough to finished!

 
 

Here's a gentleman showing us one way to do it:


Minimum requirements:
  - Convert a rough staircase to a nicely finished one
  - Wood treads and risers
  - At least 5 steps
  - Including skirt board or wide trim against walls
  - Use real wood, not an engineered product
  - Tight gaps in all joints.  Clearly smaller gaps than the thickness of a credit card.

Provide proof of the following as pictures or video (<2 min):
  - The rough staircase
  - The wood you're going to install
  - Midway through the install
  - Finished stairs showing tight joints
