I'm contemplating building a foldable set of stairs to gain access to the rafters in my garage and looking for ideas.
Ceiling height is 8', give or take an inch, and I'm thinking of making it about 10' long. My idea is to have it fold in the middle, so it will fold flat against the ceiling when not needed. Construction material I'm considering is basic 2x4 material with the steps set in dadoes on each side.
Is there a formula that will tell me what angle to put the dadoes so the steps are level?
Suggestions, criticisms, are both welcome.
