The ladder is now built. I had to use it a few times before I posted my success story…
It will not be in a fixed location due to space limitations. I plan on storing it along the ceiling under the loft.
I used #2 Pine 1×4. (3/4″ x 3 3/4) for the sides and steps. Under each step there is an additional 1 x 2 to provide additional strength. Each screw is 2 5/8″ in length into pre-drilled holes to help prevent splitting boards.
The leg bottoms and steps are at 14 degree angles so climbing up will always have a flat surfaces. Here are closer shots of the unions:
