This is a jig that I made to align the stair treads during the assembly process. The steel frame intentionally has a lot of room for adjustment to allow for irregularities in the floor and the walls and any variation in all the parts involved. These treads are screwed into the steel plate from below. See the steel plates here and to see the steel frame going in go here.
Stairs fill the stairwell
The entrance looked large without the stairs. Now its filled up. I didn’t skimp on the scale of the stairs. I didn’t want to compromise on the ease of getting up and down. These stairs will get a lot of use.
Something like a spiral staircase just wouldn’t be useful for frequent trips up and down. A “fireman’s pole” might be helpful for trips down though.
There is still plenty of work involved in attaching the hand rail posts and fabricating a new hand rail for the stairs but, for now, I rather like it just like this.
