You are correct that would be far better than the ones I did and if I had known of it I could have done that? but perhaps it may have gotten too complicated and impractical for me? using 3x2inch steel studs there is not a lot of room to operate battery drills I had my knuckles skinned many times, however that old saying applies there, the job is not done right unless you have bled yourself twice, thinking on my feet here I can now see with a change of materials using welded angle iron building the stairs in a workshop may be the way to go. this is definitely a better design than the ones I have.
