I was figuring Oskys way. Only have to remove and reinstall 1 wire. That's the proposed, once torn out, actual kicks in. And yes I figure an extra riser (2x backer) for this. I'm real confident about hanging. The hem in that area is like 2 1/4" thick.

Maybe, or you'll need to shorten the length of the top tread the depth of the backer if it's landing height. i will back away, I must have missed something. I have always had a 1/2 or 3/4 inch hanging plate across the top of the stringers. Width of the pocket/stairs and around 14" vertically. If exterior it's a piece of treated plywood. Screw the stringers into the plywood, adjusting for the plywood becoming the top rise. Thanks guys Osky

I get what both you guys are saying and thanks. My stringer wood is plenty long enough to use the backer, it is not in the above calculation is all.

My tread number was wrong too. Embarrassing how math erodes. I bucked up the square and it seems correct. Reason I did not include the backer at top, there is a landing and that will be difficult to type figure on here. I do have the plan there.
After my good saw returns home with fresh bearings, I'll get after it.
Thanks everyone.

You should have 11 steps with the first step being from upper floor to first step on stair stringers. Cut 10 steps on stringers @ 7 7/16"+ Cut 7" runs and cut treads 8 1/4" to make 70" run and wider tread. Cut the thickness of risers off the back of first step where they attach after you cut stringers so it's not wider than the rest. Cut the depth of stair tread thickness off the very bottom of last step where it meets the floor so first step isn't taller.
Buy yourself a set of stair/rafter buttons for your 2' square. They are about 7$ and priceless when laying out stairs and rafters.

When you attach the stringers measure down from the finished floor 7 7/16" plus the depth of the treads and draw a level line to attach the stringers on. It's easy to forget the tread depth on this measurement if you haven't built many stairs. Draw lay out on one stringer cut it out then trace it on the rest to speed things up and keep everything the same.
If the floor isn't 100% level hold a 6' level off the top of the finished floor and measure down at the end (71" out) on both sides of the stairs. The stringers don't make contact directly below the back of the stairs and sometimes the measurement varies 1/4" or so to where the stringers sit on the floor.

I build custom stairs for a living (trimcraftcarpentry.com) and here are my calculations. 11 risers at 7.45" and 10 treads at 7.2" (by code treads need to be 9.25" minimum with overhang). Illegal by any code and very dangerous. They will be almost 45 degrees. Going up will be marginally safe but coming down is a trip to the hospital waiting to happen, especially difficult for children and older folk. Better off to build a ladder. Sounds like stairs going down to my basement.

On deck stairs I make the outer edge of the tread 1/2 bubble above actual level. Generally stairs are a pia especially by yourself.

At the top, there is a cellar door that opens out. The only way I see to stretch the OA run is to make the first step be a riser, (stepping down) and I don't think I want to do that. I'd pay someone to have a look and advise.
I like the ladder idea lol, much easier.

A sloped ladder with large treads can be a good solution as long as it meets code and isn't a glitch in your insurance coverage for any reason.

Can you put a landing half way down and make a 90 degree turn ? The thing that makes stair confusing is that most guys don't do enough of them. If you do them regularly they become just like everything else. Listen to Bass 1 !! I build custom stairs for a living (trimcraftcarpentry.com) and here are my calculations. 11 risers at 7.45" and 10 treads at 7.2" (by code treads need to be 9.25" minimum with overhang). Illegal by any code and very dangerous. They will be almost 45 degrees.

Door opens away from the stairway, not into it. No room for even a one step landing at bottom, no headspace.
I've built quite a few, this one is challenging. 1897.
"Door opens away from the stairway, not into it." quote
More I think about it, the first top step can step down, that gains 14" run. I can cheat back the headspace at bottom "a little" but a lot of work.
Building it in my head for now until my good saw comes home. Then I go for it.
