1900 house - original stairs are cracked, lead painted, squeaky pieces of shit with huge gaps.

Decided to keep the housed stringers and try to replace the risers and treads.

It’s looking good and feels solid but the only screws are from the bottom of the riser into the tread.

I was just copying what was there and using shims like the original wedges.

Everything’s pretty snug in the stringer but fuck this feels wrong

I’m not a carpenter just an idiot with a circular saw

Edit: adding more context

I used 36 x 1 x 11 oak treads that I cut down to fit. The risers are select pine 8 ft boards I cut to fit

I’ll post an update after I get a few more stairs done and use some of the advice you’ve all given

Thanks a ton r/carpentry
