Curved oak staircase

I removed the carpet from the old stairs, cut off the front bullnose and installed oak plugs where the bullnose was on the stringers. I then made templates of the stairs on paper and transferred them to oak boards. I used a Festool domino to join different sizes of oak. Both sides were rounded with a router. I made the stair treads slightly larger and planed and sanded down to the exact size. I finished the stairs with a dark stained and topcoat.
