HI all,
I have a couple of questions about redoing our interior stairs.
The house is 100 years old and the existing treads and risers are quite worn and some of the tread nosing has been broken off. The risers and treads are 3/4" pine boards. I have no problem replacing these, will use 1 inch oak for the treads and most likely 3/4' poplar for the risers. Will paint the risers and stain the treads to match the hardwood floors.
The stairs are about 40" wide with two stringers made of 2 by 12 (true
2 inches thick and 12 inches wide) and one middle stringer made of 3/4 inch pine.My concern is the span and the middle stringer; I would like to replace the middle stringer with a thicker one as the stairs are a little wobbly.
First is replacing the center stringer overkill? Or should I replace this with a good piece of 2by lumber
The treads are on the narrow side (about 8 inches) I read in an old construction book (circ 1940) that treads should not extend more than 1
3/4 inches beyond the riser. So to widen the steps a little I wanted to have a 1 3/4 inch overhang on each tread. Is that too much for a 1 inch oak tread?I tried to find out stringer spacing requirements on the web but no luck, only thing I found is a rule of thumb of 32 inch span between stringers. Any suggestions?
Thanks, Dave M
