Carpentry and Woodworking - stair rebuild

I have pretty much the same problem as Drentals who has a post in this forum.Didn't want to hijack his thread so am posting my own.I plan to rebuild carpted u shaped stairs with center landing.Using oak treads(11") and poplar risers(8").Closed on both sides with skirt boards and drywall.I've done stairs before but never to such an exacting degree.I'm assuming the skirt boards would simply be an inverse of the stringers.My problem and question is for tips on how to cut treads and risers at proper length for tight fit without wasting either,and for hiding or correcting minor errors.ANY help is appreciated. Thanks

Your skirt board is a solid board slid down behind your wall stringer, which should be about 2" from the wall. You will have to trim the bottom and top at the ends to allow the board to extend below the mouth of where your tread and riser meet. Then your treads and risers are installed, with the edge covering the skirt as you go up. Be sure to take measurements at the front and back of each step so your cut will leave minimal gaps. Determine with a small square which side is out of square and adjust your cut accordingly on each side.

Chandler thanks for your response.I feel a wee bit smarter now.Measuring at front and back of each step should help quite a bit for tight fit.It may be somewhat a waste but I've been thinking of cutting the treads and risers in osb first to check to check the fit.

Never a waste to get a job done right! But by the third tread, you will be a pro and may opt to "go for it". Good luck with the install!!
