Herb, looks very professional. Thanks. I would have some leftovers as the tread would need to be trimmed to length and width. Leftovers could be used to trim the tread. Would take some time but I like it. Will run it by the CEO and see what she says. We both get a vote but her vote is bigger than mine.
Edit- Herb, looked at the photo again and need to know how to miter just a small part of the tread. Seems there would be a short miter and a long cut across the tread.
If I was doing it I would make sure the treads were 2" longer than the width of the stair.
Order an extra tread to cut the end caps from.
Mark a short 45 on the outboard end. and a new sq. end cut on the end of the tread. Cut on band saw.
Rip the bullnose off the extra tread, and whack off the width + allowance for kerf ,of the tread,cut a 45 on each end of the short rip. Make a short return for the miter on the inboard edge to return the bullnose back to the wall.
Fit the miter tight to the nose miter on the tread, glue and clamp it up.
When set, sand out any differences, and cut the tread to length to fit the stair width, and install.
I have done this with a hand saw before. It is more work and more patience and attention is required.
I hope this helps. Don't be afraid to try it.
You will have to recut the bull nose on the extra stair tread for the next rip with a router and a 1/4 round or stair bullnose bit.
