Trimming Factory stair threads with a return
We have an older house that was split into a two family previously. They butchered the stairs quite a bit to accomplish this in adding a back entrance. We are trying to restore back the original hall/stairs. We were hoping to keep all the original threads, but the first 6 were notched and cut too much such that drilling the spindle holes wouldn't be possible, so we will replace the threads. The stairs however only have a depth of 10'' inches, where most factory threads with returns seem to be 10.5 or 11.5''. If we purchased factory made treads, is there an easy way to cut the required half inch of the back side of the stair without cutting off the return? We have a compound miter saw, skilsaw, jig saw and a variety of handsaws. We could borrow a table saw if needed. Or is our only option to make the threads from scratch the correct size? Any advice appreciated! This is the first project where we've really been cursing the previous owners.
