Reply to comment by unhappyoptimist_ in Replacing stair tread by unhappyoptimist_

If you wanted to, you could keep the broken tread as well. Carefully remove the whole tread, clamp the pieces together, drill some 1/4" holes in perpendicular to break. Unclamp, add glue, clamp, tap in some dowels and allow to dry. Just cut/sand down the dowels and reinstall. It will never look perfect, but it will probably look better than any other attempt to replace that tread.

Good luck!

did not suggest a repair as that is a little more difficult to do well, however In fact a repair to the broken tread is almost certainly quite easy. There is no need or significant benefit to adding dowels and they add a significant degree of complexity, if the tread has broken as cleanly as it looks a simple glue joint is likely to hold for another 100 years or more, though you will have to make sure the tread makes full contact with the stringers and upright.

Good call. I like to overengineer things. Plus then you can point to the dowels and say "look, that's where I fixed it" and people will be impressed.

That is certainly one way of doing things, though in my opinion the people who get impressed are those who don’t understand what is involved so I probably don’t want to impress them.

When I do a repair my aim is usually to completely hide that anything has been done. So in this case a simple glue joint is likely sufficient, however if I wanted belt and braces I would add a floating tenon or 2 (still invisible), but of course after the joint has set you can easily drill a few holes for dowels, that they are redundant for the joint strength though of course doesn’t matter as you can use wood for the dowels that doesn’t completely match the stair tread for added emphasis ;) .

As to over engineering it is certainly better than having items fail, so I usually ere on the side of “too much is only just enough”
