I am replacing wall to wall carpeting on inside stairs which are built with 2x treads and plywood risers. I want to replace with Southern Yellow Pine treads and 1x pine risers. What's the best method to end up with nice quiet stairs? Do the risers set on the treads or do the treads butt up against the risers? Should I use Liquid nails, wood glue or something else on the treads? Any help will be appreciated.
