Make sure that the bottom of the round tread
nailer isn't going to be in the way of the stair stringer. As you can
see, the stair stringers have construction adhesive on them and this
rounded stair tread is ready to be nailed in place.
Before you glue or nail the rounded stair tread in place, make sure that
you have positioned it in place, to make sure that your plywood nailers
are going to work fine.
It's always a good idea to double check every stage of your stair
building process, before completely nailing everything off.
