Just a FYI: when putting together the curved staircase on the Dura Craft 505 Farmhouse, make sure you dry fit the tread below the riser you have just glued in...so that what happened in this picture to me, doesn't happen to you...i.e. the curve of the riser does not match the curve of the tread. If you dry fit the tread in just after you have glued and taped in the riser, you still have time to manipulate the curve of the riser to match the tread. The directions, of course, don't tell you this.
