Can someone please help me out? I am working on the second floor stairs and have them glued and ready to install into the BH. When I hold the railings, there is a space between the staircase opening and the railings themselves. I think, but am not sure, that one railing piece goes in that opening. However, what about the "posts"? How do you build them, on an inside corner or outside corner? I see that there are caps that get installed later, but I just can't figure out how to create that "square" that the cap sits on. Thanks.
