Newel post at the top of the stairs was extremely wobbly so I took it upon myself to check it out. After taking a better look I have come to find out that not the post itself is broken, but the apparent wood piece that actually comes off the bottom that I guess goes into the floor and is screwed was broken in half. After taking out a couple of screws I was actually able to pull the newel post out easily. How can this be fixed? Can I break out the piece left in the floor, and cut the excess off the bottom of the post then maybe somehow attach a new piece to go down into the slot? Please help.
