I've acquired from Adams Wood the four rice posts I plan to use for the construction of my daughter's king size bed. The posts are made in three sections, the bottom square is no problem for the rails. But the middle section is round decorated with carvings -- all very beautiful but creating a nightmare for me trying to figure out how I will make mortise joints in the middle section to accept the head board.
You can get an idea of the dimensions of the post from the supplier but in the main, the base section is 3 1/2 inches square and the round section varies.
