My patio overhang has two posts that bear some of the roof weight and, from what I can tell, these look to be constructed of probably an iron pipe enclosed squarely by two lengths of 5 1/4" wide board on two sides and two lengths of 3 3/4 " wide board on the opposite sides (making a box around the pole.
The lower portion of the 3 3/4" wide boards is rotting due to its contact (and water) with the patio blue stone. I want to cut out about 2 feet of both planks of this width board and replace it with new board (and prime and paint). Unfortunately, this is an odd sized board width. Typical board widths (lets say a 1x4x6 board) has the width of 3 1/2", not 3 3/4". I have no idea where to obtain such a width board. What am I missing here? Did the original builder/carpenter cut down vertically (length-wise) a larger width board to make this odd sized 3 3/4" board?
Now what?
Thanks. Walter
