I don’t usually sand with 60 grit, but I went through disc after disk getting the last of the bark off the sides and getting it rough sanded. I’ve left a tiny bit of the inner layer of bark here and there because it is quite difficult to get all of it off. I will apply a bit of finish over a section at some point to see how it looks before deciding if I need to go the extra mile. Because of the sharp angle on most of the edge, it will not be particularly visible day to day. Here is a picture of the bottom of the slab with the edge sanded:
I also marked off the line for the crosscut for the waterfall leg. Following Mr.Jinx’s suggestion, I marked the midpoint of each end, drew a line the length of the board, and then used that mid-line to place the perpendicular line for the crosscut.
