Yes Abbas, the log shown in the photos is green. It’s a good idea to put a thin platter on your saw table if you can before you start cutting otherwise you will have clean up the table afterward.
One of the nice things about this jig is that it is easy to store since it is flat, or alternatively not store it at all and just use another board next time. It is a good idea to have the edge against the fence jointed so it runs true through the cut.
