It resumed until I ran into some wood I couldn't move, namely this post. I made a note of where to notch this board and carried it to the chopsaw. I veerrrryyy carefully cut away most of the notch... and broke out the waste piece. Ta-da!
Then sadness. I couldn't fit it in place, under the post.
Gravdigr, this is the
half board we spoke of. It was dark, I was tired, good. night.
