July 16, 2021 Update: This week, I filmed an episode about using a lanyard or sling to improve the stability of a pistol, wrapped up some testing of my first plastic sabot design, and worked on processing pictures from last week's camping trip.  I think the concrete foundation of my root cellar should be fully set by now, so finishing the root cellar will probably be my focus for the next few weeks. Hopefully, it will only take a few weeks, and not the whole rest of my summer!  Anyway, this weekend, I think I will upload the video I made about making an improvised worm gear for my band saw.
