July 2, 2021 Update: This week I was able to spend a little time working on the Ghost Eagle design.  Right now, I'm in the process of animating the CAD model to check for interference and function before I start preparing the machining drawings.  I also finished editing the video about eating wild globemallow, and filmed an episode about a simple trick for cutting pipe threads into plastic, in this case so that I could install pipe fittings in some poly drums as part of a drip irrigation system for our garden.  And I undertook an expedition to an unnamed alpine lake, which I intend to document in another photo book and slide-show video eventually, although I'm afraid I have gotten behind on editing the photos from my outdoor adventures into coherent books and videos.
