June 4, 2021 Update: Well, this week I spent practically all my discretionary time working on the root cellar.  I've got about half the trusses welded up now, and I've got the hole for the root cellar excavated and the bottom of the hole leveled as best I can.  I'm looking forward to finishing the cellar and getting back to my gunsmithing projects, but I've still got a lot of work to do on it.
Since I've got my bolt-action bullpup video ready, I think I'll upload it this weekend.
