February 28, 2020 Update: This week I finished putting together an educational video about the physics of ricochets and spent quite a bit of time working on my CNC wood router project.   I had already welded up most of the structural frame, and this week I focussed on the mechanical part of the X-axis linear drive system, which is now pretty much complete.  The next step will be to build a supporting base or housing that will facilitate attachment of the necessary electronics, after which I will be able to start installing the electronic part of the control system.  As I am working on  the first batch of muzzleloaders for ARCO LLC, I'm also recording some video footage of most of the production operations, so I should be able to put together a video about that process eventually as well.  I still have several armor testing videos in my upload queue, so I expect I will upload another one of them this weekend.
