For my 2020 Christmas gift and my 71st Birthday, I got a Carbide 3d Shapeoko CNC router. It came in the form of a kit that had to be assembled.  I stumbled through that process and after some trial & error, got it to work very nicely. This video is a series of clips showing my assembly of the system.  I made lots of mistakes - but some have expressed an interest in seeing the process.
