Update report...
Finished building both left and right shelving units, as well as the upper middle shelf that spans between them.
All the MDF is cut (including biscuit slots) and currently dry-assembled for the base cabinet - I'll be gluing it up tomorrow.
Next is the facade for the TV and then some sanding, plaster work, and more sanding before dropping the pieces off to be painted. I'm hoping to go evaluate one of the possible paint shops tonight or tomorrow.
I'm currently missing a couple of clips to attach the roller for the art lift, so that's probably going to have to wait two weeks for testing. The motor itself and remote seem to be working fine as I rolled them around on the floor a bit already.
