Well actually I want to make a monoblock, but where's the video of his discussion? Does he go into any details on accomplishing it?

I think I found the video. Watching it now.

Very informative video. Wish I could afford my own CNC mill, but my plan it to send my designs somewhere to have them milled. Except I'll probably buy a 3d printer to ensure they all fit together and mount correctly first.
