I discovered this channel when I was teaching myself to cut gears on my milling machine, just a very well done production for each step in a clock making series. It's clear this guy thinks about the production before making the pieces, and certainly spends a little time on post as well. The actual clock is cool, probably nothing I would ever build, but the machine skills I find very interesting.
