I designed the project as a sort of ’gateway’ project into more complex horological work, especially if you’re already comfortable with model engineering, and maybe feel like tackling something a little unusual. I’ve seen some outstanding builds of this project over the intervening years and would love to see more. So, if you’d like to build along with the series and help me make these videos, the plans for the project are available as part of the $1 tier on Patreon, find out more here: Those of you who are Patrons will notice that for this YouTube release of the series I’ve spruced up the intro card and soundtrack, and also combined a few episodes together to make it all a bit more efficient for the viewer. For those who are seeing this narrated build series for the first time, do please enjoy! Cheers. Chris. ________________________________________________________ A very special thank you to Patrons: Sinking Valley Woodworks Glenn Trewitt Christopher Warnock Guy Loughridge Charles Frodsham & Co.
