Very nice, the cabinet looks great. The finish on the clock, great. How is it at time keeping, I have purchased the 0.5 mm spring for the 2.5" main barrel, I wanted to use a fusee chain, however the curve given in the book is not suitable for the chain because when I cut on the larger diameter it only leaves a flat not a groove, I want to use a chain as I have cut the barrel 13 TPI pitch.
