John Harrison Wooden Clock Build

YouTube Series.

John Harrison's wooden regulator clock of 1728 was the culmination of his wooden clocks that started in 1713. The 1728 regulator clock was accurate to 1 sec per month, far more accurate than any other clock of the day. It was a simply amazing feat for someone born in humble circumstances in rural Lincolnshire. So far as I know there are just the 4 clocks in the Science museum and 1 in Leeds museum that are the Harrison's work. Martin Burgess has made several superb accurate copies. There was one other made based I believe on the Leeds clock. Very little information is available in detailed drawings and only a handful of replicas have been made. My effort is based on what information I managed to get from photos and from getting the trains to fit the frame. I was not originally intending to make a video of my efforts, but with lockdown, I have even more time available. The commencement of the project was 24 months ago and further progress was limited due to illness. I am now well on the way to finishing the internal workings and hope to have a running clock in 2 or 3 of months. I obtained my oak veneers from British Hardwoods Marketing@britishhardwoods.co.uk the boxwood, lignum vitae and the oak for the frames were all bought from eBay. I did not draw the clock upon CAD before starting and worked by trial and error in a traditional way and remade several parts as I proceeded. I may well do detailed drawings when the clock is finished. However, it is my interpretation and not a copy of Harrison's clock as I didn't have one to measure and copy. It is quite difficult to make everything fit accurately doing it the way I have.
