Making John Harrison's wooden clock Part 1

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 or 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 [email protected] the boxwood, lignum vitae and the oak for the frames were all bought from Ebay. I did not draw the clock up on 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.
