Very good answer from William there, by the way if you want to pay mine and Jims air fare William we would gladly come and peg out the pivot holes for you 
One thing I would say is if you don’t want to remove the levers etc as you might be worried about where they all go, just make plenty of notes as you disassemble them and use a digital camera too, a picture always helps when you cant figure out how things go back together. Another small tip is before taking these movements apart I mark the top of each wheel in place in the movement, that way the strike and chime should all work correctly and be in sync when the movement is back together.
