I've just made a start on building the English style bracket clock described by John Tyler and am wondering if anyone else has built this?
I've made a few clocks before and purchased the book more for the plans than for the instructions. In spite of the rather long and wordy nature of the book I am finding it a little difficult to follow. There is a distinct lack of dimensioned drawings, a bizarre use of metric dimensions (which are just direct conversion of imperial dimensions often given to three decimal places!) and almost complete lack of any assembly diagrams. The two fusees for example are described in the text but there are no drawings of them which is odd.
I am anticipating lots of head scratching ahead. If anyone has any detailed photographs or plans of the movement, that would be very helpful, as would any other tips or advice.
Incidentally, I am also planning to use ball races instead of pivots on this clock like I did with an English regulator I completed a few years ago. This worked very well.

Seems strange, I've just had a look at the advertising for the book and it says:-
" However the author has provided instructions which leave nothing to chance. The construction of the fusee in particular is fully covered and two appendices at the end of the book deal with the theory of the curve."

Yes, there is a long discourse on the theory of the fusee curve and the text does state the diameter at the big end and the small end of the fusee but there is no actual plan of either fusee and details of the recess for the maintaining power on the time fusee is left out. I did wonder is there were some pages missing from my book but i dont think so.
The dimensions are all very odd as well. My favourite so far is a part that calls for a 3.658mm hole. I know modern drills are accurate but that could be a challenge. Presumably that is some converted Imperial dimension...
Anyway, plates and pillars now complete, barrels and fusees next.

That looks suspiciously like 'gauge 27'
What a ridiculous way to write instructions !!

Don't worry, I'm sure +/-0.002mm will be fine
