INTRODUCTION
Introduction - What is this all about? A number of years ago I became fascinated by the idea of constructing a precision timepiece from raw, stock metal, id est, 'from scratch'. At that time I knew very little about mechanical watches, and the idea began as a simple curiosity as to 'why not?', but became a goal after coming across a copy of George Daniels' book, titled "Watchmaking."THE 'TURNS'
The next step is to mill dovetails. A 3/8" 60 degree dovetail cutter was used. The cutter shown is a Whitney 903760M42 cutter. It is held in a custom made arbor, described on the page mentioned above.Unfortunately, the method of holding the work was much less than ideal, and although it worked, I would not recommend it.

The clock that is described here is an English style regulator, and is made following the method and design set forth in John Wilding's book "How to make an English Regulator Clock." I am planning to follow his design largely unchanged. However, he uses inch dimensions and British Association threads, so some changes will likely be made along TAILSTOCK DIE HOLDER Tailstock Die Holder. Cowells offers threading die holders that fit the tailstock quill of the lathe and fit standard-diameter dies (i.e., 13/16" and 1"). I have thought for some time that it could be useful to make a similar style holder to fit Bergeon 8mm diameter dies. Shown below is the Bergeon 30010PF, one of several types of holders thatCOWELLS 90CW
For those who are unfamiliar with Cowells, they are small company located near Cholchester, England. The company was established in 1975. Their machines are hand built, to order, by an experienced tool room engineer. They produce several different machines, including a model engineer lathe (90ME), a clock and watchmakers lathe (90CW), a BALANCE - WATCHMAKING.WEEBLY.COM The recess in the balance is then bored out with a carbide boring bar to a depth of 0.95mm and 22.5mm in diameter. The balance is then parted off, about 1mm oversized. The extra width is to prevent distortion from the cutting pressure of the parting tool. Parting can be a stressful operation (to the lathe and the operator), and partingTOOLMAKING - WEEBLY
So, tilt the top of the graver slightly to the right until the point, heel and right corner of the square touch the stone. Now, make long strokes with pressure. (This is quite important. Two short strokes which total the length of one long stroke will roll the graver twice as much as the single long stroke.)CENTER WHEEL

COUNTERBORES
Piloted Counterbores. To bore the recess for a screwhead, a piloted counterbore is a useful tool. They can be purchased in standard screw sizes, and the only ones available in small 'watch sizes' are offered by Bergeon and are frightfully expensive. Making an equivalent type of tool, special for the purpose, is relatively simple.ESCAPEMENT - WEEBLY
This is a traditional goldsmith technique. The resulting surface of the sheet is uneven and must be faced or ground flat. Finding the actual diameter of the escape wheel is dependent on the watch at hand. The center distance is 6.6mm, this is calculated from the fourth wheel and escape pinion pitch circle radii.CENTER WHEEL
