Today I tried making a winding shaft for 02. Unfortunately, I made the slot for the pull out piece at an early stage with the result that it snapped into two while I was turning the other features. Here is a picture
This is the reason why I am maintaining a log for 02. I have made this mistake before & if I had documented it I could have saved half a days work. The log will be a sort of a detailed account of how the No.1 skeleton watch is made. So, I can read up the bit on winding shafts before making one for 03 or any subsequent piece. Over time & with practice I hope this knowledge will become intuitive.------------------------------------------------------------------------------------------------
Anyway, I thought I might show you how I started work on this design. First of all, I required a 3D CAD model of the movement I had selected (the molnija 3602-3). Since I am an industrial designer I am fairly proficient with Rhinoceros (a 3D modelling software). So that is what I used. Below is an image of an early, incomplete model.
A 3D model would allow me to see the movement in a totally different perspective. I could also try as many designs/ themes with endless variations relatively quickly & without even touching a real movement. So I think the few weeks it took to make this model were well spent.-------------------------------------------------------------------------------------------------
The No.1 is a skeleton wristwatch. In the image below you can see the theme I selected. I wanted to lay bare the workings of a mechanical timepiece. What better way to do this than to accentuate the escapement.? Over time I developed this idea further through other devices (e.g.. finishes).
-------------------------------------------------------------------------------------------------
Below is a 3D model of what the watch might look like. The case was imaginary since, at that stage, I had not selected one for my watch. This went through endless revisions, each element was changed & refined till I was satisfied with it. Mind you, the true test is when you finally make it. I had decided on a certain dial marker on CAD (after days of trying options & refinement) but it just could not be finished properly when I actually made it. 
I hope I have better luck with the winding shaft tomorrow.
This watch dates back to 1892. It has a sterling silver case & an english lever escapement. It also has Geneva stopwork, an alternative to the fusee. Unfortunately, the finger piece is missing. I shall have to make it at a later date. What I love best about this watch is the loud, laid back pace at which it beats (14,400 bph). 
I have been fixing it's problems for two years now (as my knowledge & skills improve). The centre wheel was stripped off it's pinion when I got it. I tried re-staking it but it did not work for too long. Finally I found a replacement wheel from a junk movement. This replacement wheel was a fit but it was not as free as one would like it. There wasn't enough end shake. Finally, I was in a position to fix it. Since I was a little bored with turning all those dial markers, I decided to do this little project. Here, you can see how the end shake was adjusted on the turns. I had to turn a special turning arbour for this job. The wheel is friction fit on the arbour and this assembly is turned by a split ferrule. Admittedly, the ferrule does not fit the arbour well. But I did not find it worthwhile to make adjustments for such a small job. Also, the ferrule is one I made a long time ago. When I compare it to the one below (in the post about the winding shaft) I realise that my skills have improved marginally :-) 
What I will do in future is use 3mm stock to make turning arbours. I have made a split ferrule that fits 3mm stock perfectly & that way I will also be adding to my arbour inventory. Aditya
