A ruined dial

I have started making parts for No.1-04. The movement ring is done. I am working on the dial now. Everything was going well till I started drilling the minute markers. Halfway through I had an uneasy feeling about some of the earlier holes I had drilled (the holes are not clearly visible while drilling since they are under a paper template). This is what I found under the template-
If you look carefully you will notice that some of the holes at the six o'clock position (in the image) are a bit dodgy.

Here is a close up-
They are elongated. These holes are 0.4mm Dia. The problem was that I had allowed the drill bit to project too much out of the drill chuck. A 0.4mm bit will certainly flex when you drill brass.

Here is a closer look at the offending holes-

There is nothing else for it but to start over. Silly mistakes can sometimes cost an entire days work.

Pictures of No.1-03

My friend Sachin Kadam, who is an avid photographer, visited on saturday. He did not really know what to expect and just got his camera along (no macro lens, light tent etc.). All the same, I think he took some really nice pictures of No.1-03 (that was finished a couple of weeks ago).






Hope you like them as much as I do :-)
