Wheels
Hi John,
I have not had problems with concentricity after restaking the wheels. I chuck them on the pinions in the lathe and check for that. A big problem is that they are no longer really flat and it takes forever to get them flat again.
As far as I can tell these wheels are all brass. I know that the ratchet wheel on a 2824 is CuBe so I am not planning on filing around on that one. But CuBe is much redder than brass and also more difficult to bend so it is not hard to tell the difference.

Fascinating..
Great report, Kong and Fantastic work, Don. One question. The crown, what material is it? I may have missed it in the text, but the only reason I can think of for casting before machining is that it's a precious metal of some sort, hence the need to minim...
Casting
Hi BDLJ ! The reason I do casting is because after casting the work that remains is simple turning and hand work. I do not need a big CNC for a quarter of a million with a complicated program to mill the case or even the 10s of thousands of CHF of investm...
very cool! a question and a comment
Hi Don, This is a great series and highlights how much work you're putting into these pieces. Keep up the good work! How do you maintain or re-establish concentricity between the pinions and wheels after dismounting/remounting them? Do you top the wheels ...

Thanks very much Kong and Don! Another question for Don,
Will you ever try gilt frosted finishing like on Greubel Forsey watches instead of geneva stripes? Just wondering. Some people like the frosted finishing better (I'm not one of them) so thought I'd ask this in case you ever make a custom ordered watch in ...
Pure poetry
To actually see the work you put into each piece is a glorious thing indeed. To me, it's mechanical poetry in motion- always striving for that moment when the true surface of the parts is found. Just like hitting the final facet on my stones, you must rea...
