Paul,
Although it is not in the picture, I do have the crown wheel already but do not have any pictures of the manufacturing 
.
It is not made with a cutter but rather with the help of a slitting saw, piercing saw and file. Rather tedious and time consuming. The straight parts are sawn with the slitting saw at a 10° angle. Then the rounds part are sawn with the piercing saw and everything cleaned up by filing.
