Hi Derek. I am not really into clocks, but I did teach myself to use a lathe, with a lot of help from this forum, whilst building my Electro-Mechanical Fibre Optic Clock.
You can see how useful the forum was if you take a look at my build thread in the clocks section.
I had never used a lathe or milling machine prior to building the clock and some of the strange shapes were my way of experimenting with ways of using the two machines. I am still learning with the help of all the many very skilled men on here.
Cheers, Dek.
