I repair clocks as a hobby and have now started to build clocks from scratch. In my tiny workshop in London I have two lathes: a Cowells and a Myford ML10, but no drill stand, milling machine or means of dividing. I am thinking of investing in some additional tooling, especially for gear and pinion cutting. As as a member of a horology club I have access to an old wheel cutting engine where I have cut missing wheels for clocks under repair and the initial set of wheels for the going train of my current clock. The club also has a drill stand and a milling machine which I can use to cut my pinions. My latest clockmaking ideas however involve cutting some quite high prime number wheels not available on the club's wheel cutting engine. My ambition is to make an equation of time differential, which requires a year wheel (365 = 73 x 15 or 366 = 61 x 6), and possibly a clock with both a sidereal and mean time train which would also need quite a few exotic primes. I am thinking that acquiring a smallish but high quality milling machine (such as a Cowells) together with a dividing head coupled to an electronically driven servo motor could be the answer rather than, say, a dividing head to be fitted to either of the lathes. Any thoughts or suggestions would be appreciated.
