Welcome aboard!
ALL sorts on here, clock makers included.
Try to find a local, M E club and join. You will mingle with folk with similar mindsets, experience, from which you can benefit.,
Remember that there is NO perfect lathe. Some are better for some jobs than others. The skill is in getting the machine to do what you want, to the standard that you want.
Learn how to provide a steady hand feed. There will be times when you need that skill, even if the machine has power feeds..
If in doubt, get a lathe which is a bit larger than you first thought. Your horizons will expand, and you can do small work on a big lathe. The converse is not as easy!
Before launching into machining expensive metal, get to know the lathe, and what it, and you, can do..
Learn by making a few tools that you will find useful in the future. These may well include a Centre Height Gauge (For rapidly setting tools to centre height son that they cut as intended. ) You may find the time spent in making a sliding Tailstock Die Holder, and sliding Tap Holder. You will almost certainly find a use for a Tap Wrench. You can buy just the Die Holders from Arc Euro and make a suitable body to carry them.
If you are cutting threads upto a shoulder, or down a blond hole, making a Mandrel Handle will be time well spent. Chances are that whatever lathe you buy, evn in Back Gear, is bit fast for such jobs. (and getting a broken tap out of a hole is not easy. Usually means staring all over again with new metal.
If you are clock making, you will ,not be looking to remove lots of metal in one fell swoop, so think in terms of HSS rather than carbide. A HSS toolbit will cost about the same as one carbide tip, but can be ground MANY times (Eve at 9:00 pm on a Saturday evening when everyone is shut. ) You will also learn how to grind tools. A sharp, properly ground tool can solve a lot of problems.
Buy one or two books on lathe operation and study them (lots to choose from, by former editors of M E W(Stan Bray, Harold Hall, David Clark, Dave Fenner, Neilk Wyatt. ) L H Sparey tends to concentrate more on the Myford ML7; but the basic principles;es are the same; just the detail that differs some time.
As they say in Suffolk,"Make haste slowly".
Time spent learning the basic principles and techniques will make life a lot easier in the future
