Surely I can't be the only one? Everyone else knew they wanted to build planes, trains and automobiles?
No you're not, but it does help if you can focus on something. Have pity on the poor sods trying to answer the original question, which is extremely broad!
Clockmaking and motorbikes imply rather different equipment. On top of that your experience, your feelings about new vs secondhand, productivity, British vs Foreign, how much of that £5000 you're prepared to risk, competencies, aptitude, how much time and space you have, domestic limitations etc etc.
A career machinist intending to earn money fixing up classic cars after retirement wouldn't choose a Mini-lathe, but a mini-lathe is a good choice for a learner with a limited budget who wants to get a feel for practical lathe work with a view to trading up later.
I mostly use a lathe and mill in support of other technical interests. I'm also interested in learning metalworking skills as a hobby. I like exploring old techniques and odd jobs. I rarely do precision work nor do I make models for exhibition. (I've found building small engines to be an excellent way of stretching my skills, but I don't bother polishing, painting or presenting them.)
For general purpose work, the bigger the machine the better. My single garage workshop has to accommodate a bench with vice, a lathe, mill and band-saw, storage, a collection of hand-tools, and various other junk. It's a tight fit, and an advantage of buying new Chinese was being able to source the biggest mill and lathe that would fit into the floor space, while not needing me to upgrade the existing electrics.
I have a WM280 lathe, which is rather bigger than a Myford Super 7, and rather smaller than a Colchester Student. It sits across from a WM18 mill, which is the biggest I can also fit into the shared space. Providing decent working access to the machines was a consideration in my case: it's best to have plenty of room at the headstock end of a lathe so it can turn long stock, and not having the headstock cramped into a corner also it makes it easier to change belts and change-wheels. Similarly, the mill shouldn't be cramped because the table has a fair amount of right & left travel and overhang. The height of the mill may be an issue relative to your ceiling. – the WM18 fits within ordinary domestic headroom. Lathe and mill weigh about 250kg each and moving them with an engine crane is a man & boy job. An 800kg Colchester Student is proportionally more difficult to shift and floor loading & electrics may both be problems.
I started with a mini-lathe and learned a great deal from it. Main problem after a couple of years – too small. It lacks conveniences too, like t-slots in the cross-slide. After using a mini-lathe I had a much better understanding of lathes in general – what they're capable of, and their faults, features and shortcomings. At heart a lathe is a simple device and even unpromising machines can produce good results given time and skill. A professional full-featured lathe does the same job faster, demands less of the operator, minimises fuss, is 'nice' to use, and you get bragging rights. New professional lathes are gobsmacking expensive and very few hobbyists go that route. Second-hand is a good alternative, but condition is everything. Problem is that second-hand machines have history and if damaged, the spares aren't cheap, or even available. Evaluating a second-hand lathe isn't easy, especially if you can't see the thing running and are inexperienced.
Far Eastern hobby lathes have all the advantages of new (including money back if it's a dud), but they are not as refined or sturdy as professional equivalents costing at least 6 times as much. Mine benefited from minor tweaks but mill and lathe both worked out of the box and are still doing everything I want. I half expected to find I wanted something better, but so far so good. In the context of a £5000 budget and a high risk that family distractions will deny you workshop time, investing £600 on a mini-lathe as a learning aid might be a good investment compared with filling a workshop with doer-uppers and having no time to fix them.
Asking for general advice on a forum like this can be misleading. What people advise is determined by their experience, their budget, and their needs. In the end it comes down to how much risk and trouble you're prepared to go to in pursuit of your goals. That's why people were keen to know where you were coming from.
