Welcome Tony,
There is a mine of information on this site, from beginners to the very experienced, from all walks of life so don't be put off by any doubts as to your capabilities, we all had to start somewhere. You infer that you don't want a lathe or have I read you wrong? there are a lot of starter projects that are eminently suitable for beginners which would require a lathe for some of the machining of parts prior to assembly as well as some milling work so give it some thought.
There are plenty of members who, I'm sure, would be happy to pass on drawings that would help you via pm methods. I would suggest that you start on a simple oscillating engine as a first project as I have done, there are hundreds to choose from & plans aplenty. I have been involved in Engineering all my working life & now being retired have some time to potter in my 'man cave' now I have it to my liking & have built a double acting oscillating engine as a first project which I thoroughly enjoyed making, but has sadly been 'removed' by some low life along with quite a few other items in March, but that's another story so don't let me put you off.
Decide what you want to do, plan your budget, & go to it, it's a great therapeutic exercise once you get in there & start 'pottering' about, I have made a few tools to make things with, as Nobby says it will help your skills & If I can help in any way re.advice / methods etc. drop me a pm.
Happy Pottering.
George.
