Andy,
The machines mentioned in the last few posts are all for metal turning, and if that is what you are looking for, although I haven't yet tried one myself, I too have heard very good things fromk people whose judgement I trust about the Sieg machines from Arc Eurotrade (**LINK**), and am even likely to buy one some day.
If, however, you and your father are rather looking for a small wood turning lathe to help with tapering masts and spars on a wooden ship model, the metal turning machines are likely to be less ideal. Yes, it is possible to turn wood on a metal turning lathe, if one can replace or turn the toolpost into a tool rest for wood turning chisels (or, possible, find or make up cutting tools suitable for wood that fits the orignal toolpost), but this is not what these machines have been made for, not least in that they usually cannot provide the higher revs that you want for really fine wood turning. Also, they are much heavier and need to be properly set up and, not least, they are more expensive!
For model ship spar and similar wood turning work, I use and have been very happy with the Proxxon DB 250 Micro Lathe (**LINK**). For an example of the kind of turning to which I've been able to turn (ha!) it, have a look halfway down this page of my Eilean Mòr thread on this forum: **LINK**.
Please note, though, that it is a micro lathe, i.e. there are limits to the available power, and also to the size of stuff you can fit in there (the maximum through-size of the tailstock spindle is 10 mm, the swing over the bed 40 mm and the centre distance 250 mm).
If one decides to get one, I would also recommend some of the optional accessories, in particular the headstock chuck and (in order not to be too limited by the range of the collets included in the standard package) the three-jaw tailstock chuck. I also have the four-jaw tailstock chuck, but have hardly ever used it.
I have likewise bought the five HSS mini chisels sold by Proxxon, and find them quite alright for the money, although one day, when I have some cash to spare, I shall probably splash out on these: **LINK** …
