track down these books:
-sculpting a galaxy
-star wars chronicles
-from star wars to indiana jones": the best of the lucasfilm prop archive (start with this. it's chap and great)
will do thanks for the tip!
That's where I started in '97-'98-'99, but now don't even look at these books. There's good info and inspiring pics, to be sure, but they will not be adequate to get you where you might want to be. It depends on how accurate you want to get. As I said, good reference is essential, and the reference pictures in these books are not always great. There is no good reason to trust the blueprints (where given) in them either.
For instance, as far as I am aware, there are no pictures of the Y Wing in any of these books that are good enough to give you an accurate plan for the underlying geometrical shapes. It can get really confusing, and you can't make out a lot of the detail, which makes identifying parts very difficult. In short, you can learn much, much more just by reading through the threads on this site that might interest you than you can by picking up those books. Here you can learn specific kits and parts. There, you get some pictures that, even if they are good quality, will not tell you what parts are what. It takes a lot of research and a lot of work. Save every picture you come across, and also save explanatory text.
But if you don't care so much for super accuracy (which is only possible up to a point anyway), and can live with quite a bit of inaccuracy, then have at it - and have a blast! Those resources (the books mentioned) might be all you want and need. No one can tell you what you have to do. But even if you get the books, you have to identify parts, buy the kits, make measurements, etc..
None of this is meant to discourage you, by any means. It can be a very fun and rewarding endeavor.
Especially when she finds out that you only need one part from an entire kit. lol.
Save all your parts! You may come up with your own original design you can use leftover parts to detail. And some kits may have parts for other SS builds. I have bought kits before on little more than hope, and was thoroughly disappointed that they didn't have what I expected. Then, after having them for a few years, I found that they actually DID have parts I needed (I just didn't have good enough reference to realize it) or that they had parts for a completely different model I hadn't yet considered. But have some guidelines - research kits that were available during the timeframe the model you want to replicate was first built.
