A How To Video on how to rebarrel a 700 did wonders for me about 10 years ago. It's not as hard as one may think, but then I don't consider rebuilding an engine or tranny difficult either. It's alot like reloading go slow and double check often.
Yes Sir, I do plan on doing all the work by myself I did buy a lathe, while its not the biggest in the world it should get me by, Do I really need to spend 20 + Thousand dollars to learn how to build custom rifles?
If you have a lathe already then some advice. Read everything you can. Start practicing on scrap or old barrels. You can also try apprenticing for a local gunsmith as well as machining classes at your local comm. college.
