I too am a beginner at building turnouts and laying track but I found some great articles in the "How To & Video" section on this site. These articles were a great start for me. There is even a digital download on how to build your own Rail Bender. These aren't free but the small price was worth the time I saved starting in the right direction.
How To & Video section: Digital downloads > Downloadable Articles > Track, Accessories and Details.
Good luck and have patience. I have just about finished my first turnout and so far, it works smoothly!
