Have an oval w/22" radius track. Want to make it an oval within the oval. What is the proper turnout to accomplish this?
THANX
Short answer, there isn't one.
You have a whole host of choices. Aside from the standard (with 18" divergent) turnout, you have #5, & #6 turnout. And the ever popular crossover. At a minimum you're going to need two of whichever turnout you choose. More if you want to go from the outside to the inside AND back again. At present I'm using 2 #6 crossovers. May revert to standard turnouts if ALL locos derail while going through them. But that's a different issue.
First decide what you can afford to spend on the turnout/crossover then and where on the layout you want to do this maneuver. Then go for it.

heres mine 22" outside and 18" inside with 2 #6 crossovers...no problem with derailment but the 18 will need 3" straights in the middle of the curves (http://i211.photobucket.com/albums/bb165/nitroburnr/IMG_8262.jpg)
As far as turnouts go avoid making an S curve whenever possible, especially with the 18" radius turnouts.
my advice, from sad experience, is to avoid the 18" radius switches like the plague. they are far more trouble than they are worth. #5 and #6 are far better choices and will cause much less trouble.
I have 2 #5 and 2 #6 switches now and have no prob even with the 2-8-4 berkshire
