When using the FV turnouts with mare scale flanged wheelsets there are two areas of concern:
1. The cast frog assembly will not allow these wheelsets to run through the turnout. The wheelsets will drop into the space between the points and the closure rails. To address this issue, I added 0.020 X 0.60" spacers attached with JB Weld. This allowed the scale wheelsets to ride over the space in the cast frog assembly (see Illustration).
2. The guard rails allowed the tread of the scale wheelsets (Code 110 and 125) to be misdirected through the turnout causing them to derail. To address this issue, I decreased the width of the guard rail by attaching a 0.030 X 0.100 spacer to the original guard rail. I roughed up the guard rail with 100 grit sandpaper to increase the bite for the adhesive (I used Eileen's "The Ultimate" ). I painted the spacer with American Accents by Rust-oleum. Color: Espresso, a perfect match for the original FV guard rail. The spacer is difficult to see in the illustration as it has already been painted.
Haven't had any problems in the two years I have had over 20 turnouts on the layout.

My understanding from this is that those two shims you JB weld onto the frog allows the flange of scale wheel sets to maintain a reasonable height to allow them to continue through, is this right?
The bit I am confused with now is that if you have shimmed the frog to run scale wheel sets through nicely, won’t hi-rail wheel sets ride up higher onto the shim and you will have a gap between the rail head and the wheel?
Or have I missed something here?
