Building a Wye

[hornblower]

I used a basic CAD program to draw a wye with 22" radius diverging routes.  I then used a full scale printout as a pattern.  I used WS Accent Cement to temporarily glue printed circuit board ties to the pattern, then cut, filed and soldered the various rails in place.  This wye sits at the top of a helix allowing trains to enter either the helix or a mid-layout staging yard.  The biggest challenge was filing the rails to create the frog and that wasn't much of a challenge.  I used a Fast Tracks frog and point filing jig to file the frog rails.  I soldered the frog rails together using a #6 angle jig I made from a piece of plywood, then carefully curved the two frog rails to match the curves of the wye pattern.   That was it!  The rest of the wye was constructed with no more challenge than that of a standard turnout.

This might help with a "different' way to lay out a wye

For my H0n3 wye I built the turnouts with curved diverging legs.

A lot of factors such as what type of switches you are using (standard vs equilateral/wye), what number switches (#4, #6, #8), the angle the tracks intersect, the brand of switch if you are using commercial switches.

I would do as others have suggested and mock it up and measure from there.

Nominally if the two tracks intersect at 90 degrees (both wye legs the same) each wye leg would be 1/4 a 24 in radius circle or about 38 inches less the portions of the arc in the switches, so probably less than a 36" piece of flex track.

How about laying it out full size on some brown Kraft paper?

Does anyone know the size requirements for building an HO guage WYE using 24 radius track?  Is there a formula for figuring out the length of track required?  Any help would be appreciated.
