Gap-less Turnouts, reducing wheel dips in turnouts
#5
Some updated ideas for this swing frog concept

I had previously written,...
My frog would be all one piece,...the short piece of rail attached permanently to a circular pin at one end,...something akin to this...

With that former iteration the diameter of the vertical pin was limited to the width of the head face of the rail, which can be pretty small.
How about we change this configuration so we have a more hefy size pin, and we don't bring it up flush with the top face of the frog rail. Instead we attach the pin/shaft to the bottom flange of the swing frog rail,...like these 2 possibilities

1) larger attachment surface area
2) easier joint to make (maybe even adhesive)
3) better/stronger shaft size

This new turnout as a whole is now easier to build,...less filing/grinding/fitting of adjacent rails, and less soldering.
one would still have to create the V-joint of the 2 rails leaving the frog area, but these 2 would not be the very pointy items they are today. They would end in a 'bluntness',..the width of running surface of the rail being used to build the turnout.

There would still be the grinding/filing of the 2 point rails where they meet the main rails. There likely would not be any gross pivot points between the point rails and the closure rails, but rather something like Shinohara used,..
