Given Martins oft repeated comments on establishing a " set" in the curved stock rail and the importance of the straight section adjacent to the planed blade, How does this work in curved turnouts , is there a " set " in both rails etc

Hi Dave,

There is a set on one side only, the same as a straight turnout.

A curved turnout is simply a straight turnout bent into a curve along the main road.

This means that all the sections which are straight in a straight turnout are curved to the main road radius in a curved turnout.

So beyond the set, the "straight" section* is curved at the outer radius. Then where the rails diverge the inner turnout radius begins.

The stock gauge remains the same and in the same position at the end of the planing, which is the same planing length. All the marks are on the printed templates.

In fact in Templot even a straight turnout is actually curved. It just happens that the outer radius is so large (over 50 miles) that you can't see it. To curve it, Templot simply reduces the radius from 50 miles to 5ft. :)

*assuming straight or REA semi-curved switches.

regards,

Martin.

Ok so the set still remains on the curved side. Does the straight section still remain before the curve begins. 
So then on the opposite rail there is no set and the rail initially curved at the outer radius and after the planing angle then curves at the inner radious 
Right ?

At the risk of incurring wrath, I think the answer is probably not necessarily so. From what I understand just because a turnout curves to the right does not necessarily make it a left hand turnout. i.e. you can have a turnout which curves to the left but could still have started out as a right hand turnout.

As Martin will tell you (I think) there is no such thing as a straight rail in Templot, just a very large radius, so from that, I think you can deduce that there will not be a straight section (of course I could be wrong but I think that was what Martin was saying).
