Hi All

When making sharp curves, i.e. sub 800mm radius I have found that the standard way of producing 2mm track by using the track jig to produce a herring bone does not work.

I output the template from the track design package without the sleepers showing. This is because the package does not work correctly when the radius of the curve is sub 400mm radius. The template was cut out and fixed to the baseboard using masking tape.

I marked the mid point between the rails at each end and then with a compass set to the radius of 190mm I then fund the centre of the circle, using simple school girl geometry. Then I drew in the arc, the centreline of the track.

Standard sleeper spacing is is 30†which scales to 5mm. Using dividers I divided up the track centreline.

Then it simply a case of drilling a 1mm hole at the centre of the centreline arc, placing a pencil in the hole and then placing a straight edge against it and positioning the other end on one of the divisions on the track centreline and drawing the sleeper centreline.

Construction can now commence!
