Echo (of this parish) very kindly re-drew my ham-fisted attempts at Templot for PSJ.
However, as part of the drawing he has used a few ''odd sized' crossing angles.
As it is currently too cold to inhabit the shed, and build the turnouts in situ, I thought that I would build them 'off the board' on a convenient piece of flat ply.
Bearing in mind that I normally use jigs, which mean that the crossing is normally assembled upside down, is there a quick and easy method of extracting the relevant set of points in a mirror image to assist in building up the common crossings?
I could just print the control template oin thin paper and use the non printed side, I suppose.
Any help much appreciated.
