I agree the fast tracks jigs are expensive, although I did toy with the idea of getting the blade filing jig - which I am led to believe through correspondance will accept Karlgarin 82 rail.
I personally find filing the crossing nose is not too hard although I do complicate it by making it a lap joint (see p25 of?)
The much harder part is holding the crossing and wing rails accuratley in place whilst soldering. On my recent work I have evolved my techniques to use sacrificial card overlays on a template copy with the crossing a wing rails (all straight and over long) held in place with masking tape. I failed to take photos of the soldering operation but hopefully the template photo is obvious - see:?
I have also moved on from trying to solder in the wires (as in track article) to using glued in black plastic snippets to represent the spacers in the flange ways and pieces of fishplate (zamzoodled) glued on the outer side of the rail.
