I am at the stage of constructing my first 5″ railway points (Aiguille). I had armed myself with Colin Edmondson’s book ” How to build your own 7 1/4″ Gauge Points” and from the NET, “Karen’s little railway” guide plus the American blog from International Brotherhood of Live Steamers. As an addition, I bought “Loco-Revue 06 – Les dossiers thematiques”. This is a 114 page magazine (Journal) a French publication that details photographic construction of different forms of points and crossings and then goes on in detail for the smaller 1/87th ?? scale PICO, BAHN, ROCO etc rail geometries.
I appreciate that Loco-Revue 06 would not be available in the Uk but for French / European readers it may be of interest.
