Materials:
Ideally (as early prewar Carriers) Manganese Steel would be use, however this is very machining intensive - read costly.
During the war they used MCI which today has been superseeded by what is known as S.G. (Spheroidal Graphite) and is ever so easy to cast, my dad does at least two melts per week, just a little heat treatment and it's ready to be machined. It has mechanical properties very similar to Steel.
You may have read that I have just aquired two Loyd Carrier wrecks, as such I will have to be manufacturing a hell of a lot! We will need to have 8 Sprockets profiled and machined then hardened, new brake drums cast. At least I have half a set of track with them! Will keep you informed as the manufacturing process gets going.
