I do not machine castings for customers apart from plain wheels for diesel locos.
Different machinists have their own preferred methods of mounting wheels:
Walsall Model Industries can machine my castings and mount them on their square ended, self quartering axles. Insulation where required is inserted across the individual spokes.
Steve Ross uses Tufnol or Delrin hub insulation where required, mounting the wheels on round-ended, telescopic jointed axles quartered and kept in position with a taper pin.
His contact details can be supplied on request.
CASTING MATERIALS:
Castings for Gauge One and larger when made in cast iron suffer from a small number of random, unpredictable rejects due to crumbling of the ceramic casings for the thicker castings. Test castings in 2024 in mild steel produced a similar amount of rejects, not from crumbling casings but from voids caused by trapped gasses. It is possible that the trapped gasses could be released by making all new tooling with additional offset feeds. Two grades of low carbon steel were tried. Both are harder to machine than cast iron. Steel Grade CLA 1A is the softer of the two but is less machinable and not suitable for form tools. Grade CLA 8 is slightly harder but is more machinable. CLA 8 tyre profiles can be cut with a form tool.
For now at least, new castings will be made in grey cast iron Grade BS 250. It is self lubricating during machining and does not form burrs. There may be some delays if failed castings have to be replaced in a following batch.
