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 MATERIAL:
In future castings for Gauge One and larger will made from mild steel although castings from older stock will be cast iron. This is to reduce the number of rejects from crumbling of the ceramic casings in the thicker castings. 0 Gauge castings will still be made in cast iron. The steel is low carbon mild steel grade CLA 1A as set out in BS 3146-1 (1974), Specific requirements for carbon and low alloy steel investment castings. External link.
The Mild Steel seems slightly tougher than cast iron. Using a form tool across the width of a Gauge One wheel casting I have taken a thinner cut (0.03 mm/rev) at 98 rpm. That is partly so that the nut on the end of the small mandrel can hold the work without slipping. It does not cut so well at slower speeds. It will cut dry but cuts much better with cooling/lubrication such as an occasional squirt of WD40 during machining.
