Hi Tony,
I might seem a bit dense here but looking at the society stores, the 3mm to 2mm axles are turned down to 2mm at the ends, to accommodate wheels with 2mm centres. Most RTR locos I know that use 2mm centred wheels also use 2mm axles so you would then need to enlarge the axle bearings, for your new 3mm axles. Or am I missing a crucial point?
