I got some Slaters driving wheels at the Reading show, the replacement wheels had too much wobble and would not stay in gauge.
I have the premier coupling rods, but not the jointed ones, and not the rest of the motion.
I'm not sure which crank pins to use on the middle drivers, I don't like the 3mm diameter ones supplied by Hachette.
I think I prefer to get a kit all in one box and complete each major part before moving to the next, rather than the random sequence we have with this.
