Trailing Truck

First job to tackle was to clean up the truck casting and machine the pedestal faces.

This was about as far as the machining went, as I found a major error in the casting. Well perhaps not the casting more the drawing. So very shortly this casting will be back in the pot and a new one from the modified pattern will emerge, so more of that later.

Just to keep things ticking over and to keep my learning curve on the up I did a bit of CNC work on the truck springing next.
