Most of the constituent parts of the Universal Coupling have now been made up to the original drawings - some by us in the home workshop - but the EN24 parts - a very tough steel, were farmed out to the "Professionals" to machine for us, and the final part, the actual Drive Shaft (pictured) has just come back from them.
This just leaves the Coupling Flanges to be finished with a "Square" for the coupling wire cut in one and a Spline in the other one, after which final assembly of the unit can take place, and it can be installed into the Truck.
