Still getting nowhere with this, had a friend of a friend round whose a mechanic and he's stumped as well.
I'm sure I saw a while back you can order a new clutch plate from this website, if so I will order one, and in a few weeks when it arrives the mechanic is coming round with his angle grinder and welding gear and will grind the welds off that centre shaft, hopefully replace the clutch plate, and weld it back up again.
Will take pics and post back when it's being done to let everyone see.
In the meanwhile, any thoughts about grinding it off??, fraught with danger or a last resort??
I don't see any alternative myself.
PS Looks like the clutch plate for the Diplomat 430 is not available so it looks more than likely a kill or cure strategy for the old machine
