Karma strikes.
I did have a perfectly good crankenstein when i wrote that this morning.
With 5 kg to go the drive shaft snapped. -_-
So after an hours dicking round with it and then getting the spong sausage grinder out, and then finnishing it off in the food processor and sending the CAS off to be be rebuilt i am finally mashing in.
Good news is that due to a conversation with a mate, about my un forseen circumstances he has told me about a commercial unit at a stables they don't want for $50.
Worst comes to worst i'll use my wholesalers price at kegking
