Weld the plant & sun gears together & to the casing 
Easy.
But dont weld the entire hole up with the planets are as you still gotta be able to take the diff apart, you should be able to get to the circlips that hold the driveshaft bells in.
Only things that'll give up after that are the CWP & snappin drive shaft bells in half or where the pinion bolts onto the prop.
But it is a hell of alot stronger I went from breakin 28 diff's in a year to about 7 I think so you could say their 4 times as strong lol
You can see from this pic what I mean, ignor the failed CWP lol

cheers jb thats a great help! is it weldable just by taking the end casing off or do you have to take the internals out aswell? looks like this is my next job... weld all the gears together and what you mean by weld the casing aswell?

Weld the plants & suns to the diff casing. Dont weld in the centre cos if you bust anything you wont be able to take the diff apart 
You can weld it in situ if you want but be sure to give it a huge clean after cos splatter from the welder could get on the CWP & damage em the second the drive the car.
Last one I did was in situ & has lasted so far
(bout 6 months now)
Will try find more piccy's

Testing the future
i put a plate in there as well on mine so that the only things that could possibly break could be the pinion or crownwheel. i removed mine, drained out all the old oil, cleaned it thoroughly with brake cleaner and stuffed it full of rag to catch any spatter.
