roll pin punch

I have done a hundred searches on cv joints so no one yell at me, but I am having a hard time finding any DIAGRAMS of half shaft removal. I have got the general idea, but what is the best means of removing the roll pin? And what size punch would you use? Are there any other tools I should be aware of? If anyone has a link to pics of removal using the three bolt method please post them, I already have the shafts, I just need a point in the right direction.

Thanks,
Crash
