i made it like this: 2" malleable male fitting that i cup some threads off and screwed halfway in a 2" copuling, then i cut out a aluminium ring (3mm thick) and a rubber gasket the same way as the alu plate.
you do it like this, put in the aluminium ring that rotates when you are screwing it all tougether so you don't damage the disk, then the disk on the ring, then you put in the gasket and screw in a brass 2" male nipple to clamp it all together.
enough talk look at the pics. (nipple side of it is for the chamber)
if the disk's slip out of this one you wont hear more from me because i will shoot my head off
