Any cementing or solvent-welding of the broken point housing would be done after the feed is pulled out of it, and after the broken piece is unscrewed and removed from the interior of the section (that might take some heating of the brass; I think Waterman used a little sealer on the threads). After it's cured and any necessary cleanup of the joint is done, the nib and feed would be reinserted into the housing, and the housing screwed back in to the section.
It may be that the broken housing can't be reliably repaired, or the threaded part can't be extracted from the section without tearing it up, and then you'll need a donor part. I think, from what I can see, that the point housing is the only donor part that you'd need. You don't necessarily need to sacrifice your other pen for it, it may be available as a part from someone who has already torn down a broken pen for parts. Try contacting FPN member Dutchpen to see if he has one on hand (one with a gold ring, or that he could replate with gold).
I'm sorry I can't immediately recommend a repairer. A number of people should be able to do it if they see the problem (try e-mailing them a link to this thread) and have the part available.
