Just to finish off the topic -
Ended up getting the 100mm coupler, cost around $50 :scared-eek:. In the end I was just feeling lazy and went for the ready made option.
Had to convince the folks at Reece that such a thing must exist... I'm glad I took the pipe section with me because the first thing they said was "oh that part just slips over the pipe", talking about the big end of the reducer... When I held it up to the pipe and showed her, she reckons, "well that's not a part that we stock so you'll have to go back to where you got it and ask them". I politely told her I made it, and it was actually a standard piece of pipe..."oh well yeah you just weld them together". Me: "a butt joint? that doesn't sound right, that would be weak as hell?", "Yep, that's how they do it".
Me: :violence-smack:
Meanwhile another lady is looking through their catalog on the computer... "hang on, I think this is what he's after". The other lady didn't want to talk to me after that, out the back to lick her wounds I think. She did say when I was on the way out "that stuff isn't very common anymore" or something - no shit, it's expensive as hell!.
So thanks computer lady at Reece, for actually taking a quick look and not giving me bullshit like the other one.

This isn't actually the flange that it's being soldered to, just what I had on hand at the time.
