Okay got an update for those interested in this thing.
First JB Water Weld and copper don't play well together I have no idea why because it says it works for metals among other surfaces. I keep having to add a little more as the copper tubing separates from the set up epoxy dough. I chose it because: it is good to 70 PSI, temps up to 250 F and is actually food grade compliant (no chemical leaching).
I may just have needed to use more than I did, I'll ask my hardware store buddy.
Second a minor nuisance, hopefully fixable, the shut off valves were VERY hard to open and close on today's test run, another question for my guy.
Lastly big upset was that after all the work it took making the butterfly collars to hold the bottles firm and straight it turns out they soften up in warm water so a bunch of the bottles were leaning at all angles. So I have to find something to replace them with.
Everybody feel free to chime in here if you have a comment and ideas are more than welcome (especially if your name is Evily who is an engineer
) Critiques are welcome even though I've already glued the thing together.
Here is a close up of what I used. You can see it on one of the pics above.

As a side bummer I discovered that using the BrewMate was not going to help with my hard water issues so no cheap oxygen cleaner for me.
I am pleased with how it worked, in principle the first washing session did all I was hoping for, it just needs some tweaking which is to be expected.

I so have sink envy. That is an excellent DIY project, well done.
