This is perfect timing as I want to build a copper manifold for my 10gal MLT. I have a few questions if you can answer, I would appreciate it.
Why did you not do it all copper?
Have you used this for a batch yet?
What did you use to hold it together, lead free solder?
Any chance you can give some more detail on the copper manifold build?
I like your setup but it would be great if you could give some more details on the manifold so others could replicate it.
