I kind’a knew that when I mentioned that I created a manifold for Ronin, I should have put the word in scare-quotes.
What I did was really very simple. All I needed were a few stackable “Tees” and elbows. What I wanted to achieve was a fixed and clear distribution of the high pressure lines. So, on that note, behold!
