Help me set up my air compressor plumbing please!

I initially had the RapidAir System (from Wisconsin, largely Made in China) and have had several connectors fail over time, leaks. Replaced the problems with 1/2" galvanized piping end to end ---cheaper and bulletproof.

I've decided on a hybrid system with the manifold being copper then from the manifold to the hose reel and across 3/4" maxline. I'd have to price and see if copper would be more expensive or not than buying the 3/4" master kit plus a couple 90 degree elbows. I'm going to the plumbing house this weekend.

This is my rough diagram.
