Excellent work Steve. That table of fittings look$ like about $7-$800 ??? You are going to be either very sore or in very good shape when you get that header finished !! Good thing that you are young !! I'd have to hire that job out,, or I'd have to buy a REALLY BIG bottle of Motrin !
Looking forward to seeing that whole setup from a 'step back' photo, or a wide angle photo.. That is going to be an impressive showcase of pipefitting !!
Take care, and go clean the pipe dope off your fingers !!
