I don't know about "gorgeous", to me it still feels like Frankenstein's bride.
I found a picture I took of the manifolds before welding. It 's easier to see how they are laid out. The manifolds with threaded nipple pipe are the HLT/MLT/HEX/HERMs (Pump 1) supply and return manifolds (top left and right in the pic). The bottom two are Pump 2 supply and return manifolds. Supply manifolds are 3/4" and Returns are 1/2". The main tube is 1".
All fittings had a radius machined so that they would fit perfectly on OD of the tube for welding. I honed the ID of all tubes and fittings prior to welding (2nd pic)
