With inspiration from your jig and setup (Thanks!), I started taking some measurements, and made a few drawings. A friend transfered them into CAD, and made all the flanges.



Everything is made out of 10mm stainless steel, and I made it so that the CSP python exhaust gaskets will fit if needed.



I wanted as much contact surface as you can get, so I thought of these things:



The pipe will be notched a little and welded to them. I will be using 40mm (outside diameter) stainless pipe.



One of my buddies has a TIG welder, hopefully we can handle the job. I'll post pics of the complete stubs when they will be done
