Subject: [FlyRotary] Headers

Does anyone have a good source for design and fabrication of headers for the
rotary? I want to use 321 stainless X .065 wall at the inlet but what
practices should be observed as far as  slip joint construction?  Do you
expand the tube to fit over the same size?  Do you purchase different size
tubes? What is the preferred design of the slip joint? Is wall thickness
maintained throughout the length? Thanks for any help
