You can disagree all you want. I'm a journeyman Steamfitter with 20 years experience. I've seen first hand the damage using the wrong materials brings. I've had to fix a lot of "but the book said..." disasters. Do what you want, I just gave my professional opinion.
NEVER EVER use type "M" copper for compressed air use! The best is black pipe. Don't use galvanized as pieces could flake off and get lodged into orifices or shoot out of an air nozzle. If you must use copper, use type "K" (refrigeration). If you don't want to spend the money on "K" use "L". "M"...
If at all possible, use type K copper. It's thicker. By all means, have a flexible connector between your air compressor and the rigid copper on the wall.
Make sure you aren't on the hook for soil contamination clean up. I've seen where existing companies are grandfathered in and when the property is sold everything has to come up to code, including environmental issues. I'd hate to see you stuck with someone else's big dollar problem.
Thank you, your responses mean a lot. I have a possible lead so I'm keeping my fingers crossed that it happens before he's too weak. If it happens, I'll video and share it.
My name is Del Swanson and I'm losing my brother-in-law to Cancer. We are a car family with mostly old Fords ranging from 1937 to 1967. We respect and understand old cars and hot rods. Mike, my brother-in-law, has always loved Cobras and wanted to build one someday.
