Im building driveshaft loops and called my local metal shop and all they have is S-40 pipe. Im having him call on some S-80 now. Is S-40 gana be thick enough? Thanks
6" Sch. 40 common pipe is .28 wall 4" Pipe is very close at .237 and if you can find 5" it is .258. I have used 6" several times and it works great. and is cheap.
