Hi, first I just wanted to say how much I enjoy reading this forum. I'm always learning something new.
I'm trying to thread 1/2" Sch 40 black pipe with a Rigid 36890 1/2" NPT die head. I cannot get the die to even slip on the pipe. The bore of the die measures about .840 while the pipe OD including the black coating is around .853 on the seam. If I sand the coating off, it knocks off two thou. The pipe is Wheatland SureThread which I went far out of my way to buy since I wanted domestic pipe.
Is this a common problem?
