So I'm following the guidance from the YouTube video called "How to make a flange for EMT conduit" and it isn't working. I'm working with 1/2 inch so I have a 1/2 inch compression coupling that the video says should thread nicely into the 1/2 inch pipe flange I bought. It doesn't. Not even close. See photos. I'm pretty sure I have the right parts.
