I just rethreaded the bung on my compressor to run 1" ridgid around my shop. (I know its overkill, the 1" is t-tapped for 3/8 drops). It can be done, not sure if final product would leave evidence of earlier problem. The internal pipe taps or bolt taps are all over the swap meets, as they are used 1000 times less than there counteparts. No one ever thinks that they will have a use for them.
