I need to mount a GPS antenna. It has a 1-14 internal thread. 3/4" electrical fittings are similar, but they are .050" over 1". I need to thread something to fit. Can you thread the O.D. of 3/4" PVC pipe, or will the threads be too rough when you finish? I don't want to pay $11 for a piece of PVC with the thread that is made to mount one on a light bar.

I may have some 3/4" aluminum conduit left, but I don't have a 1-14 die.
