[Microwave] quarter inch hardline solder connectors

[KD7JYK DM09]

It's been a while since I've worked on such things, but from my experience 
in the past, center pins are just pressed into the teflon, usually with some 
length-wise ridges to prevent rotation.  I've seen this from the smaller SMA 
connectors to PL-259 and N.

In the past I've pressed them out, if big enough with a piece of metal tube 
over the pin and pressing against the shoulder, if there is one.

On small pins, I've risked pressing VERY carefully against the pin tip with 
a metal rod or bolt or screw with a small vice.

I've never had a problem, but there always COULD be one.
