I also saw posted here... sorry I don't know who to give credits to but it's one of the regulars here....
The suggestion was to heat one side of the pin in the trunion and add oil to the opposite side of the pin. The advise was that the heat works to draw the oil into the hole around the pin. I know I had seen someone in the past that had a problem (in the last month or two) and this suggestion had helped them....
I have three more of these "G" kits to do so I may get a chance to do more experimenting myself...
Also, if you are doing this in a vise you are not getting anywhere near the force we get with a 12 or 20-ton press... You might need to find someone that can may let you use their press.
Oh yea, when doing barrel pins I ALWAYS wear safety goggles or a shield and I keep my face back... This is a world of force we are putting on a tiny 1/4-inch surface!
