A little 'Ahh shit!' moment. The kingpin is well rusted into the eye. I have had the eye glowing red while under extreme pressure with the cramp only got a few thou out of it. I will let it soak overnight in penetrating oil and have a go again tomorrow. If we get a frost tonight I will hit the eye with the gas again and that might do it if I can keep the pin cold, speed being of the essence!
