from the factory i noticed, both ends of the pin are pressed, how do you get this affect when rebuiding door hinges? the rebuild kit just shows the pin goin through the bottom
Your not going to use a flairing tool on a solid steel pin. Not to mention you have to flair it after it is installed. The only way I know of is to install the pin, heat the straight end up until its cherry red, then take a large center punch and flair it with that. Make sure the other end is on something solid. An extra pair of hands makes this alot easier.
When I Cut Mine Down To Size I Drilled A 1/8 " Hole In The Center Then Installed The Pin And Took A Centerpunch And Mushroomed It
