I usually drill the door hinge pins out using a 7/32 " drill bit. When I am just about two thirds of through, I will put a drift punch in the hole and the old pin after a few taps will usually fall out onto the floor. In order to drill up close to the door, I use my right angle electric 1/4" drill. After this tedious drilling operation, I have always been able to go back to using the stock diameter door hing pins again.
