My guess is he posted because he was/is hoping someone could help him get his tool working. However, he obviously was hoping for too much; it seems he overestimated our good will.
Whenever the pin in my tool gets stuck, it is because of an alignment issue; i 'fix' the tool by wiggling things. Yup, i understand that is virtually no help, but what do i know? When things around here don't work, i try to make them work. When other folks things don't work, usually there isn't much i can do about it, so i normally don't make a suggestion, or a comment.
