I was asked by email, how the heck does the pin puller sold (I think) by Sir tools work. Well, as shipped, it isn't obvious (had me going for a minute when I bought it) because it is shipped screwed together differently so that parts won't get lost. The two annotated pictures below explain how it is assembled in "working" mode and how it works. You should lightly oil this before and after use. Note the caveats in the pictures about keeping the tool parallel to the head. As long as you do this, and screw the threaded rod ENTIRELY into the pin (having cleaned out the threads in the pin), the tool will work very well. Operate it cockeyed, or only use a few threads into the pin, and something "bad" might happen.

When the job is over, reassemble it to storage (trapping the main threaded part) and put it and the other threaded parts in a bag. I actually STILL have all the parts, which in this house, is some kind of FREAKING miracle.
