Removing Hammer Drive Pins ???

Has anyone any magic tips for removing Hammer Drive Pins? They are those, usually 1/8", hard steel serrated pins with a rivet head often used to secure brass plates and labels. Example here:

I need to remove quite a few from a machine I'm rebuilding - no problem destroying the pin but I need to preserve the labels, and when I've done it before usually end up ruining the label as the is no easy way of gripping the head of the pin.

I've had some success by grinding a slot in the head and winding them out with a screwdriver.

Try what Bob says first, but failing that drop a washer over the head to protect the plate then grind the head off with a small Dremel cut off wheel on it's edge, not grinding wheel. Then prise the plate carefully off and grind what's left flat, refasten when ready just to one side. Usually the old pins are still under the plate.

To this bodge artist, drilling is the first thing I would do. Oddly, had most success by getting the drill hole slightly off centre. It only potentially wrecks part of the original hole leaving it still usable, while allowing the pin to collapse enough to wriggle out, assuming the drill bit doesn't pull it out.

Though I assume that there is a very good reason in your case why that is not wise or possible.

I have used an old sheaf knife blade tapped in from either side under the nameplate wich allowed a pair of end cutter nips to get a good grip under the heads then a piece of plywood placed between end nips and nameplate acted as a lever step.
