I have a flush cutter that I used and a 1/16" hole punch with a block of wood that has a hole large enough to allow the pin to be driven into the hole. Prior to using the punch, I do use the flush cutter to "lift" up the other side, giving me enough room to secure the punch without chance of it slipping over the top of the scale. Then the scale on either side of the pin is supported by the block of wood. It's punched out a number of pins, this is the first one that broke that I didn't notice a prior crack in.
