The removal of the needles is really not a big deal, all you need is two heavy strong (i.e. no Ikea grade) spoons. Simply pry the needle off using even pressure on both spoon handles. Make sure to put down some padding on the surface of the gauge face before using the spoons so that you do not mar the surface of the gauge face.

WEAR EYE PROTECTION!
