I've swapped out a few silo doors and put them onto other razors, but sometimes have a hard time getting the silo doors off the hinges. Currently I get a small screwdriver like eyeglass screwdrivers and but the screw driver between the razor's baseplate and the inside of one side of the hinge and gently flex the hinge outward while pushing the end of the silo door inward to get it off the hinge pin. But some of those razors have tough doors and hinges that don't want to budge much. Is there an easier way to get those silo doors off?
