Pictured here is a large nylon bench block. It measures 4 inches in diameter by 3/4 inch thick. The large face eliminates much of the balancing problems when you're driving out pins. Also cannot mar surfaces. Drilled with four through holes for easier pin removal and disassembly. Convenient center "V" holds cylindrically shaped parts steady so they won't roll. Can be drilled or modified with your own hand tools.
Perfect for the gunsmith, hobbyist, machinist or inventor!
