I learned to checker in '82 and checkered a couple dozen guns until about '93. I use Dembart tools obtained from Brownells Gunsmith Supply House in Montezuma IA. They have all the tools you need to checker. The first thing you need is a place to work. I prefer my basement as it has no windows and is quiet. A work bench with a single 75 watt bulb burning and no other lights on. Do not attempt to checker in natural light. As the sun moves, so do your shadows that you depend on when cutting. Next we need something to checker. This is an old .45 grip I made in the early 80's. It cracked at the lower screw hole and got tossed in a drawer. I screwed it to a block of wood so I can clamp it in the vise.
