GRAPHITE RESISTORS

2016-3-6 · The pencil graphite rod is exactly 2.2 mm in diameter, and you need a 2.1 mm drill fixed in a vise as seen above.And I''m serious here. Not 2.2 or 2.0 mm but 2.1 mm. The reason for this is that you have to twist 0.8 mm copper wire 5 times around this 2.1 mm drill, making it a fraction smaller than the 2.2 mm graphite rod.
