String and Sticky Tape Experiments: Simple Self-Lubricated Electric Motor for Elementary Physics Lab.
Entrikin, Jerry; Griffiths, David
Physics Teacher, v21 n6 p398-99 Sep 1983
The main problem in constructing functioning electric motors from simple parts is the mounting of the axle (which is too flimsy to maintain good electrical contacts or too tight, imposing excessive friction at the supports). This problem is solved by using a pencil sharpened at both ends as the axle. (JN)
