The method includes the step of eroding elastomer of the mass from around the conductive metal member to form a predetermined shape by exposing the lead portion to a jet of gas containing entrained, particulate abrasive. Preferably, the particulate abrasive is softer than the conductive metal member to avoid scratching thereof. For example, soluble particulate abrasive such as sodium bicarbonate can be used. | |
