An electrical lapping guide is disclosed which is suitable for use with a single slider having a magnetic recording head. More specifically, a golf club shaft that is capable of minimizing or eliminating swingweight variations within a golf club despite being cut down to various different lengths to accommodate the length and heads of a set of irons is disclosed. The particulate material thereby is passes between the endless belt and the conveyor belt and any bouncing movement of such material is prevented. The container can include two internal compartments, one being more water-tight than the other. To make the utility platform independent, a standardized power and configuration interface is used to implement a computer system reset that preserves the contents of the RDRAM.
