An emergency position indicating radio beacon ("EPIRB") includes a watertight housing with an ON-OFF switch on the outside of the housing which does not require holes through the housing wall. A floatation collar on the housing maintains the EPIRB in an upright position in the water and provides a storage cavity for a lanyard. Conductive grids on the interior of the housing either shield the EPIRB electronics from antenna radiation and form the lower half of the antenna, or couple the antenna to the water which acts as a ground plane, depending on whether the EPIRB is floating in the water or is surrounded by air.

A method of assembling a shaft of a magnetic motor comprising the steps of providing a plurality of magnets (), providing a plurality of pole pieces (), stacking (S) said magnets and pole pieces to form a subassembly () having an outer surface of a first diameter, providing a precipitation hardenable stainless steel sheet material, forming said stainless steel sheet material into a tube (S), drawing said tube to form a precision tube having an inner surface of a second diameter (S), said second diameter being greater than or equal to said first diameter, heat treating said precision tube to form a tubular sleeve of a Rockwell C hardness of at least about 40 and a magnetic permeability of at least about 100 (S), and inserting said subassembly axially into said sleeve (S), thereby forming a shaft for a magnetic motor.
