<p>A method of forming a rack (45) (e.g. of the type used in a geared system such as a rack and pinion), suitable for use in a stairlift rail, comprises providing a plurality (30) of elongate strips (10) and securing the plurality (30) of strips (10) together as a stack of strips (10) to form the rack (45). The strips (10) may be profiled to provide a profile to the rack (45). Preferably the profile provides a toothed rack (45). The rack (45) may be straight or curved. A rack (45) comprising a plurality (30) of elongate strips (10) secured together as a stack of strips (10) is also described.</p> |
