Abstract
Apparatus is disclosed that includes a housing through which extends a shaft, such as a drill string. A body of wire mesh is carried by the housing and located between the housing and the drill string. The wire mesh is compressed to cause it to expand laterally into engagement with the housing and drill string to hold the housing from movement relative to the drill string, to attach, for example, a stabilizer to the drill string, or to support at least a portion of the weight of the drill string.
