A portable articulated arm coordinate measuring machine (AACMM) is provided including a manually positionable articulated arm having opposed first and second ends. The arm includes multiple connected arm segments. Each arm segment has a longitudinal axis. Each arm segment includes a generally tubular core, an outer sleeve surrounding at least a portion of a length of the core, and at least one position transducer for producing a position signal. The outer sleeve is a cylindrical tube having a first portion at a first end and a second portion that extends from the first portion to an opposite end. The first portion is coupled to an end of the core. The first portion is shorter than the second portion and the second portion is configured to move relative to the core.
