ABSTRACT:
A pull-through structure for measuring the flexure of a pipe or tube such as, for example, a gun barrel. The pull-through structure includes a laser beam detector which is freely swingably mounted in a casing forming part of the pull-through structure. The arrangement is adapted to coact with a laser beam emitter which is adapted to emit a laser beam substantially axially through the gun barrel. The laser beam detector includes a dead weight which causes an active detection surface thereof to automatically assume a predetermined angular position in the casing.
